 > [!NOTE]
 > - The different distributors can provide discrepant list of available versions / supported configurations. Please refer to the official documentation to see the list of supported versions.
 > - AdoptOpenJDK got moved to Eclipse Temurin and won't be updated anymore. It is highly recommended to migrate workflows from `adopt` and `adopt-openj9`, to `temurin` and `semeru` respectively, 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/).
+> - Oracle OpenJDK builds are created and hosted by Oracle. After a limited number of releases, Oracle archives these builds and no longer provides security updates. To continue receiving security patches, users must move to Oracle JDK or choose a different vendor.
 > - For Azul Zulu OpenJDK, architecture `arm64` is mapped to `aarch64` when querying the Azul Metadata API.
 > - 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.
 > - GraalVM Community is available as `distribution: 'graalvm-community'` for stable JDK 17 and later releases published on GitHub.
