The `simpleclient` data model is based on [OpenMetrics](https://openmetrics.io/), which is based on the assumption that each data point has exactly one `double` value (`Collector.Sample.value` in `simpleclient`). With the new Prometheus native histograms this is no longer true. Native histograms have a complex data structure as value. This is the reason why native histograms cannot be exposed in OpenMetrics text format. The new `prometheus-metrics-model` implements the current Prometheus data model and is not based on OpenMetrics. -* We refactored the package names. The simpleclient has package names that are reused by multiple Maven modules, which causes issues with the Java module system. The new `prometheus-metrics` modules each has their own package name, package names are not reused. +* The old data model was based on [OpenMetrics](https://openmetrics.io). Native histograms don't fit with the OpenMetrics model because they don't follow the "every sample has exactly one double value" paradigm. It was a lot cleaner to implement a dedicated `prometheus-metrics-model` than trying to fit native histograms into the existing OpenMetrics-based model. +* Version 0.16.0 and older has multiple Maven modules sharing the same Java package name. This is not supported by the Java module system.

However, renaming packages requires chaning code anyway, so we decided to clean up some things. For example, the name `builder()` for a builder method is very common in the Java ecosystem, it's used in Spring, Lombok, and so on. So naming the method `builder()` makes the Prometheus library more aligned with the broader Java ecosystem. + If you are using the low level `Collector` API directly, you should have a look at the new callback metric types, see [/getting-started/callbacks/](../../getting-started/callbacks/). Chances are good that the new callback metrics have an easier way to achieve what you need than the old 0.16.0 code.

You can configure this in code using the [OpenTelemetryExporter.Builder](/client_java/api/io/prometheus/metrics/exporter/opentelemetry/OpenTelemetryExporter.Builder.html), or at runtime via [`io.prometheus.exporter.opentelemetry.*`](../../config/config/#exporter-opentelemetry-properties) properties. + +In addition to the Prometheus Java client configuration, the exporter also recognizes standard OpenTelemetry configuration. For example, you can set the [OTEL_EXPORTER_OTLP_METRICS_ENDPOINT](https://opentelemetry.io/docs/concepts/sdk-configuration/otlp-exporter-configuration/#otel_exporter_otlp_metrics_endpoint) environment variable to configure the endpoint. The Javadoc for [OpenTelemetryExporter.Builder](/client_java/api/io/prometheus/metrics/exporter/opentelemetry/OpenTelemetryExporter.Builder.html) shows which settings have corresponding OTel configuration. The intended use case is that if you attach the [OpenTelemetry Java agent](https://github.com/open-telemetry/opentelemetry-java-instrumentation/) for tracing, and use the Prometheus Java client for metrics, it is sufficient to configure the OTel agent because the Prometheus library will pick up the same configuration. + +The [examples/example-exporter-opentelemetry](https://github.com/prometheus/client_java/tree/main/examples/example-exporter-opentelemetry) folder has a docker compose with a complete end-to-end example, including a Java app, the OTel collector, and a Prometheus server. diff --git a/docs/static/images/otel-pipeline.png b/docs/static/images/otel-pipeline.png new file mode 100644 index

Prometheus Java client for metrics, and the OpenTelemetry Java instrumentation agent for tracing. +OpenTelemetry’s [vision statement](https://github.com/open-telemetry/community/blob/main/mission-vision-values.md) says that [telemetry should be loosely coupled](https://github.com/open-telemetry/community/blob/main/mission-vision-values.md#telemetry-should-be-loosely-coupled), allowing end users to pick and choose from the pieces they want without having to bring in the rest of the project, too. In that spirit, you might choose to instrument your Java application with the Prometheus Java client library for metrics, and attach the [OpenTelemetry Java agent](https://github.com/open-telemetry/opentelemetry-java-instrumentation/) to get distributed tracing. -The Prometheus Java client has some awesome features under the hood to support integration with OpenTelemetry tracing: +First, if you attach the [OpenTelemetry Java agent](https://github.com/open-telemetry/opentelemetry-java-instrumentation/) you might want to turn off OTel's built-in metrics, because otherwise you get metrics from both the Prometheus Java client library and the OpenTelemetry agent (technically it's no problem to get both metrics, it's just not a common use case). -* `service.name` and `service.instance.id` are used in OpenTelemetry to uniquely identify a service instance. If an OpenTelemetry Java agent is attached, the Prometheus library will automatically use the same `service.name` and `service.instance.id` as the agent when pushing metrics in OpenTelemetry format. That way the monitoring backend will see that the metrics and the traces are coming from the same instance. +```bash +# This will tell the OpenTelemetry agent not to send metrics, just traces and logs. +export OTEL_METRICS_EXPORTER=none +``` + +Now, start your application with the OpenTelemetry Java agent attached for traces and logs. + +```bash +java -javaagent:path/to/opentelemetry-javaagent.jar -jar myapp.jar +``` + +With the OpenTelemetry Java agent attached, the Prometheus client library will do a lot of magic under the hood. + +* `service.name` and `service.instance.id` are used in OpenTelemetry to uniquely identify a service instance. The Prometheus client library will automatically use the same `service.name` and `service.instance.id` as the agent when pushing metrics in OpenTelemetry format. That way the monitoring backend will see that the metrics and the traces are coming from the same instance. * Exemplars are added automatically if a Prometheus metric is updated in the context of a distributed OpenTelemetry trace. * If a Span is used as an Exemplar, the Span is marked with the Span attribute `exemplar="true"`. This can be used in the OpenTelemetry's sampling policy to make sure Exemplars are always sampled. -TODO: We will add more information on integration OTel tracing with Prometheus metrics here. -In the meantime, have a look at the tail sampling end-to-end example in [examples/example-exemplars-tail-sampling](https://github.com/prometheus/client_java/tree/main/examples/example-exemplars-tail-sampling). +Here's more context on the `exemplar="true"` Span attribute: Many users of tracing libraries don't keep 100% of their trace data, because traces are very repetitive. It is very common to sample only 10% of traces and discard 90%. However, this can be an issue with Exemplars: In 90% of the cases Exemplars would point to a trace that has been thrown away. + +To solve this, the Prometheus Java client library annotates each Span that has been used as an Exemplar with the `exemplar="true"` Span attribute. + +The sampling policy in the OpenTelemetry collector can be configured to keep traces with this attribute. There's no risk that this results in a significant increase in trace data, because new Exemplars are only selected every [`minRetentionPeriodSeconds`](../../config/config/#exemplar-properties) seconds. + +Here's an example of how to configure OpenTelemetry's [tail sampling processor](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/processor/tailsamplingprocessor/) to sample all Spans marked with `exemplar="true"`, and then discard 90% of the traces: + +```yaml +policies: + [ + { + name: keep-exemplars, + type: string_attribute, + string_attribute: { key: "exemplar", values: [ "true" ] } + }, + { + name: keep-10-percent, + type: probabilistic, + probabilistic: { sampling_percentage: 10 } + }, + ] +``` + +The [examples/example-exemplar-tail-sampling/](https://github.com/prometheus/client_java/tree/main/examples/example-exemplars-tail-sampling) directory has a complete end-to-end example, with a distributed Java application with two services, an OpenTelemetry collector, Prometheus, Tempo as a trace database, and Grafana dashboards. Use docker-compose as described in the example's README to run the example and explore the results.

However, there's a `prometheus-metrics-simpleclient-bridge` module available that allows you to use your existing simpleclient 0.16.0 metrics with the new 1.0.0 `PrometheusRegistry`. So you don't need to upgrade your instrumentation code, you can keep using your existing metrics.

Over the next couple of weeks we will work on porting the remaining modules, starting with `pushgateway` and the Servlet filter.

 Histograms are for observing distributions, like latency distributions for HTTP services or the distribution of request sizes.
 Unlike with counters and gauges, each histogram data point has a complex data structure representing different aspects of the distribution:

 The terms "percentile" and "quantile" mean the same thing. We use percentile when we express it as a number in [0, 100], and we use quantile when we express it as a number in [0.0, 1.0].

 The 0.0 quantile (min value) and the 1.0 quantile (max value) are special cases because you can get the precise values (error 0.0) with almost no memory overhead.
 
 Quantile values are calculated based on a 5 minutes moving time window. The default time window can be changed with `maxAgeSeconds()` and `numberOfAgeBuckets()`.

 In general you should prefer histograms over summaries. The Prometheus query language has a function [histogram_quantile()](https://prometheus.io/docs/prometheus/latest/querying/functions/#histogram_quantile) for calculating quantiles from histograms. The advantage of query-time quantile calculation is that you can aggregate histograms before calculating the quantile. With summaries you must use the quantile with all its labels as it is.

 If you are using the low level `Collector` API directly, you should have a look at the new callback metric types, see [/getting-started/callbacks/](../../getting-started/callbacks/). Chances are good that the new callback metrics have an easier way to achieve what you need than the old 0.16.0 code.

-/**
- * Enable an endpoint that exposes Prometheus metrics from its default collector.
- * 
    
- * Usage:
- * 
    Just add this annotation to the main class of your Spring Boot application, e.g.:
- * 
    
- * {@literal @}SpringBootApplication
- * {@literal @}EnablePrometheusEndpoint
- *  public class Application {
- *
- *    public static void main(String[] args) {
- *      SpringApplication.run(Application.class, args);
- *    }
- *  }
- * 
    
- * 
    
- * Configuration:
- * 
    You can customize this endpoint at runtime using the following spring properties:
- * 
      
- * 
    • {@code endpoints.prometheus.id} (default: "prometheus")
      • 
- * 
    • {@code endpoints.prometheus.enabled} (default: {@code true})
      • 
- * 
    • {@code endpoints.prometheus.sensitive} (default: {@code true})
      •

 Reasons why we changed the API: Changing the package names was a necessity because the previous package names were incompatible with the Java module system. However, renaming packages requires changing code anyway, so we decided to clean up some things. For example, the name `builder()` for a builder method is very common in the Java ecosystem, it's used in Spring, Lombok, and so on. So naming the method `builder()` makes the Prometheus library more aligned with the broader Java ecosystem.
 
 If you are using the low level `Collector` API directly, you should have a look at the new callback metric types, see [/getting-started/callbacks/](../../getting-started/callbacks/). Chances are good that the new callback metrics have an easier way to achieve what you need than the old 0.16.0 code.
+
+JVM Metrics
+-----------
+
+Version 0.16.0 provided the `simpleclient_hotspot` module for exposing built-in JVM metrics:
+
+```java
+DefaultExports.initialize();
+```
+
+With version 1.0.0 these metrics moved to the `prometheus-metrics-instrumentation-jvm` module and are initialized as follows:
+
+```java
+JvmMetrics.builder().register();
+```
+
+A full list of the available JVM metrics can be found on [/instrumentation/jvm](../../instrumentation/jvm/).
+
+Most JVM metric names remained the same, except for a few cases where the old 0.16.0 metric names were not compliant with the [OpenMetrics](https://openmetrics.io) specification. OpenMetrics requires the unit to be a suffix, so we renamed metrics where the unit was in the middle of the metric name and moved the unit to the end of the metric name. The following metric names changed:
+
+* `jvm_memory_bytes_committed` -> `jvm_memory_committed_bytes`

+ * JVM native memory. JVM native memory tracking is disabled by default. You need to enable it by starting your JVM with this flag:
+ * 
    -XX:NativeMemoryTracking=summary
    
+ * 
    
+ * When native memory tracking is disabled the metrics are not registered either.
+ * 
    
+ * 
    
+ * The {@link JvmNativeMemoryMetrics} are registered as part of the {@link JvmMetrics} like this:
+ * 
    {@code
+ *   JvmMetrics.builder().register();
+ * }
    
+ * However, if you want only the {@link JvmNativeMemoryMetrics} you can also register them directly:
+ * 
    {@code
+ *   JvmNativeMemoryMetrics.builder().register();
+ * }
    
+ * Example metrics being exported:

 ./mvnw versions:use-latest-releases
 ```
 
+The versions plugin does not catch the `otel.version` in `prometheus-metrics-exporter-opentelemetry`. This needs to be updated manually.
+
+## Update Shaded Dependencies
+
+There are two modules for shaded dependencies:
+* `prometheus-metrics-shaded-opentelemetry`: OpenTelemetry data model.
+* `prometheus-metrics-shaded-protobuf`: Google's protobuf library.
+
+The shaded modules are commented out in the root `pom.xml`. Instead of using the shaded dependencies from the project, we use the latest shaded dependencies from Maven central (or from the local Maven repository in `~/.m2/repository/`). This way we can `include` the shaded package name directly. We find this easier than importing the original package name and have it renamed at build time.
+
+In order to update dependencies of the shaded modules (like Google's protobuf library or the OpenTelemetry library), do the following:
+
+Step 1: Install updated versions of the shaded dependencies in your local Maven repository.
+
+* Update the dependency versions in the shaded modules (both `*.version` and `*.version.string`).
+* `cd ./prometheus-metrics-shaded-dependencies ; ../mvnw install ; cd ..`
+
+Step 2: Update `prometheus-metrics-expositon-formats`
+
+* Change the version of the `prometheus-metrics-shaded-protobuf` dependency in `pom.xml` to `${project.version}`.
+* Update `PROTOBUF_VERSION_STRING` in `generate-protobuf.sh` and run the script to update the source code.
+* Use find-and-replace to update the version numbers in the imported package names in the source code of `prometheus-metrics-exposition-formats` and `prometheus-metrics-core`.
+
+Step 3: Update `prometheus-metrics-exporter-opentelemetry`
+
+* Change the version of the `prometheus-metrics-shaded-opentelemetry` dependency in `pom.xml` to `${project.version}`.
+* Use find-and-replace to update the version numbers in the imported package names in the source code of `prometheus-metrics-exporter-opentelemetry`.
+
+Step 4: Release
+
+_see below_
+
 ## Release
 
+Create a commit to temporarily add shaded dependencies to the project:
+
+* Add the `prometheus-metrics-shaded-dependencies` module to the root `pom.xml`.
+* Change the versions of the shaded dependencies to `${project.version}` in `prometheus-metrics-exporter-opentelemetry` and `prometheus-metrics-exposition-formats`.
+
+Release:
+
 ```

 ./mvnw release:perform -DreleaseVersion=1.2.0 -DdevelopmentVersion=1.3.0-SNAPSHOT

+`release:prepare` does GitHub tags and commits, while `release:perform` signs the artifacts and uploads them to the staging repositoring on [https://oss.sonatype.org](https://oss.sonatype.org).
 
 After that, manually verify the uploaded artifacts on [https://oss.sonatype.org/#stagingRepositories](https://oss.sonatype.org/#stagingRepositories), click `Close` to trigger Sonatype's verification, and then `Release`.
 
-Note: We release only the parent module and the modules starting with simpleclient. Currently, we manually remove the benchmark and integration test modules. Todo: Instead of manually removing these modules, we should reconfigure the build to make sure that these modules aren't released.
+Create a commit to remove dependencies from the build (undoing the first step):
+

Subject: [PATCH 079/870] Start HTTP server on the provided executor

The metrics HTTP server should run on a daemon JVM
thread so as to not keep the JVM running even
though all relevant threads have already exited.
Unfortunately, the OpenJDK builtin HTTP server
likes to spawn its own HTTP Dispatcher thread on
startup.
https://github.com/openjdk/jdk/blob/02c95a6d7eb77ed17ae64d0f585197e87a67cc4a/src/jdk.httpserver/share/classes/sun/net/httpserver/ServerImpl.java#L190
This new thread inherits the daemon flag from the
thread that started it, therefore we need to call
the start method from the executor service,
because those threads are daemon threads.

+title: Pushgateway
+weight: 5
+---
+
+The [Prometheus Pushgateway](https://github.com/prometheus/pushgateway) exists to allow ephemeral and batch jobs to expose their metrics to Prometheus.
+Since these kinds of jobs may not exist long enough to be scraped, they can instead push their metrics to a Pushgateway.
+The Pushgateway then exposes these metrics to Prometheus.
+
+The [PushGateway](/client_java/api/io/prometheus/metrics/exporter/pushgateway/PushGateway.html) Java class allows you to push metrics to a Prometheus Pushgateway.
+
+Example
+-------
+
+{{< tabs "uniqueid" >}}
+{{< tab "Gradle" >}}
+```
+implementation 'io.prometheus:prometheus-metrics-core:1.3.0'
+implementation 'io.prometheus:prometheus-metrics-exporter-pushgateway:1.3.0'
+```
+{{< /tab >}}
+{{< tab "Maven" >}}
+```xml
+
+    io.prometheus
+    prometheus-metrics-core
+    1.3.0
+
+
+    io.prometheus
+    prometheus-metrics-exporter-pushgateway
+    1.3.0
+
+```
+{{< /tab >}}
+{{< /tabs >}}
+
+```java
+public class ExampleBatchJob {
+
+    private static PushGateway pushGateway = PushGateway.builder()
+            .address("localhost:9091") // not needed as localhost:9091 is the default
+            .job("example")
+            .build();
+
+    private static Gauge dataProcessedInBytes = Gauge.builder()
+            .name("data_processed")
+            .help("data processed in the last batch job run")
+            .unit(Unit.BYTES)
+            .register();
+
+    public static void main(String[] args) throws Exception {
+        try {
+            long bytesProcessed = processData();
+            dataProcessedInBytes.set(bytesProcessed);
+        } finally {
+            pushGateway.push();
+        }
+    }
+
+    public static long processData() {
+        // Imagine a batch job here that processes data
+        // and returns the number of Bytes processed.
+        return 42;
+    }
+}
+```
+
+Basic Auth
+----------
+
+The [PushGateway](/client_java/api/io/prometheus/metrics/exporter/pushgateway/PushGateway.html) supports basic authentication.
+
+```java
+PushGateway pushGateway = PushGateway.builder()
+    .job("example")
+    .basicAuth("my_user", "my_password")
+    .build();
+```
+
+The `PushGatewayTestApp` in `integration-tests/it-pushgateway` has a complete example of this.
+
+SSL
+---
+
+The [PushGateway](/client_java/api/io/prometheus/metrics/exporter/pushgateway/PushGateway.html) supports SSL.
+
+```java
+PushGateway pushGateway = PushGateway.builder()
+    .job("example")
+    .scheme(Scheme.HTTPS)
+    .build();
+```
+
+However, this requires that the JVM can validate the server certificate.
+
+If you want to skip certificate verification, you need to provide your own  [HttpConnectionFactory](/client_java/api/io/prometheus/metrics/exporter/pushgateway/HttpConnectionFactory.html).
+The `PushGatewayTestApp` in `integration-tests/it-pushgateway` has a complete example of this.
+
+Configuration Properties
+------------------------
+
+The [PushGateway](/client_java/api/io/prometheus/metrics/exporter/pushgateway/PushGateway.html) supports a couple of properties that can be configured at runtime. See [config](../../config/config).

-# Maintainer Notes
-
-## Update Dependency Versions
-
-Use the [Versions Maven Plugin](https://www.mojohaus.org/versions-maven-plugin/index.html). Rules are configured in [version-rules.xml](version-rules.xml).
-
-```
-./mvnw versions:use-latest-releases
-```
-
-The versions plugin does not catch the `otel.version` in `prometheus-metrics-exporter-opentelemetry`. This needs to be updated manually.
-
-## Update Shaded Dependencies
-
-There are two modules for shaded dependencies:
-* `prometheus-metrics-shaded-protobuf`: Google's protobuf library.
-
-The shaded modules are commented out in the root `pom.xml`. Instead of using the shaded dependencies from the project, we use the latest shaded dependencies from Maven central (or from the local Maven repository in `~/.m2/repository/`). This way we can `include` the shaded package name directly. We find this easier than importing the original package name and have it renamed at build time.
-
-In order to update dependencies of the shaded modules (like Google's protobuf library or the OpenTelemetry library), do the following:
-
-Step 1: Install updated versions of the shaded dependencies in your local Maven repository.
-
-* Update the dependency versions in the shaded modules (both `*.version` and `*.version.string`).
-* `cd ./prometheus-metrics-shaded-dependencies ; ../mvnw install ; cd ..`
-
-Step 2: Update `prometheus-metrics-expositon-formats`
-
-* Change the version of the `prometheus-metrics-shaded-protobuf` dependency in `pom.xml` to `${project.version}`.
-* Update `PROTOBUF_VERSION_STRING` in `generate-protobuf.sh` and run the script to update the source code.
-* Use find-and-replace to update the version numbers in the imported package names in the source code of `prometheus-metrics-exposition-formats` and `prometheus-metrics-core`.
-
-Step 3: Update `prometheus-metrics-exporter-opentelemetry`
-
-* Change the version of the `prometheus-metrics-shaded-opentelemetry` dependency in `pom.xml` to `${project.version}`.
-* Use find-and-replace to update the version numbers in the imported package names in the source code of `prometheus-metrics-exporter-opentelemetry`.
-
-Step 4: Update `prometheus-metrics-bom`
-
-* Set the shaded dependency version property to `${project.version}` in `prometheus-metrics-bom/pom.xml`
-
-Step 5: Release
-
-_see below_
-
-## Release
-
-Create a commit to temporarily add shaded dependencies to the project:
-
-* Add the `prometheus-metrics-shaded-dependencies` module to the root `pom.xml`.
-* Change the versions of the shaded dependencies to `${project.version}` in `prometheus-metrics-exporter-opentelemetry`, `prometheus-metrics-exposition-formats`, and `prometheus-metrics-bom`.
-
-Release:
-
-```
-./mvnw release:prepare -DreleaseVersion=1.2.0 -DdevelopmentVersion=1.3.0-SNAPSHOT
-./mvnw release:perform -DreleaseVersion=1.2.0 -DdevelopmentVersion=1.3.0-SNAPSHOT
-```
-
-`release:prepare` does GitHub tags and commits, while `release:perform` signs the artifacts and uploads them to the staging repositoring on [https://oss.sonatype.org](https://oss.sonatype.org).
-
-After that, manually verify the uploaded artifacts on [https://oss.sonatype.org/#stagingRepositories](https://oss.sonatype.org/#stagingRepositories), click `Close` to trigger Sonatype's verification, and then `Release`.
-
-Create a commit to remove dependencies from the build (undoing the first step):
-
-* Comment out the `prometheus-metrics-shaded-dependencies` module to the root `pom.xml`.
-* Change the versions of the shaded dependencies to the latest released version on Maven Central in `prometheus-metrics-exporter-opentelemetry`, `prometheus-metrics-exposition-formats`, and `prometheus-metrics-bom`.
-

Subject: [PATCH 258/870] Use buffered writer (#1241)

Without buffered reader, every single output character through given stack goes to "StreamEncoder public void write(int c)" and single element char array is created.
It makes pressure to GC and CPU
BufferedReader reduce the pressure

write:130, StreamEncoder (sun.nio.cs)
write:201, OutputStreamWriter (java.io)
writeMetadata:338, PrometheusTextFormatWriter (io.prometheus.metrics.expositionformats)
writeGauge:129, PrometheusTextFormatWriter (io.prometheus.metrics.expositionformats)
write:68, PrometheusTextFormatWriter (io.prometheus.metrics.expositionformats)
write:48, PrometheusOutputFormat$1 (org.springframework.boot.actuate.metrics.export.prometheus)
scrape:87, PrometheusScrapeEndpoint (org.springframework.boot.actuate.metrics.export.prometheus)

StreamEncoder public void write(int c) throws IOException {
  char[] cbuf = new char[1];
  cbuf[0] = (char) c;

+title: Caffeine Cache
+weight: 1
+---
+
+The Caffeine instrumentation module, added in version 1.3.2, translates observability data
+provided by caffeine `Cache` objects into prometheus metrics.
+
+{{< tabs "uniqueid" >}}
+{{< tab "Gradle" >}}

+    prometheus-metrics-instrumentation-caffeine
+    1.3.2
+
+```
+{{< /tab >}}
+{{< /tabs >}}
+
+In order to collect metrics:
+
+ * A single `CacheMetricsCollector` instance must be registered with the registry;
+   * Multiple `CacheMetricsCollector` instances cannot be registered with the same registry;
+ * The `Cache` object must be instantiated with the `recordStats()` option, and then added to the
+   `CacheMetricsCollector` instance with a unique name, which will be used as the value of the
+   `cache` label on the exported metrics;
+   * If the `recordStats` option is not set, most metrics will only return zero values;
+
+```java
+var cache = Caffeine.newBuilder().recordStats().build();
+var cacheMetrics = CacheMetricsCollector.builder().build();
+PrometheusRegistry.defaultRegistry.register(cacheMetrics);
+cacheMetrics.addCache("mycache", cache);
+```
+
+{{< hint type=note >}}
+
+In version 1.3.5 and older of the caffeine instrumentation library, `CacheMetricsCollector.builder`
+does not exist, i.e. a constructor call `new CacheMetricsCollector()` is the only option.
+
+{{< /hint >}}
+
+All example metrics on this page will use the `mycache` label value.
+
+Generic Cache Metrics
+---------------------
+
+For all cache instances, the following metrics will be available:
+
+```
+# TYPE caffeine_cache_hit counter
+# HELP caffeine_cache_hit Cache hit totals
+caffeine_cache_hit_total{cache="mycache"} 10.0
+# TYPE caffeine_cache_miss counter
+# HELP caffeine_cache_miss Cache miss totals
+caffeine_cache_miss_total{cache="mycache"} 3.0
+# TYPE caffeine_cache_requests counter
+# HELP caffeine_cache_requests Cache request totals, hits + misses
+caffeine_cache_requests_total{cache="mycache"} 13.0
+# TYPE caffeine_cache_eviction counter
+# HELP caffeine_cache_eviction Cache eviction totals, doesn't include manually removed entries
+caffeine_cache_eviction_total{cache="mycache"} 1.0
+# TYPE caffeine_cache_estimated_size
+# HELP caffeine_cache_estimated_size Estimated cache size
+caffeine_cache_estimated_size{cache="mycache"} 5.0
+```
+
+Loading Cache Metrics
+---------------------
+
+If the cache is an instance of `LoadingCache`, i.e. it is built with a `loader` function that is
+managed by the cache library, then metrics for observing load time and load failures become
+available:
+
+```
+# TYPE caffeine_cache_load_failure counter
+# HELP caffeine_cache_load_failure Cache load failures
+caffeine_cache_load_failure_total{cache="mycache"} 10.0
+# TYPE caffeine_cache_loads counter
+# HELP caffeine_cache_loads Cache loads: both success and failures
+caffeine_cache_loads_total{cache="mycache"} 3.0
+# TYPE caffeine_cache_load_duration_seconds summary
+# HELP caffeine_cache_load_duration_seconds Cache load duration: both success and failures
+caffeine_cache_load_duration_seconds_count{cache="mycache"} 7.0
+caffeine_cache_load_duration_seconds_sum{cache="mycache"} 0.0034
+```
+
+Weighted Cache Metrics
+----------------------
+
+Two metrics exist for observability specifically of caches that define a `weigher`:
+
+```
+# TYPE caffeine_cache_eviction_weight counter
+# HELP caffeine_cache_eviction_weight Weight of evicted cache entries, doesn't include manually removed entries
+caffeine_cache_eviction_weight_total{cache="mycache"} 5.0
+# TYPE caffeine_cache_weighted_size gauge
+# HELP caffeine_cache_weighted_size Approximate accumulated weight of cache entries
+caffeine_cache_weighted_size{cache="mycache"} 30.0
+```
+
+{{< hint type=note >}}
+
+`caffeine_cache_weighted_size` is available only if the cache instance defines a `maximumWeight`.
+
+{{< /hint >}}
+
+Up to version 1.3.5 and older, the weighted metrics had a different behavior:
+
+ * `caffeine_cache_weighted_size` was not implemented;
+ * `caffeine_cache_eviction_weight` was exposed as a `gauge`;
+
+It is possible to restore the behavior of version 1.3.5 and older, by either:
+
+ * Using the deprecated `new CacheMetricsCollector()` constructor;
+ * Using the flags provided on the `CacheMetricsCollector.Builder` object to opt-out of each of the
+   elements of the post-1.3.5 behavior:
+   * `builder.collectWeightedSize(false)` will disable collection of `caffeine_cache_weighted_size`;
+   * `builder.collectEvictionWeightAsCounter(false)` will expose `caffeine_cache_eviction_weight` as
+     a `gauge` metric;

Subject: [PATCH 282/870] Use bulk string writes for text formats (#1273)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Further optimize `TextFormatUtil#writeEscapedLabelValue`. We're seeing
`TextFormatUtil#writeEscapedLabelValue` show up in our production traces
due to the single `char` writes to `OutputStreamWriter`. We're using
`OpenMetricsTextFormatWriter`. #1241 and #1248 should take care of most
of these issues but there still remains some optimization potential
left. `BufferedWriter#write(int)` has some minimal overhead in terms of
locking. If we assume that rarely any characters need to be escaped and
instead optimize to write as large of a part of the String as possible
in one method call.

Before
---------
```
Benchmark                                             Mode  Cnt       Score      Error  Units
TextFormatUtilBenchmark.openMetricsWriteToByteArray  thrpt   25  438485.372 ± 4270.355  ops/s
TextFormatUtilBenchmark.openMetricsWriteToNull       thrpt   25  440105.281 ± 2891.572  ops/s
TextFormatUtilBenchmark.prometheusWriteToByteArray   thrpt   25  467213.001 ±  878.780  ops/s
TextFormatUtilBenchmark.prometheusWriteToNull        thrpt   25  472931.759 ±  976.028  ops/s
```

After
-------

```
Benchmark                                             Mode  Cnt       Score      Error  Units
TextFormatUtilBenchmark.openMetricsWriteToByteArray  thrpt   25  462852.243 ± 5071.696  ops/s
TextFormatUtilBenchmark.openMetricsWriteToNull       thrpt   25  469910.681 ± 1670.430  ops/s
TextFormatUtilBenchmark.prometheusWriteToByteArray   thrpt   25  482362.506 ± 2051.684  ops/s
TextFormatUtilBenchmark.prometheusWriteToNull        thrpt   25  487707.557 ± 3344.881  ops/s
```

About a 5% to 6% gain for `OpenMetricsTextFormatWriter` and around 3%
for `PrometheusTextFormatWriter`.

Note that this benchmark is actually for `OpenMetricsTextFormatWriter`
and `PrometheusTextFormatWriter` since `TextFormatUtil` is not public
and can therefore not be benchmarked directly. The relative gains in
`#writeEscapedLabelValue` are higher because the benchmark runs the full
text format writers.

I also added a test for `TextFormatUtil#writeEscapedLabelValue` since
the code is now more complicated.

Subject: [PATCH 287/870] Bump org.awaitility:awaitility from 4.2.2 to 4.3.0
 (#1286)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bumps
[org.awaitility:awaitility](https://github.com/awaitility/awaitility)
from 4.2.2 to 4.3.0.

    
Changelog

    Sourced from org.awaitility:awaitility's
changelog.
    

    

    Changelog 4.3.0 (2025-02-21)
    

      

    • 

      Support for kotlin.time.Duration in Kotlin DSL (thanks to Ivo Šmíd
for PR)
      

      • 

    • 

      Upgraded kotlin version in the awaitility-kotlin module to 2.1.10
      

      • 

    • 

      Using a more descriptive error message when using VERY long wait
conditions or poll durations (issue 290)
      

      • 

    • 

      Added an overloaded method of untilAsserted(..) that takes a supplier
and a consumer. Example lets say you have a class like this:
public class MyClass {
public String myFunction() {
// Imagine stuff being executed in asynchrinously here and the result of
this
// operation is a string called "my value"
return "my value"
}
}
      

      // Then in your test you can wait for the "myFunction" to
be asserted by a "consumer" that uses
// assertj to make sure that "myFunction" returns
""my value"
await().untilAsserted(myClass::myFunction, value ->
Assertions.assertThat(value).isEqualTo("my value"));

Bumps [com.google.guava:guava](https://github.com/google/guava) from
33.4.0-jre to 33.4.5-jre.

    
Release notes

    Sourced from com.google.guava:guava's
releases.
    

    

    33.4.5
    

    For those upgrading from Guava 33.4.0 or earlier, be sure to read the release
notes for Guava 33.4.1.
    

    Maven
    

    <dependency>
  <groupId>com.google.guava</groupId>
  <artifactId>guava</artifactId>
  <version>33.4.5-jre</version>
  <!-- or, for Android: -->
  <version>33.4.5-android</version>

    Changelog
    

      

    • Changed the Guava jar (plus guava-testlib and failureaccess
jars) to be a modular jar. (7a71ea0bfa, 287c701a86)
      • 

    • Changed various classes to stop using sun.misc.Unsafe
under Java 9+. (ee63055ddd, 80aab00dc5b7a36785f5e09b6a54397388980cde,
400af25292096746ed3f6164f0ff88209acbb19f,
71d0692d418a5dd001c9b3786275a5f1f94e1971,
d1a3cd5037528a2ae990bfceed9cdd009fbc54de,
b3bb29a54b8f13d6f6630b6cb929867adbf6b9a0,
1a300f6b2f7ba03ae9bc3620a80c4d4589c65b69)

        

      • Note that, if you use guava-android on the JVM (instead
of using guava-jre), Guava will still try to use
sun.misc.Unsafe. We will do further
work on this in the future.
        • 

      

      • 

    • Belatedly updated the Public Suffix List data.
(ee3b9c64382037f72b3a8341915cc64b87850b53,
d25d62fc843ece1c3866859bc8639b815093eac8)
      • 

    

    Special thanks to @​sgammon for his modularization efforts.
    

    33.4.4
    

    This is one of a series of releases that improve Guava's nullness
annotations. For more information, including troubleshooting help, see
the
release notes for Guava 33.4.1. Most users can update directly to
Guava 33.4.5.

Subject: [PATCH 313/870] Bump com.google.errorprone:error_prone_core from
 2.36.0 to 2.37.0 (#1311)

Bumps
[com.google.errorprone:error_prone_core](https://github.com/google/error-prone)
from 2.36.0 to 2.37.0.

    
Release notes

    Sourced from com.google.errorprone:error_prone_core's
releases.
    

    

    Error Prone 2.37.0
    

    Changes:
    

      

    • The annotations that were previously in
error_prone_type_annotations have been been merged into
error_prone_annotations.
error_prone_type_annotations is now deprecated, and will be
removed in a future release.
      • 

    

    New checks:
    

      

    • AssignmentExpression
- The use of an assignment expression can be surprising and hard to
read; consider factoring out the assignment to a separate
statement.
      • 

    • IntFloatConversion
- Detect calls to scalb that should be using the double
overload instead
      • 

    • InvalidSnippet
- Detects snippets which omit the : required for inline
code.
      • 

    • JUnit4EmptyMethods
- Detects empty JUnit4 @Before, @After,
@BeforeClass, and @AfterClass methods.
      • 

    • MockIllegalThrows
- Detects cases where Mockito is configured to throw checked exception
types which are impossible.
      • 

    • NegativeBoolean
- Prefer positive boolean names.
      • 

    • RuleNotRun
- Detects TestRules not annotated with @Rule,
that won't be run.
      • 

    • StringConcatToTextBlock
- Replaces concatenated multiline strings with text blocks.
      • 

    • TimeInStaticInitializer
- Detects accesses of the system time in static contexts.
      • 

    

    Closed issues:
    

      

    • Propagate check flags in patch mode (#4699)

      • 

    • FloatingPointAssertionWithinEpsilonTest depends on default locale
(#4815)
      • 

    • @InlineMe patching of Strings.repeat
produces broken code (#4819)
      • 

    • Fix a crash in IdentifierName on unnamed (_) variables

Subject: [PATCH 315/870] Bump com.google.guava:guava from 33.4.5-jre to
 33.4.6-jre (#1313)

Bumps [com.google.guava:guava](https://github.com/google/guava) from
33.4.5-jre to 33.4.6-jre.

    
Release notes

    Sourced from com.google.guava:guava's
releases.
    

    

    33.4.6
    

    Guava 33.4.6 fixes two problems that we introduced while modularizing
Guava in 33.4.5.
    

    Even if you're not upgrading from Guava 33.4.0 or earlier, still read
the
release notes for Guava 33.4.1. Those release notes contain
information about Guava 33.4.5 and 33.4.6's effect on the module
system.
    

    Maven
    

    <dependency>
  <groupId>com.google.guava</groupId>
  <artifactId>guava</artifactId>
  <version>33.4.6-jre</version>
  <!-- or, for Android: -->
  <version>33.4.6-android</version>
</dependency>

    

    Jar files
    


    Guava requires one
runtime dependency, which you can download here:
    


    Javadoc
    


    JDiff
    


    Changelog
    

      

    • Removed the extra copy of each class from the Guava jar. The extra
copies were an accidental addition from the modularization work in Guava
33.4.5. (40485b93ce)
      • 

    • Fixed annotation-related warnings when using Guava in modular
builds. The most common such warning is Cannot find annotation
method 'value()' in type 'DoNotMock': .... (7e15ab3566)
      •

Subject: [PATCH 326/870] Bump com.google.guava:guava from 33.4.6-jre to
 33.4.7-jre (#1323)

Bumps [com.google.guava:guava](https://github.com/google/guava) from
33.4.6-jre to 33.4.7-jre.

    
Release notes

    Sourced from com.google.guava:guava's
releases.
    

    

    33.4.7
    

    Known issue: This release breaks the
build of Android apps with a minSdkVersion below 26. We will publish
a fixed version soon. Sorry again for the continuing trouble.
    

    Guava 33.4.7, like 33.4.6,
fixes two problems that we introduced while modularizing Guava and
migrating off Unsafe in 33.4.5.
    

    Even if you're not upgrading from Guava 33.4.0 or earlier, still read
the
release notes for Guava 33.4.1. Those release notes contain
information about the effects of Guava 33.4.5 and higher on the module
system.
    

    Maven
    

    <dependency>
  <groupId>com.google.guava</groupId>
  <artifactId>guava</artifactId>
  <version>33.4.7-jre</version>
  <!-- or, for Android: -->
  <version>33.4.7-android</version>
</dependency>

    

    Jar files
    


    Guava requires one
runtime dependency, which you can download here:
    


    Javadoc
    


    JDiff
    


    Changelog
    

      

    • Modified the guava module's dependency on
failureaccess to be transitive. Also, modified
the guava-testlib module to make its dependency on
guava transitive, to remove its dependency on
failureaccess, and to add a dependency
(transitive) on junit. (63ecdf2239)
      • 

    • util.concurrent: Modified our fast paths to ensure that
they continue to work when run through optimizers, such as those
commonly used by Android apps. This fixes problems that some users may
have seen since Guava
33.4.5. (b8dcaede09bcf1c3bd5fc037690498f6ac560c54, f9eff73b8d)
      • 

    • util.concurrent: Changed the guava-android
copy of AbstractFuture to try VarHandle before
Unsafe, eliminating a warning under newer JDKs.

Subject: [PATCH 332/870] Bump com.google.guava:guava from 33.4.7-jre to
 33.4.8-jre (#1330)

Bumps [com.google.guava:guava](https://github.com/google/guava) from
33.4.7-jre to 33.4.8-jre.

    
Release notes

    Sourced from com.google.guava:guava's
releases.
    

    

    33.4.8
    

    Guava 33.4.8 fixes a problem that we introduced while starting to
migrate guava-android off Unsafe in 33.4.7.
    

    Even if you're not upgrading from Guava 33.4.0 or earlier, still read
the
release notes for Guava 33.4.1. Those release notes contain
information about the effects of Guava 33.4.5 and higher on the module
system.

  <!-- or, for Android: -->
  <version>33.4.8-android</version>
</dependency>

    Guava requires one
runtime dependency, which you can download here:

    Changelog
    

      

    • util.concurrent: Removed our VarHandle
code from guava-android. While the code was never used at
runtime under Android, it was causing problems
under the Android Gradle Plugin with a minSdkVersion
below 26. To continue to avoid sun.misc.Unsafe under the
JVM, guava-android will now always use
AtomicReferenceFieldUpdater when run there.

 ## What Prometheus Java client optimizes for
 
 concurrent updates of metrics in multi-threaded applications.
-If your application is single-threaded and uses only one processor core, your application isn't performance critical anyway.
-If your application is designed to use all available processor cores for maximum performance, then you want a metric library that doesn't slow your application down.
-Prometheus client Java metrics support concurrent updates and scrapes. This shows in benchmarks with multiple threads recording data in shared metrics.

+This is the documentation for the
+[Prometheus Java client library](https://github.com/prometheus/client_java)
+version 1.0.0 and higher.
 
 The main new features of the 1.0.0 release are:
 
-* **Prometheus native histograms:** Support for the new Prometheus histogram type.
-* **OpenTelemetry Exporter:** Push metrics in OTLP format to an OpenTelemetry endpoint.
-* **Runtime configuration:** Configure metrics, exporters, and more at runtime using a properties file or system properties.

 **Documentation and Examples**
 
-In addition to this documentation page we created an [examples/](https://github.com/prometheus/client_java/tree/main/examples) directory with end-to-end scenarios (Docker compose) illustrating new features.

 **Performance Benchmarks**
 
-Initial performance benchmarks are looking great: All core metric types (including native histograms) allow concurrent updates, so if you instrument a performance critical Web service that utilizes all processor cores in parallel the metrics library will not introduce additional synchronization. See Javadoc comments in [benchmarks/](https://github.com/prometheus/client_java/tree/main/benchmarks) for benchmark results.

 **For users of the 0.16.0 version and older**
 
-Updating to the 1.0.0 version is a breaking change. However, there's a `prometheus-metrics-simpleclient-bridge` module available that allows you to use your existing simpleclient 0.16.0 metrics with the new 1.0.0 `PrometheusRegistry`. So you don't need to upgrade your instrumentation code, you can keep using your existing metrics. See the [compatibility > simpleclient](https://prometheus.github.io/client_java/migration/simpleclient/) in the menu on the left.

-* System property `-Dprometheus.config=/path/to/prometheus.properties`.
-* Environment variable `PROMETHEUS_CONFIG=/path/to/prometheus.properties`.

It is very common to sample only 10% of traces and discard 90%. However, this can be an issue with Exemplars: In 90% of the cases Exemplars would point to a trace that has been thrown away.

Root cause: Renovate was detecting the dependency but not creating PRs due to the default ignoreUnstable behavior in the recommended preset. Since this package only publishes alpha versions, we need to explicitly allow unstable version updates. Solution: Added a packageRule with ignoreUnstable: false for this specific package to ensure Renovate will create PRs for newer alpha versions. --------- Signed-off-by: Gregor Zeitlinger --- .github/renovate.json5 | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/.github/renovate.json5 b/.github/renovate.json5 index bcf6643d1..8ded8e186 100644 --- a/.github/renovate.json5 +++ b/.github/renovate.json5 @@ -23,6 +23,10 @@ groupName: "java graalvm", additionalBranchPrefix: "graalvm-", }, + { + matchPackageNames: ["io.opentelemetry.instrumentation:opentelemetry-instrumentation-bom-alpha"], + ignoreUnstable: false, + }, ], customManagers: [ { From 04bc727fcb2b9ba4da8eb7268c562f5385f5eda4 Mon Sep 17 00:00:00 2001 From: "renovate[bot]" <29139614+renovate[bot]@users.noreply.github.com> Date: Mon, 9 Feb 2026 17:53:18 +0000 Subject: [PATCH 804/870] fix(deps): update dependency io.opentelemetry.instrumentation:opentelemetry-instrumentation-bom-alpha to v2.24.0-alpha (#1863) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This PR contains the following updates: | Package | Change | [Age](https://docs.renovatebot.com/merge-confidence/) | [Confidence](https://docs.renovatebot.com/merge-confidence/) | |---|---|---|---| | [io.opentelemetry.instrumentation:opentelemetry-instrumentation-bom-alpha](https://redirect.github.com/open-telemetry/opentelemetry-java-instrumentation) | `2.16.0-alpha` → `2.24.0-alpha` | ![age](https://developer.mend.io/api/mc/badges/age/maven/io.opentelemetry.instrumentation:opentelemetry-instrumentation-bom-alpha/2.24.0-alpha?slim=true) | ![confidence](https://developer.mend.io/api/mc/badges/confidence/maven/io.opentelemetry.instrumentation:opentelemetry-instrumentation-bom-alpha/2.16.0-alpha/2.24.0-alpha?slim=true) | --- > [!WARNING] > Some dependencies could not be looked up.

825/870] ci: replace linting setup with flint (#1883) ## Summary - Replace the custom super-linter setup with [flint](https://github.com/grafana/flint) v0.4.0, which provides shared, maintained lint tasks (super-linter, link checking, renovate-deps) - Use flint's Renovate shareable preset for custom managers instead of inline config - Remove manual URL remap step from lint workflow (now handled by flint's links.sh) - Add `lint:renovate-deps` task to verify tracked Renovate dependencies - Move release-please config and manifest into `.github/config/` - Add PR title linting workflow (`action-semantic-pull-request`) ## Test plan - [ ] CI passes (lint, build, tests) - [ ] Release-please workflow still triggers correctly with moved config - [ ] PR title lint workflow runs on new PRs

After applying this change locally, I ran the [quick test](https://github.com/prometheus/jmx_exporter/blob/main/run-quick-test.sh) a few times and the error was no longer present. --------- Signed-off-by: Jay DeLuca --- .../otelmodel/MetricDataFactory.java | 24 +++++++++++++++++++ .../exporter/opentelemetry/ExportTest.java | 22 ++++++++++++++++- 2 files changed, 45 insertions(+), 1 deletion(-) diff --git a/prometheus-metrics-exporter-opentelemetry/src/main/java/io/prometheus/metrics/exporter/opentelemetry/otelmodel/MetricDataFactory.java b/prometheus-metrics-exporter-opentelemetry/src/main/java/io/prometheus/metrics/exporter/opentelemetry/otelmodel/MetricDataFactory.java index 4c75d2622..78ecb0ebe 100644 --- a/prometheus-metrics-exporter-opentelemetry/src/main/java/io/prometheus/metrics/exporter/opentelemetry/otelmodel/MetricDataFactory.java +++ b/prometheus-metrics-exporter-opentelemetry/src/main/java/io/prometheus/metrics/exporter/opentelemetry/otelmodel/MetricDataFactory.java @@ -27,7 +27,11 @@ public MetricDataFactory( this.currentTimeMillis = currentTimeMillis;

    jdx/mise (mise) ### [`v2026.2.24`](https://redirect.github.com/jdx/mise/releases/tag/v2026.2.24): : Hooks get Tera templates, aqua cache cleanup, and better error messages [Compare Source](https://redirect.github.com/jdx/mise/compare/v2026.2.23...v2026.2.24) A bug-fix release that enables Tera template rendering in hooks, eliminates a class of stale PATH bugs with aqua tools, improves error messages for unsupported registry tools, and removes the long-deprecated `python.venv_auto_create` setting. #### Fixed - **Hooks now support Tera template rendering** -- Hook scripts can now use Tera template variables like `{{tools.ripgrep.path}}`, just like tasks. Additionally, the install progress bar is now cleared before postinstall hooks run, so hook output is no longer masked by the progress UI. Preinstall hooks correctly skip `tools=true` env directives since referenced tools may not yet be installed. [#​8385](https://redirect.github.com/jdx/mise/pull/8385) by [@​jdx](https://redirect.github.com/jdx) - **Aqua tool PATH entries no longer go stale** -- The aqua backend's `bin_paths` disk cache (`bin_paths.msgpack.z`) has been removed entirely. This cache provided negligible performance benefit -- reading and decompressing a msgpack file is comparable to parsing the small YAML registry entry -- but was the root cause of stale PATH entries after tool installs (e.g. upgrading `uv` causing its PATH entry to vanish). The previous fix in v2026.2.23 was raceable by concurrent `mise hook-env` calls; removing the cache eliminates this class of bugs completely. [#​8383](https://redirect.github.com/jdx/mise/pull/8383) by [@​jdx](https://redirect.github.com/jdx) - **Better error when a registry tool has no supported backends** -- When a tool exists in the registry but all its backends are filtered out for the current platform or configuration (e.g. `imagemagick` on a platform where only `conda` and `asdf` backends are registered but disabled), the error now clearly explains the situation and lists the registered backends instead of suggesting the user meant the exact tool name they already typed. [#​8388](https://redirect.github.com/jdx/mise/pull/8388) by [@​jdx](https://redirect.github.com/jdx) #### Removed - **Deprecated `python.venv_auto_create` setting removed** -- The `python.venv_auto_create` and `python_venv_auto_create` settings have been fully removed. These were deprecated in favor of the `_.python.venv` configuration. If you were relying on the legacy `virtualenv` tool option to auto-create venvs, mise will now warn and print manual creation instructions instead. Migrate to the newer venv configuration: [#​8384](https://redirect.github.com/jdx/mise/pull/8384) by [@​jdx](https://redirect.github.com/jdx) ```toml [tools] python = { version = "3.12", _.python.venv = { path = ".venv", create = true } } ``` #### Breaking Changes - The `python.venv_auto_create` and `python_venv_auto_create` settings no longer exist. If you still have these in your configuration, they will be silently ignored. Use `_.python.venv = { path = ".venv", create = true }` in your tool configuration instead. [#​8384](https://redirect.github.com/jdx/mise/pull/8384) **Full Changelog**: ### [`v2026.2.23`](https://redirect.github.com/jdx/mise/releases/tag/v2026.2.23): : Stricter lockfile enforcement and vfox backend options [Compare Source](https://redirect.github.com/jdx/mise/compare/v2026.2.22...v2026.2.23) This release tightens lockfile behavior in `--locked` mode, fixes a stale PATH cache issue with aqua-based tools, resolves intermittent panics with remote git tasks, and adds the ability to pass custom options to vfox backend plugins. #### Added - **Custom options for vfox backend plugins** -- Options defined in `mise.toml` tool entries are now passed through to vfox backend plugins in both `BackendInstall` and `BackendExecEnv` contexts, accessible in Lua via `ctx.options`. This enables custom plugin use cases like controlling build parameters. [#​8369](https://redirect.github.com/jdx/mise/pull/8369) by [@​Attempt3035](https://redirect.github.com/Attempt3035) ```toml [tools] "llvm:clang" = { version = "latest", build_cores = "22" } ``` ```lua function PLUGIN:BackendInstall(ctx) local cores = ctx.options.build_cores -- use cores in your build logic end ``` - **Registry: porter** -- Added [Porter](https://porter.sh), a CNAB bundle authoring and management tool (`github:getporter/porter`). [#​8380](https://redirect.github.com/jdx/mise/pull/8380) by [@​lbergnehr](https://redirect.github.com/lbergnehr) - **Registry: entire** -- Added entire CLI (`aqua:entireio/cli`). [#​8378](https://redirect.github.com/jdx/mise/pull/8378) by [@​TyceHerrman](https://redirect.github.com/TyceHerrman) - **Registry: topgrade** -- Added topgrade (`aqua:topgrade-rs/topgrade`), an all-in-one system upgrade tool. [#​8377](https://redirect.github.com/jdx/mise/pull/8377) by [@​TyceHerrman](https://redirect.github.com/TyceHerrman) #### Fixed - **`--locked` mode now strictly enforces the lockfile** -- Previously, `mise lock` could still run while `--locked` was active, `mise use tool@latest` could bypass the lockfile, and tools missing from the lockfile would silently fall through to remote resolution. Now `mise lock` refuses to run in locked mode with a clear error and hint, `mise use tool@latest` respects the lockfile when locked, and missing tools fail fast with an actionable message instead of resolving remotely. [#​8362](https://redirect.github.com/jdx/mise/pull/8362) by [@​jdx](https://redirect.github.com/jdx) - **Aqua tool PATH entries no longer go missing after install** -- The `list_bin_paths()` cache could be populated with stale (empty) data before extraction finished, or by a concurrent `mise hook-env` call during installation. The in-memory and on-disk `bin_paths` caches are now cleared after an aqua tool install completes so paths are recomputed from the freshly installed files. Fixes an issue where upgrading tools like `uv` caused their PATH entry to vanish. [#​8374](https://redirect.github.com/jdx/mise/pull/8374) by [@​jdx](https://redirect.github.com/jdx) - **Remote git task cache no longer panics or corrupts on concurrent access** -- Replaced `println!`/`eprintln!` with non-panicking `writeln!` to handle EPIPE gracefully, and added file locking with clone-to-temp-then-rename to prevent concurrent cache corruption when multiple mise processes fetch the same remote git task simultaneously. [#​8375](https://redirect.github.com/jdx/mise/pull/8375) by [@​vmaleze](https://redirect.github.com/vmaleze) #### New Contributors - [@​Attempt3035](https://redirect.github.com/Attempt3035) made their first contribution in [#​8369](https://redirect.github.com/jdx/mise/pull/8369) - [@​lbergnehr](https://redirect.github.com/lbergnehr) made their first contribution in [#​8380](https://redirect.github.com/jdx/mise/pull/8380) **Full Changelog**: ### [`v2026.2.22`](https://redirect.github.com/jdx/mise/releases/tag/v2026.2.22): : Outdated plugins, rename_exe fixes, and smoother installs [Compare Source](https://redirect.github.com/jdx/mise/compare/v2026.2.21...v2026.2.22) A small release adding a new way to check for outdated plugins, along with three bug fixes for archive installs, tool environment resolution, and cross-platform Ruby lockfiles. #### Added - **`mise plugins ls --outdated` flag** -- A new `-o`/`--outdated` flag checks remote git refs in parallel and displays only plugins where the local SHA differs from the remote. Shows a table with plugin name, URL, ref, local SHA, and remote SHA. Prints "All plugins are up to date" when everything is current. [#​8360](https://redirect.github.com/jdx/mise/pull/8360) by [@​jdx](https://redirect.github.com/jdx) ```sh $ mise plugins ls --outdated Plugin Url Ref Local Remote tiny https://github.com/mise-plugins/rtx-tiny.git main abc1234 def5678 ``` #### Fixed - **`rename_exe` works with archives containing a `bin/` subdirectory** -- When an archive extracts to a layout like `prefix/bin/binary`, the `rename_exe` option was silently skipped because it searched the extraction root non-recursively instead of the `bin/` subdirectory where the binary actually lives. Both the GitHub-style backend and the HTTP backend now auto-detect the `bin/` subdirectory as the search directory, matching the same logic used by `discover_bin_paths()` for PATH construction. [#​8358](https://redirect.github.com/jdx/mise/pull/8358) by [@​jdx](https://redirect.github.com/jdx) - **Installing cargo/npm/pipx tools no longer crashes with `tools = true` env directives** -- When `[env]` contained entries like `NODE_VERSION = { value = "{{ tools.node.version }}", tools = true }`, installing npm/cargo/pipx tools would fail with "Variable not found in context" because the referenced tools might not be installed yet. The cargo, npm, and pipx backends now skip `tools = true` env directive resolution during installation while still including tool paths in PATH. [#​8356](https://redirect.github.com/jdx/mise/pull/8356) by [@​jdx](https://redirect.github.com/jdx) - **Ruby lockfile resolves correct Windows checksums** -- Running `mise lock` on macOS/Linux now correctly resolves RubyInstaller2 binary URLs and checksums for Windows platform entries, instead of incorrectly using the MRI source tarball checksum. The lockfile generator now fetches the correct `.7z` asset from the `oneclick/rubyinstaller2` GitHub releases for Windows targets. [#​8357](https://redirect.github.com/jdx/mise/pull/8357) by [@​jdx](https://redirect.github.com/jdx) #### Changed - **Registry: terradozer switched to GitHub fork** -- The terradozer registry entry now points to `github:chenrui333/terradozer` (replacing the archived asdf plugin and unavailable aqua backend), and is restricted to Linux and macOS. [#​8365](https://redirect.github.com/jdx/mise/pull/8365) by [@​chenrui333](https://redirect.github.com/chenrui333) #### New Contributors - [@​chenrui333](https://redirect.github.com/chenrui333) made their first contribution in [#​8365](https://redirect.github.com/jdx/mise/pull/8365) **Full Changelog**: ### [`v2026.2.21`](https://redirect.github.com/jdx/mise/releases/tag/v2026.2.21): : Bug fix roundup for monorepo tasks, conda noarch, and exec PATH handling [Compare Source](https://redirect.github.com/jdx/mise/compare/v2026.2.20...v2026.2.21) A bug-fix release addressing several regressions and long-standing issues: monorepo task variables and glob dependencies now resolve correctly, the conda backend can install Python noarch packages, `mise x` respects virtualenv PATH ordering again, and nested task execution no longer hangs. #### Fixed - **`mise x` respects virtualenv PATH order again** -- A pre-resolution step added in v2026.2.17 ([#​8276](https://redirect.github.com/jdx/mise/pull/8276)) resolved bare command names directly to mise-managed tool paths, bypassing PATH entirely. This broke `_.python.venv` and similar configs where a virtualenv binary should take precedence over the mise-managed install. The pre-resolution is removed; shim stripping in `exec_program` (also from [#​8276](https://redirect.github.com/jdx/mise/issues/8276)) is sufficient to prevent recursion. [#​8342](https://redirect.github.com/jdx/mise/pull/8342) by [@​jdx](https://redirect.github.com/jdx) - **Conda noarch Python packages install correctly** -- Installing noarch Python packages via the conda backend (e.g. `mise use conda:ruff`) failed because the linker didn't know the Python version needed to compute `site-packages` paths. The solver's resolved Python version is now extracted and passed through to `link_package`, fixing the error. [#​8349](https://redirect.github.com/jdx/mise/pull/8349) by [@​wolfv](https://redirect.github.com/wolfv) - **Nested mise tasks no longer hang** -- The process group isolation (`setpgid`/`killpg`) introduced in v2026.2.18 and refined in v2026.2.19 has been fully reverted. When tools like Playwright use process-group-based kills (`kill(-pid, SIGKILL)`) to tear down a server subprocess tree, grandchild processes in a separate group (created by mise's `setpgid`) survived and held pipes open, causing indefinite hangs. mise now sends signals directly to child PIDs instead. [#​8347](https://redirect.github.com/jdx/mise/pull/8347) by [@​jdx](https://redirect.github.com/jdx) - **Monorepo tasks resolve `[vars]` from subdirectory configs** -- Running a monorepo task like `mise run //infra/stacks/gcp:greet` failed to pick up `[vars]` defined in subdirectory `.mise.toml` files, causing template rendering errors. Variables are now resolved from the task's full config hierarchy (including `mise..toml` overlays) and threaded through script rendering. [#​8343](https://redirect.github.com/jdx/mise/pull/8343) by [@​jdx](https://redirect.github.com/jdx) - **Monorepo glob dependencies trigger subdirectory prepare steps** -- When a root task depended on a monorepo glob pattern like `//...:check`, the prepare phase only collected configs from top-level tasks, missing subdirectory tasks entirely. Dependencies are now resolved before prepare runs, so transitive subdirectory tasks and their prepare providers are properly discovered. [#​8353](https://redirect.github.com/jdx/mise/pull/8353) by [@​jdx](https://redirect.github.com/jdx) #### New Contributors - [@​wolfv](https://redirect.github.com/wolfv) made their first contribution in [#​8349](https://redirect.github.com/jdx/mise/pull/8349) **Full Changelog**: ### [`v2026.2.20`](https://redirect.github.com/jdx/mise/releases/tag/v2026.2.20): : Conda rewrite, .NET SDK core plugin, and per-task timeouts [Compare Source](https://redirect.github.com/jdx/mise/compare/v2026.2.19...v2026.2.20) A feature-packed release that replaces the conda backend with production-grade internals, adds a native .NET SDK plugin, and finally enforces per-task timeouts. Several lockfile and environment-handling fixes round things out. #### Highlights - **Conda backend rewritten with rattler** -- The experimental conda backend has been completely rewritten to use the [rattler](https://redirect.github.com/conda/rattler) Rust crates (the same engine behind pixi), replacing \~1,600 lines of custom code that relied on the unsupported anaconda.org API. This brings a proper SAT-based dependency solver, correct binary prefix replacement, and repodata caching via CDN. [#​8325](https://redirect.github.com/jdx/mise/pull/8325) by [@​jdx](https://redirect.github.com/jdx) - **Native .NET SDK management** -- A new core plugin for .NET SDK installs all versions side-by-side under a shared `DOTNET_ROOT`, matching .NET's native multi-version model. It uses Microsoft's official `dotnet-install` script and supports `global.json` for per-project SDK pinning. [#​8326](https://redirect.github.com/jdx/mise/pull/8326) by [@​jdx](https://redirect.github.com/jdx) - **Per-task timeouts are now enforced** -- The `timeout` field on tasks (added in v2025.1.6 but never wired up) now actually kills tasks that exceed their limit. Timeouts send SIGTERM with a 5-second grace period before SIGKILL, and both per-task and global `task_timeout` settings are respected. [#​8250](https://redirect.github.com/jdx/mise/pull/8250) by [@​tvararu](https://redirect.github.com/tvararu) #### Added - **Core .NET SDK plugin** -- `mise use dotnet@8` now installs via a native core plugin with side-by-side version support and `global.json` detection. Configure `DOTNET_ROOT` via the new `dotnet.dotnet_root` setting. [#​8326](https://redirect.github.com/jdx/mise/pull/8326) by [@​jdx](https://redirect.github.com/jdx) - **Per-task timeout enforcement** -- Tasks with a `timeout` field are now killed if they exceed the configured duration. Works with both per-task config and the global `task_timeout`/`--timeout` flag. [#​8250](https://redirect.github.com/jdx/mise/pull/8250) by [@​tvararu](https://redirect.github.com/tvararu) ```toml [tasks.deploy] run = "npm run deploy" timeout = "5m" ``` - **VSIX archive support** -- The HTTP backend now recognizes `.vsix` files as ZIP archives and extracts them correctly, enabling tools distributed as VS Code extensions to be installed via `http:` URLs. [#​8306](https://redirect.github.com/jdx/mise/pull/8306) by [@​sosumappu](https://redirect.github.com/sosumappu) - **Registry: `oxfmt`** -- Added the oxfmt formatter to the tool registry. [#​8316](https://redirect.github.com/jdx/mise/pull/8316) by [@​taoufik07](https://redirect.github.com/taoufik07) #### Changed - **Conda backend rewritten with rattler crates** -- Replaces custom version matching, dependency resolution, archive extraction, and binary patching with the battle-tested rattler ecosystem (`rattler_solve`, `rattler_repodata_gateway`, `rattler::install`). Binary prefix replacement now works correctly (the old code skipped binary files entirely). Since the conda backend is still experimental, this is a non-breaking change. [#​8325](https://redirect.github.com/jdx/mise/pull/8325) by [@​jdx](https://redirect.github.com/jdx) #### Fixed - **Lockfile not modified with `--locked`** -- `mise install --locked` no longer writes to `mise.lock`, matching the semantics of `cargo install --locked` and `uv pip install --locked`. [#​8308](https://redirect.github.com/jdx/mise/pull/8308) by [@​jdx](https://redirect.github.com/jdx) - **Orphan lockfile entries pruned** -- `mise lock` now removes stale tool entries that are no longer present in config, keeping the lockfile aligned with the current toolset. [#​8265](https://redirect.github.com/jdx/mise/pull/8265) by [@​mackwic](https://redirect.github.com/mackwic) - **Contradictory lockfile config caught early** -- Setting `locked=true` alongside `lockfile=false` now produces a clear error instead of silently ignoring the lock. [#​8329](https://redirect.github.com/jdx/mise/pull/8329) by [@​jdx](https://redirect.github.com/jdx) - **`watch_files` triggers on every change** -- The hook-env fast-path now checks `[[watch_files]]` paths, fixing a bug where only the first file change triggered the associated run command. [#​8317](https://redirect.github.com/jdx/mise/pull/8317) by [@​jdx](https://redirect.github.com/jdx) - **Fish alias completions cleaned up** -- Setting or unsetting shell aliases in fish now clears stale completions, preventing tab-complete from offering outdated suggestions. [#​8324](https://redirect.github.com/jdx/mise/pull/8324) by [@​jdx](https://redirect.github.com/jdx) - **JSON schema accepts age-encrypted env values** -- Fixed a `oneOf` ambiguity in the mise schema that rejected `[env]` entries using age encryption. [#​8328](https://redirect.github.com/jdx/mise/pull/8328) by [@​adamliang0](https://redirect.github.com/adamliang0) - **Regal registry updated** -- The regal tool now points to its new home at `open-policy-agent/regal`. [#​8315](https://redirect.github.com/jdx/mise/pull/8315) by [@​charlieegan3](https://redirect.github.com/charlieegan3) - **Conda: locked installs preserve package data** -- `conda_packages` entries are no longer silently dropped during `--locked` installs, and concurrent downloads no longer race on the same temp file. [#​8335](https://redirect.github.com/jdx/mise/pull/8335) by [@​jdx](https://redirect.github.com/jdx) - **Conda: solver no longer fails on Linux** -- Deduplicated repodata records before passing them to the solver, fixing "duplicate records" errors when installing tools like imagemagick. [#​8337](https://redirect.github.com/jdx/mise/pull/8337) by [@​jdx](https://redirect.github.com/jdx) #### New Contributors - [@​tvararu](https://redirect.github.com/tvararu) made their first contribution in [#​8250](https://redirect.github.com/jdx/mise/pull/8250) - [@​sosumappu](https://redirect.github.com/sosumappu) made their first contribution in [#​8306](https://redirect.github.com/jdx/mise/pull/8306) - [@​charlieegan3](https://redirect.github.com/charlieegan3) made their first contribution in [#​8315](https://redirect.github.com/jdx/mise/pull/8315) - [@​taoufik07](https://redirect.github.com/taoufik07) made their first contribution in [#​8316](https://redirect.github.com/jdx/mise/pull/8316) - [@​adamliang0](https://redirect.github.com/adamliang0) made their first contribution in [#​8328](https://redirect.github.com/jdx/mise/pull/8328) - [@​mackwic](https://redirect.github.com/mackwic) made their first contribution in [#​8265](https://redirect.github.com/jdx/mise/pull/8265) **Full Changelog**: ### [`v2026.2.19`](https://redirect.github.com/jdx/mise/releases/tag/v2026.2.19): : Fixes for interactive tasks and failed install cleanup [Compare Source](https://redirect.github.com/jdx/mise/compare/v2026.2.18...v2026.2.19) A small patch release with two targeted bug fixes: a regression fix for interactive task execution and better cleanup after failed installs. ##### Bug Fixes - **Interactive tasks no longer hang** -- The process group isolation added in v2026.2.18 ([#​8279](https://redirect.github.com/jdx/mise/pull/8279)) inadvertently broke interactive tools like Tilt that read from stdin. When a child process was moved to its own process group, the terminal wouldn't deliver keyboard input to it, causing `SIGTTIN` and a silent hang. mise now checks whether stdin is a TTY before calling `setpgid` -- interactive tasks stay in the terminal's foreground process group for proper keyboard I/O, while non-interactive tasks still get their own process group for clean signal teardown. [#​8301](https://redirect.github.com/jdx/mise/pull/8301) by [@​jdx](https://redirect.github.com/jdx) - **Failed installs clean up properly** -- When an install fails (e.g. a 404 for a non-existent version or a 403 from GitHub rate limiting), mise now removes the empty parent directory (e.g. `installs/tilt/`) and the stale incomplete marker from cache, instead of leaving them behind. [#​8302](https://redirect.github.com/jdx/mise/pull/8302) by [@​jdx](https://redirect.github.com/jdx) ##### Documentation - Fixed the ripgrep command in the getting-started guide to use the correct binary name `rg` instead of `ripgrep`. [#​8299](https://redirect.github.com/jdx/mise/pull/8299) by [@​nguyenvulong](https://redirect.github.com/nguyenvulong) **Full Changelog**: ### [`v2026.2.18`](https://redirect.github.com/jdx/mise/releases/tag/v2026.2.18): : Task Reliability & Developer Experience [Compare Source](https://redirect.github.com/jdx/mise/compare/v2026.2.17...v2026.2.18) A bug-fix-heavy release focused on task execution reliability, with a new feature for cross-platform tool locking. ##### Highlights - **Auto-lock all platforms after install** — When you install a tool, mise now automatically locks versions for all platforms (not just the current one). This means your `mise.lock` stays complete for teammates on different OSes without needing to run `mise lock` separately. [#​8277](https://redirect.github.com/jdx/mise/pull/8277) - **Process group cleanup for tasks** — Task child processes are now managed via Unix process groups, so killing a task reliably takes down the entire process tree instead of leaving orphaned children. [#​8279](https://redirect.github.com/jdx/mise/pull/8279) - **`depends_post` tasks run even on failure** — Post-dependency tasks (cleanup, notifications, etc.) now execute even when the parent task fails, matching the expected behavior for teardown-style hooks. [#​8274](https://redirect.github.com/jdx/mise/pull/8274) ##### Bug Fixes - **Infinite shim recursion on Unix** — `mise exec` now strips its own shims from `PATH` before spawning subprocesses, preventing infinite recursion when a shimmed tool calls itself. [#​8276](https://redirect.github.com/jdx/mise/pull/8276) - **`--yes` flag now works for config trust prompts** — The `--yes`/`-y` flag is now properly respected when mise prompts to trust a config file. [#​8288](https://redirect.github.com/jdx/mise/pull/8288) - **`--locked --dry-run` validation order** — `mise install --locked` now validates the lock requirement before the `--dry-run` short-circuit, so you get a proper error instead of silent success. [#​8290](https://redirect.github.com/jdx/mise/pull/8290) by [@​altendky](https://redirect.github.com/altendky) - **JSON Schema compatibility** — Replaced `unevaluatedProperties` with `additionalProperties` in the mise JSON schema for broader validator support. [#​8285](https://redirect.github.com/jdx/mise/pull/8285) - **Duplicate stderr on task failure** — Fixed tasks in replacing output mode printing error output twice on failure. [#​8275](https://redirect.github.com/jdx/mise/pull/8275) - **Did-you-mean for task commands** — Mistyping a CLI subcommand now suggests similar task names. [#​8286](https://redirect.github.com/jdx/mise/pull/8286) - **Monorepo prepare steps** — Prepare steps for subdirectory configs now execute from the repository root as expected. [#​8291](https://redirect.github.com/jdx/mise/pull/8291) - **`mise upgrade` no longer force-reinstalls** — Previously installed versions are skipped during upgrade instead of being redundantly reinstalled. [#​8282](https://redirect.github.com/jdx/mise/pull/8282) - **Terminal restore after `mise watch`** — `watchexec` no longer leaves the terminal in a broken state on exit. [#​8273](https://redirect.github.com/jdx/mise/pull/8273) ##### Documentation - Clarified that `MISE_CEILING_PATHS` excludes the ceiling directory itself. [#​8283](https://redirect.github.com/jdx/mise/pull/8283) ##### New Contributors - [@​altendky](https://redirect.github.com/altendky) made their first contribution in [#​8290](https://redirect.github.com/jdx/mise/pull/8290) ##### 📦 Aqua Registry Updates ##### New Packages (4) - [`Skarlso/crd-to-sample-yaml`](https://redirect.github.com/Skarlso/crd-to-sample-yaml) - [`kunobi-ninja/kunobi-releases`](https://redirect.github.com/kunobi-ninja/kunobi-releases) - [`swanysimon/markdownlint-rs`](https://redirect.github.com/swanysimon/markdownlint-rs) - [`tmux/tmux-builds`](https://redirect.github.com/tmux/tmux-builds) ##### Updated Packages (2) - [`firecow/gitlab-ci-local`](https://redirect.github.com/firecow/gitlab-ci-local) - [`k1LoW/runn`](https://redirect.github.com/k1LoW/runn) ### [`v2026.2.17`](https://redirect.github.com/jdx/mise/releases/tag/v2026.2.17): : Freshly Prepared [Compare Source](https://redirect.github.com/jdx/mise/compare/v2026.2.16...v2026.2.17) A moderate release with a handful of bug fixes and a new feature for the `prepare` system. ##### Highlights - **Prepare: auto-touch stale outputs** — When tools like `uv sync` skip work because dependencies are already satisfied, output files don't get updated, causing mise to consider them stale on the next run. Prepare providers now automatically touch output files after a successful command, keeping staleness checks accurate. This is controlled by a new `touch_outputs` config option (defaults to true). [#​8243](https://redirect.github.com/jdx/mise/pull/8243) by [@​halms](https://redirect.github.com/halms) - **Settings reorganization: `task_*` → `task.*`** — Nine flat `task_*` settings have been consolidated into a nested `task.*` namespace (e.g., `task_output` → `task.output`). The old names still work with no breaking changes — deprecation warnings won't appear until `2026.8.0`. [#​8239](https://redirect.github.com/jdx/mise/pull/8239) ##### Bug Fixes - **Postinstall hooks now use correct bin paths** — Per-tool postinstall hooks were hardcoding `$install_path/bin` on `PATH`, which broke backends like aqua where binaries live in non-standard subdirectories. Hooks now use each backend's actual binary paths. [#​8234](https://redirect.github.com/jdx/mise/pull/8234) - **`mise use` writes to the correct config file** — When both `config.toml` and `config.local.toml` exist, `mise use` was incorrectly writing to `config.local.toml`. It now properly targets `config.toml`. [#​8240](https://redirect.github.com/jdx/mise/pull/8240) - **Legacy `.mise.backend` installs no longer block auto-migration** — Legacy backend files were defaulting to `explicit_backend = true`, which prevented auto-migration to updated registry backends. They now default to non-explicit, allowing tools like `glab` to resolve correctly through the current registry. [#​8245](https://redirect.github.com/jdx/mise/pull/8245) by [@​jean-humann](https://redirect.github.com/jean-humann) ##### 📦 Aqua Registry Updates ##### Updated Packages (1) - [`namespacelabs/foundation/nsc`](https://redirect.github.com/namespacelabs/foundation/nsc) ### [`v2026.2.16`](https://redirect.github.com/jdx/mise/releases/tag/v2026.2.16): : MCP Gets Its Hands Dirty [Compare Source](https://redirect.github.com/jdx/mise/compare/v2026.2.15...v2026.2.16) This release brings MCP task execution support, better Node.js flavor guidance, and a solid round of bug fixes across several backends. ##### Highlights - **MCP `run_task` tool** — You can now execute mise tasks directly through the [MCP](https://mise.jdx.dev/) interface. The new `run_task` tool runs tasks via subprocess with full stdout/stderr capture, timeout support, and hardened execution. An `install_tool` stub is also included for future expansion. [#​8179](https://redirect.github.com/jdx/mise/pull/8179) by [@​joaommartins](https://redirect.github.com/joaommartins) - **Node flavor suggestions** — When a Node.js version isn't found in the configured mirror, mise now suggests setting `node.flavor` to help you get to the right download faster. [#​8206](https://redirect.github.com/jdx/mise/pull/8206) by [@​risu729](https://redirect.github.com/risu729) - **Registry stack overflow fix** — The registry `BTreeMap` is now built directly on the heap, eliminating a stack overflow that could occur with large registries. [#​8214](https://redirect.github.com/jdx/mise/pull/8214) by [@​risu729](https://redirect.github.com/risu729) ##### Bug Fixes - **Java version sorting** — Shorthand Java versions (e.g., `21`, `17`) now sort correctly. [#​8197](https://redirect.github.com/jdx/mise/pull/8197) by [@​roele](https://redirect.github.com/roele) - **Node env var migration** — Node-related environment variables have been properly migrated to the settings system. [#​8200](https://redirect.github.com/jdx/mise/pull/8200) by [@​risu729](https://redirect.github.com/risu729) - **Registry overrides in shims** — Registry overrides are now correctly applied when running tools through shims. [#​8199](https://redirect.github.com/jdx/mise/pull/8199) by [@​risu729](https://redirect.github.com/risu729) - **Rust outdated duplication** — Fixed `mise outdated` showing Rust versions twice. [#​8209](https://redirect.github.com/jdx/mise/pull/8209) by [@​roele](https://redirect.github.com/roele) - **GitHub aliased backend resolution** — Version lookups no longer break for tools aliased to a different backend than the registry default. [#​8221](https://redirect.github.com/jdx/mise/pull/8221) - **GitHub attestation output** — Attestation verification success is now shown in progress output. [#​8230](https://redirect.github.com/jdx/mise/pull/8230) - **Cargo binstall setting migration** — `MISE_CARGO_BINSTALL_ONLY` has been migrated to the settings system. [#​8202](https://redirect.github.com/jdx/mise/pull/8202) by [@​risu729](https://redirect.github.com/risu729) ##### New Tools - **typst** — GitHub backend added. [#​8210](https://redirect.github.com/jdx/mise/pull/8210) by [@​3w36zj6](https://redirect.github.com/3w36zj6) - **cargo-dist** — Now available via aqua registry. [#​8153](https://redirect.github.com/jdx/mise/pull/8153) by [@​risu729](https://redirect.github.com/risu729) - **release-plz** — Now available via aqua registry. [#​8150](https://redirect.github.com/jdx/mise/pull/8150) by [@​risu729](https://redirect.github.com/risu729) ### [`v2026.2.15`](https://redirect.github.com/jdx/mise/releases/tag/v2026.2.15): : Streaming in Order [Compare Source](https://redirect.github.com/jdx/mise/compare/v2026.2.14...v2026.2.15) This release brings a nice quality-of-life improvement to task execution along with a solid batch of bug fixes across several subsystems. ##### Highlights - **Real-time streaming for keep-order tasks** — The `keep_order` task output mode now streams the active task's output in real-time instead of buffering everything until completion. Other parallel tasks buffer quietly and flush in definition order as they finish, so you get live feedback without sacrificing deterministic output ordering. [#​8164](https://redirect.github.com/jdx/mise/pull/8164) - **npm backend performance** — `npm view` is now called only once per package lookup instead of multiple times, speeding up npm-based tool resolution. Thanks [@​risu729](https://redirect.github.com/risu729)! [#​8181](https://redirect.github.com/jdx/mise/pull/8181) ##### Bug Fixes - **Recursive shim execution on Windows** — `mise exec` now strips the shims directory from PATH during executable lookup, preventing infinite recursion when shims call back into `mise x`. [#​8189](https://redirect.github.com/jdx/mise/pull/8189) - **PATH reordering after activation** — `hook-env` now preserves any PATH reordering done after `mise activate` (e.g., by `~/.zlogin`), instead of silently reverting to the original order. [#​8190](https://redirect.github.com/jdx/mise/pull/8190) - **Cross-platform lockfile resolution** — The aqua backend now correctly resolves lockfile artifacts for the target platform instead of leaking host-specific overrides into `mise lock --platform`. Thanks [@​mackwic](https://redirect.github.com/mackwic)! [#​8183](https://redirect.github.com/jdx/mise/pull/8183) - **Version alias lockfile lookup** — Version aliases (like `lts`) are now resolved before lockfile lookup, so locked versions are matched correctly. [#​8194](https://redirect.github.com/jdx/mise/pull/8194) - **Task source freshness checks** — Freshness checks now work correctly with dynamic task directories. Thanks [@​rooperuu](https://redirect.github.com/rooperuu)! [#​8169](https://redirect.github.com/jdx/mise/pull/8169) - **Global tasks in monorepos** — Global tasks are now properly resolved when running from a monorepo root. [#​8192](https://redirect.github.com/jdx/mise/pull/8192) - **Wildcard glob matching** — `test:*` no longer incorrectly matches the parent `test` task. [#​8165](https://redirect.github.com/jdx/mise/pull/8165) - **task\_config.includes paths** — Include paths in task config are now resolved relative to the config root, not the working directory. [#​8193](https://redirect.github.com/jdx/mise/pull/8193) - **Upgrade safety** — `mise upgrade` now skips untrusted tracked configs instead of failing. [#​8195](https://redirect.github.com/jdx/mise/pull/8195) - **helm-diff registry entry** — Fixed the archive binary name for helm-diff. Thanks [@​jean-humann](https://redirect.github.com/jean-humann)! [#​8173](https://redirect.github.com/jdx/mise/pull/8173) ##### New Contributors Welcome [@​jean-humann](https://redirect.github.com/jean-humann), [@​mackwic](https://redirect.github.com/mackwic), and [@​rooperuu](https://redirect.github.com/rooperuu)! ##### 📦 Aqua Registry Updates ##### New Packages (2) - [`BetterDiscord/cli`](https://redirect.github.com/BetterDiscord/cli) - [`glossia.ai/cli`](https://redirect.github.com/glossia.ai/cli) ### [`v2026.2.14`](https://redirect.github.com/jdx/mise/releases/tag/v2026.2.14) [Compare Source](https://redirect.github.com/jdx/mise/compare/v2026.2.13...v2026.2.14) A feature-focused release adding vfox plugin env redaction, Deno devEngines support, and a new Rust default\_host setting. ##### Highlights - **Vfox env var redaction** — Vfox plugins can now request that specific environment variables be redacted from logs and debug output by returning a `redact` field in `MiseEnvResult`. Useful for plugins that inject secrets or tokens. [#​8166](https://redirect.github.com/jdx/mise/pull/8166) - **Deno devEngines.runtime support** — Mise now reads the `devEngines.runtime` field from `package.json` to auto-detect the desired Deno version, matching the same convention already supported for Node. Thanks [@​risu729](https://redirect.github.com/risu729)! [#​8144](https://redirect.github.com/jdx/mise/pull/8144) - **`default_host` setting for Rust** — A new `rust.default_host` setting lets you override the Rust target triple used during installation, useful for cross-compilation setups. Thanks [@​aacebedo](https://redirect.github.com/aacebedo)! [#​8154](https://redirect.github.com/jdx/mise/pull/8154) - **Aqua `github_content` package support** — The aqua backend now supports packages hosted via GitHub content downloads (not just releases). Thanks [@​risu729](https://redirect.github.com/risu729)! [#​8147](https://redirect.github.com/jdx/mise/pull/8147) ##### Bug Fixes - **`mise edit` whitespace** — TOML values edited via `mise edit` no longer retain extra formatting whitespace. [#​8162](https://redirect.github.com/jdx/mise/pull/8162) - **`--locked` for python/ubi** — The `--locked` flag now works correctly with python and ubi backends. [#​8163](https://redirect.github.com/jdx/mise/pull/8163) - **npm update notifier** — The npm update notifier is now suppressed during `npm install`, preventing spurious output. Thanks [@​risu729](https://redirect.github.com/risu729)! [#​8152](https://redirect.github.com/jdx/mise/pull/8152) - **Asset matcher vsix penalty** — `.vsix` files are now deprioritized in asset matching, preventing incorrect downloads. Thanks [@​risu729](https://redirect.github.com/risu729)! [#​8151](https://redirect.github.com/jdx/mise/pull/8151) - **JSON schema updates** — Added missing `task_templates`, `extends`, and `timeout` fields to the mise.json schema. Thanks [@​risu729](https://redirect.github.com/risu729)! [#​8145](https://redirect.github.com/jdx/mise/pull/8145) ##### New Contributors Welcome [@​joaommartins](https://redirect.github.com/joaommartins)! [#​8133](https://redirect.github.com/jdx/mise/pull/8133) *** > **Note:** This release has no attached binary assets. The v2026.2.14 tag was created successfully but the GitHub Actions workflow that publishes release artifacts did not trigger for the tag push. The binaries for this version are functionally identical to v2026.2.15 minus the additional fixes in that release. Use v2026.2.15 instead. ### [`v2026.2.13`](https://redirect.github.com/jdx/mise/releases/tag/v2026.2.13): : Fix GitHub attestation verification failures [Compare Source](https://redirect.github.com/jdx/mise/compare/v2026.2.12...v2026.2.13) This release partially mitigates GitHub attestation verification failures that were causing tool installations to fail (e.g., `gh`, and other aqua-backed tools with attestations enabled). See [#​8142](https://redirect.github.com/jdx/mise/discussions/8142) for details. ##### What happened GitHub silently changed their attestations API to externalize bundle storage to Azure Blob Storage (`tmaproduction.blob.core.windows.net`) using [Snappy compression](https://google.github.io/snappy/), rather than returning bundles inline as JSON. The `gh` CLI had already been updated to handle this ([cli/cli#10185](https://redirect.github.com/cli/cli/pull/10185)), but third-party tools like mise were not yet aware of the new format, causing `"error decoding response body"` failures. ##### What this release does Bumps `sigstore-verification` to 0.2, which splits the reqwest dependency version from mise's (0.13 vs 0.12). This avoids Cargo feature unification that was causing mise's `gzip` feature to be applied to attestation requests, interfering with the Snappy-compressed responses. **Note:** A full fix with proper Snappy decompression support and auth token scoping landed in [sigstore-verification v0.2.1](https://redirect.github.com/jdx/sigstore-verification/releases/tag/v0.2.1) ([#​22](https://redirect.github.com/jdx/sigstore-verification/pull/22), [#​23](https://redirect.github.com/jdx/sigstore-verification/pull/23)) — expect a follow-up mise release with that bump. If you are still hitting issues, set `settings.aqua.github_attestations = false` as a workaround. ##### Dependency Updates - **Bumped `sigstore-verification` to 0.2** ([e8897c9](https://redirect.github.com/jdx/mise/commit/e8897c9fbc873fe272495a65e5a88b04b97f3b6d)) ##### 📦 Aqua Registry Updates ##### New Packages (1) - [`k1LoW/tcmux`](https://redirect.github.com/k1LoW/tcmux) ##### Updated Packages (1) - [`jdx/usage`](https://redirect.github.com/jdx/usage) ### [`v2026.2.12`](https://redirect.github.com/jdx/mise/releases/tag/v2026.2.12) [Compare Source](https://redirect.github.com/jdx/mise/compare/aqua-registry-v2026.2.11...v2026.2.12) A small release adding a new Java configuration option. ##### Highlights - **`java.shorthand_vendor` setting** — A new setting that lets you configure which vendor is used when specifying shorthand Java versions (e.g., `21` instead of `temurin-21`). Thanks [@​roele](https://redirect.github.com/roele)! [#​8134](https://redirect.github.com/jdx/mise/pull/8134) *** > **Note:** This release has no attached binary assets. The v2026.2.12 tag was created but the GitHub Actions workflow that publishes release artifacts did not trigger for the tag push. Use v2026.2.13 or later instead.

+## Signing Off Commits
+
+Every commit must include a `Signed-off-by` line, as required by the
+[Developer Certificate of Origin (DCO)](https://developercertificate.org/).
+
+Sign off each commit by passing `--signoff` (or `-s`) to `git commit`:
+
+```bash
+git commit --signoff -m "Your commit message"
+```
+
+To sign off only the most recent commit, use `--amend`:
+
+```bash
+git commit --amend --signoff --no-edit
+```
+
+To sign off multiple commits, rebase (replace `N` with the number of commits):
+
+```bash
+git rebase --signoff HEAD~N
+```
+
+Then force-push the branch:
+
+```bash
+git push --force-with-lease
+```
+

Subject: [PATCH 869/870] fix: reduce lychee retries to avoid compounding
 GitHub 429s (#1940)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

- Reduce `max_retries` from 6 to 2 and increase `retry_wait_time` from
5s to 10s
- 6 retries with 5s wait compounds 429 rate limiting from GitHub — many
rapid retries keep triggering rate limits
- Fewer retries with longer wait between them is more effective at
recovering from 429s

## Test plan

- [ ] Link check CI workflow passes without hitting sustained 429 errors

Subject: [PATCH 870/870] fix: use /tree/ instead of /blob/ for directory URL
 (#1944)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary
- Fix tail sampling processor link in `docs/content/otel/tracing.md` to
use `/tree/` instead of `/blob/`
- The link points to a directory, not a file. GitHub redirects `/blob/`
→ `/tree/` (301), but link checkers that remap to
`raw.githubusercontent.com` get 400 for directories

## Test plan
- [ ] Link checker passes
