There are performance improvements across the board in the runtime, compilers, and libraries. Both of these low-pause garbage collectors get performance improvements in this release, and Corretto 17 is where we plan to introduce a preview of Generational Shenandoah in the near future. OpenJDK 17 continues to offer Shenandoah GC and is the first LTS release in which ZGC is generally available. OpenJDK 17 offers exciting new features compared to OpenJDK 11. We will move Corretto to this model and we will offer a new Corretto LTS every two years, starting with Corretto 17. Also, it will let developers and enterprises reap performance and reliability benefits sooner than before. It will help to keep OpenJDK vibrant and relevant, and encourage adoption of newer JDK versions. We believe that this new cadence will be positive for the community. The JDK 17 GA announcement also includes the intention to deliver one LTS JDK version every two years instead of the current three. We are pleased to announce that Amazon will continue to support Corretto 17 with security patches and critical updates until at least July 2029. The JDK community has declared that OpenJDK 17 will be a long-term supported (LTS) version, which means it will continue to be updated beyond the standard two quarterly updates until OpenJDK 18 is released in March 2022. Amazon Corretto is a no-cost, multi-platform, production-ready distribution of the Open Java Development Kit (OpenJDK). In September, we announced the general availability of Amazon Corretto 17.
