JDK 27, the reference implementation of Java 27, is now Generally Available. We shipped build 35 as the second Release Candidate of JDK 27 on 20 August, and no P1 bugs have been reported since then. Build 35 is therefore now the GA build, ready for production use. GPL-licensed OpenJDK builds from Oracle are available here: https://jdk.java.net/27 Builds from other vendors will no doubt be available soon.
