 - Migrated the action implementation to ESM to support the latest `@actions/*` packages.
-- Added Oracle OpenJDK (`oracle-openjdk`), Red Hat Build of OpenJDK (`redhat`), and Liberica Native Image Kit (`liberica-nik`), and expanded Tencent Kona support through JDK 25.
+- Added the `oracle-openjdk` distribution for OpenJDK builds from Oracle.
 - Added `java-version: latest` to resolve the newest stable GA release from the distribution's remote metadata.
-- Expanded install compatibility with JEP 322 multi-field versions such as `18.0.1.1`, Temurin `jdk+jmods` packages, and native musl artifacts on Alpine for Dragonwell, Corretto, Zulu, and Liberica.
+- JDK downloads now automatically verify authoritative checksums for [supported distributions](#download-integrity-and-signatures).
-- JDK downloads now automatically verify authoritative checksums, and package signature verification defaults to enabled for Temurin and Microsoft builds.
 - Added `force-download: true` to bypass the tool cache and perform a reproducible fresh install.
 - Dependency caching now supports custom paths with `cache-path` and restore-only operation with `cache-read-only: true`.
-- Dependency cache keys now include `.mvn/extensions.xml` and `gradle.properties`, preventing stale restores when Maven extensions or Gradle dependency properties change.
 - Downloaded JDKs are now [cached](#caching-jdk-installations) automatically when `cache` is set; use `cache-jdk` to enable or disable it independently.
-- Warm JDK-cached jobs can reuse cached release metadata, avoiding vendor API calls while retaining a stale-metadata fallback for vendor outages and rate limits.
-- Maven configuration now supports multiple server credentials and custom dependency-resolution repositories.
-- Maven signing keys are imported into an isolated temporary GPG home instead of the runner's default keyring.
 - Set `problem-matcher: false` to disable Java compiler and uncaught-exception annotations.
 - GraalVM distributions now set `GRAALVM_HOME` in addition to `JAVA_HOME`.
 - Invalid boolean values, unsupported distribution/package/platform combinations, and mismatched Maven toolchain ID counts now fail with targeted errors.
@@ -69,7 +73,6 @@ steps:
 - Deprecated aliases still work, but emit warnings.
 - Maven GPG passphrases are now passed through `gpg.passphraseEnvName` instead of a deprecated `gpg.passphrase` server entry in `settings.xml`. This requires `maven-gpg-plugin` 3.2.0 or newer. See [GPG](docs/advanced-usage.md#gpg).
 - Legacy AdoptOpenJDK distributions were removed. Use `temurin` instead of `adopt` or `adopt-hotspot`, and `semeru` instead of `adopt-openj9`.

 ## Selecting a Java distribution
 `java-version` and `distribution` select what gets installed. `java-version` may be replaced by `java-version-file`, and `distribution` is optional only when `java-version-file` points to a `.sdkmanrc` or `.tool-versions` file that carries a recognized vendor identifier. In every other case both inputs must be provided. See [Supported distributions](../README.md#Supported-distributions) for a list of available options.
