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/).

 > - 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.
 
 **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.
