-## 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.

+**NOTE:** The legacy AdoptOpenJDK distributions are deprecated and will be removed in setup-java v6. Migrate `adopt` and `adopt-hotspot` to `temurin`, and `adopt-openj9` to `semeru`, to keep receiving software and security updates. See more details in the [Good-bye AdoptOpenJDK post](https://blog.adoptopenjdk.net/2021/08/goodbye-adoptopenjdk-hello-adoptium/).
 
 **NOTE:** For Azul Zulu OpenJDK architectures x64 and arm64 are mapped to x86 / arm with proper hw_bitness.
 
 **NOTE:** To comply with the GraalVM Free Terms and Conditions (GFTC) license, it is recommended to use GraalVM JDK 17 version 17.0.12, as this is the only version of GraalVM JDK 17 available under the GFTC license. Additionally, it is encouraged to consider upgrading to GraalVM JDK 21, which offers the latest features and improvements.
 
-**NOTE:** Oracle JDK 17 licensing varies by patch level. As shown on the [JDK 17 Archive](https://www.oracle.com/java/technologies/javase/jdk17-archive-downloads.html) (versions up to 17.0.12 are under the [NFTC](https://www.oracle.com/downloads/licenses/no-fee-license.html) license) and the [JDK 17.0.13+ Archive](https://www.oracle.com/java/technologies/javase/jdk17-0-13-later-archive-downloads.html) (versions 17.0.13 and later are under the [OTN](https://www.oracle.com/downloads/licenses/javase-license1.html) license). To stay on the free NFTC license, use `distribution: 'oracle'` with `java-version: '17.0.12'` (or earlier) instead of the floating `'17'`. Alternatively, upgrade to Oracle JDK 21+, which remains under the NFTC license.

-**NOTE:** On Ubuntu runners, commands executed via `sudo` do not inherit the `JAVA_HOME` and `PATH` set by `setup-java` and will fall back to the runner image's system-default JDK.

 ### Caching packages dependencies
 The action has a built-in functionality for caching and restoring dependencies. It uses [toolkit/cache](https://github.com/actions/toolkit/tree/main/packages/cache) under hood for caching dependencies but requires less configuration settings. Supported package managers are gradle, maven and sbt. The format of the used cache key is `setup-java-${{ platform }}-${{ packageManager }}-${{ fileHash }}`, where the hash is based on the following files:

-Using the `cache: gradle` provides a simple and effective way to cache Gradle dependencies with minimal configuration.

-For projects that require more advanced `Gradle` caching features, such as caching build outputs, support for Gradle configuration cache, encrypted cache storage, fine-grained cache control (including options to enable or disable the cache, set it to read-only or write-only, perform automated cleanup, and define custom cache rules), or optimized performance for complex CI workflows, consider using [`gradle/actions/setup-gradle`](https://github.com/gradle/actions/tree/main/setup-gradle).
