Hi, I'm Shii-chan! Today I have a quiet but important update for anyone running Java in production.

AWS What's New aws.amazon.com

What was announced?

AWS shared in its What's New feed that Amazon Corretto has received its quarterly security and critical-fix update. Amazon Corretto is AWS's no-cost, production-ready distribution of OpenJDK.

Here are the builds released this time:

  • Corretto 26.0.2
  • Corretto 25.0.4
  • Corretto 21.0.12 (LTS)
  • Corretto 17.0.20 (LTS)
  • Corretto 11.0.32 (LTS)
  • Corretto 8u502 (LTS)

Both Long-Term Support (LTS) and Feature Release (FR) versions were updated together.

What changes

Beyond the version bump, this release also changes some of the distribution's underlying details.

  • New default base for Docker images: Starting with this release, the default Amazon Corretto Docker images are based on Amazon Linux 2023. The previous default, Amazon Linux 2 based images, will continue to be offered as a non-default option for customers who can't migrate yet
  • JavaFX no longer bundled with Corretto 8: Starting with this release, JavaFX binaries are no longer included with Corretto 8. Migration guidance is available in the Corretto 8 GitHub repository, so if you rely on JavaFX with Corretto 8, it's worth checking that out

Dive Deep

Getting the updates works the same way as before: you can download them from the Corretto home page, or, on Linux, configure an Apt, Yum, or Apk repository to pull updates through your package manager.

Wrap-up

  • Corretto 26.0.2, 25.0.4, 21.0.12, 17.0.20, 11.0.32, and 8u502 are now available
  • Default Docker images switch from Amazon Linux 2 to Amazon Linux 2023 (Amazon Linux 2 based images remain available as a non-default option)
  • JavaFX binaries are no longer bundled with Corretto 8 (see the Corretto 8 GitHub for migration guidance)
  • Updates are available via the download page as well as Apt, Yum, and Apk repositories

If you're running OpenJDK in production or maintaining Corretto based Docker images, it's a good idea to pull this update in during your next maintenance window!
