 ## What's new

-### V6 (in development)
+### V6

 - Migrated the action implementation to ESM to support the latest `@actions/*` packages.
- Added the `oracle-openjdk` distribution for OpenJDK builds from Oracle.
+- 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 `java-version: latest` to resolve the newest stable GA release from the distribution's remote metadata.
- JDK downloads now automatically verify authoritative checksums for [supported distributions](#download-integrity-and-signatures).
+- 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. Package signature verification is supported for Temurin and Microsoft builds, with configurable strict enforcement.
 - 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.
@@ -73,6 +69,7 @@ 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`.
+- See the [complete V6 release notes](https://github.com/actions/setup-java/releases/tag/v6.0.0) for all enhancements and fixes.

 Distributions or individual releases without an authoritative checksum continue to install normally, with the omission reported in debug logs. Installations resolved directly from the runner tool cache — including JDKs preinstalled on the runner image and JDKs installed by an earlier step of the same job — are not downloaded again and are not reverified, even when `verify-signature: true` is set. Use `force-download: true` to always download and verify the archive.

-Use `verify-signature: true` to verify package signatures for distributions that support it. Currently supported distributions are `temurin` and `microsoft`; setting it for an unsupported distribution fails the workflow.
+Package signature verification is supported for `temurin` and `microsoft`. When `verify-signature` is omitted, the action checks the signature and warns if GPG is unavailable or verification fails, but does not enforce the result. Explicitly setting `verify-signature: true` enforces verification and makes these failures fatal. Setting `verify-signature: true` for an unsupported distribution also fails the workflow.
+
+> [!WARNING]
+> Requesting explicit signature verification with verify-signature can fail a build after an unexpected but legitimate vendor signing-key rotation, because the action's bundled keys may not yet include the new key. Confirm a new key through the vendor's trusted documentation before using it.
+
+After confirming a legitimate rotation, configure the updated key with `verify-signature-public-key`. The input accepts one or more ASCII-armored public keys; concatenate complete armored key blocks when both old and new vendor keys are needed during a transition. Custom keys replace, rather than extend, the keys bundled with the selected distribution.

+    verify-signature-public-key: |
+      -----BEGIN PGP PUBLIC KEY BLOCK-----
+      ...vendor key material...
+      -----END PGP PUBLIC KEY BLOCK-----
+```
+
+As a temporary fallback while a legitimate rotation is being investigated, set `verify-signature: false`. This disables package signature verification, although authoritative checksum verification still applies when the vendor publishes a checksum.

+ * optional whitespace group followed by a required "non-whitespace" group.
+ * On a long run of whitespace that never resolves into an attribute name
+ * (e.g. a tag with thousands of trailing spaces before `>`), the engine

+ * this way no matter how much whitespace the input contains — it's always
+ * proportional to the length of the string, once.
+ *
+ * Each returned token mirrors the shape the old regex match array had, so

+ *   token[6]          - the value's text, without the surrounding quotes
+ *

+ * optional whitespace group followed by a required "non-whitespace" group.
+ * On a long run of whitespace that never resolves into an attribute name

+ * this way no matter how much whitespace the input contains — it's always
+ * proportional to the length of the string, once.
+ *
+ * Each returned token mirrors the shape the old regex match array had, so
+ * the validation logic below (which reads token[1]..token[6]) didn't need

+ *   token[6]          - the value's text, without the surrounding quotes
+ *
+ * A malformed leading character (e.g. a stray '=' with no name before it)

 ## 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.

+Maven Central is included first by default. Set
+`mvn-repositories-prioritize-central: false` to place custom repositories
+first, or set `mvn-repositories-include-central: false` to disable Central. The
+generated profile overrides the Central repository inherited from Maven's Super
+POM with releases and snapshots disabled. When automatic Central inclusion is
+off, the ID `central` may instead be declared explicitly in `mvn-repositories`
+to replace it with a user-specified repository; otherwise that ID is reserved
+to prevent duplicate entries.

 ### GPG

 The example above uses the [Maven GPG Plugin](https://maven.apache.org/plugins/maven-gpg-plugin/)'s Bouncy Castle signer (`-Dgpg.signer=bc`, available since `maven-gpg-plugin` 3.2.0). It is a pure-Java signer that reads the key directly from the `MAVEN_GPG_KEY` environment variable, so it does **not** require the `gpg` executable, importing the key into a GPG keychain, or the `--pinentry-mode loopback` workaround in your `pom.xml`. The key must be an ASCII-armored secret key (transferable secret key format).
