-## Breaking changes in V5
-
- Upgraded action from node20 to node24
-  > Make sure your runner is on version v2.327.1 or later to ensure compatibility with this release [Release Notes](https://github.com/actions/runner/releases/tag/v2.327.1)
-
-For more details,  see the full release notes on the [releases page](https://github.com/actions/setup-java/releases/tag/v5.0.0)
-
 ## V2 vs V1

 - V2 supports custom distributions and provides support for Azul Zulu OpenJDK, Eclipse Temurin and AdoptOpenJDK  out of the box. V1 supports only Azul Zulu OpenJDK.
 - V2 requires you to specify distribution along with the version. V1 defaults to Azul Zulu OpenJDK, only version input is required. Follow [the migration guide](docs/switching-to-v2.md) to switch from V1 to V2.

-For information about the latest releases, recent updates, and newly supported distributions, please refer to the `setup-java` [Releases](https://github.com/actions/setup-java/releases).

 ## Usage

  - `java-version`: The Java version that is going to be set up. Takes a whole or [semver](#supported-version-syntax) Java version. If not specified, the action will expect `java-version-file` input to be specified.

-All configured Java versions are added to the PATH. The last one added to the PATH (i.e., the last JDK set up by this action) will be used as the default and available globally. Other Java versions can be accessed through environment variables such as 'JAVA_HOME_{{ MAJOR_VERSION }}_{{ ARCHITECTURE }}'. To use a specific Java version, set the JAVA_HOME environment variable accordingly and prepend its bin directory to the PATH to ensure it takes priority during execution.

-  Supported files are `.java-version`, `.tool-versions` and `.sdkmanrc`.
-  * In `.java-version` file, only the version should be specified (e.g., 17.0.7). The `.java-version` file recognizes all variants of the version description according to [jenv](https://github.com/jenv/jenv).
-  * In `.tool-versions` file, java version should be preceded by the java keyword (e.g., java 17.0.7). The `.tool-versions` file supports version specifications in accordance with [asdf](https://github.com/asdf-vm/asdf) standards, adhering to Semantic Versioning ([semver](https://semver.org/)).
-  * In `.sdkmanrc` file, java version should be preceded by the `java=` prefix (e.g., java=17.0.7-tem) and include the distribution. The `.sdkmanrc` file supports version specifications in accordance with [file format](https://sdkman.io/usage#env-command), see [Sdkman! documentation](https://sdkman.io/jdks) for more information.
+  Supported files are .java-version and .tool-versions.

-For the tool-version file, ensure that you use standard semantic versioning (semver) formats, as non-standard formats (such as jetbrains-21b212.1) may not be parsed correctly. Additionally, for complex version strings containing multiple version-like segments (for example, java semeru-openj9-11.0.15+10_openj9-0.32.0), the extraction logic may incorrectly capture the last segment (0.32.0) instead of the main version (11.0.15+10).
