-## 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.

 ### 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).

 ## Java version file
   If the `java-version-file` input is specified, the action will extract the version from the file and install it.
   
-  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.
+  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). Similarly, 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/)).
+  
+  If both java-version and java-version-file inputs are provided, the java-version input will be used.
 
-    
-  If both `java-version` and `java-version-file` **inputs** are provided, the `java-version` input will be used.
-
-**Example step using `Sdkman!`**:
-```yml
-  - name: Setup java
-    uses: actions/setup-java@v5
-    with:
-      java-version-file: '.sdkmanrc'
-      distribution: 'temurin'
-```
-
-**Example `.sdkmanrc`**:
-```
-java=17.0.7-tem
-```
-
-Valid entry options (does not apply to `.sdkmanrc`):
+Valid entry options:
 ```
 major versions: 8, 11, 16, 17, 21
 more specific versions: 8.0.282+8, 8.0.232, 11.0, 11.0.4, 17.0
 early access (EA) versions: 15-ea, 15.0.0-ea
 versions with specified distribution: openjdk64-11.0.2
-LTS versions : temurin-21.0.5+11.0.LTS
 ```
 If the file contains multiple versions, only the first one will be recognized.
-
-***NOTE***:
-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).
