The Play Team is happy to announce the release of Play 2.9.9! 🎉

:green_book: About this Release

This patch release upgrades dependencies, fixes minor bugs, comes with support for Java 25 and improves compatibility with Scala 3. We recommend upgrading as soon as possible.

If you're considering upgrading to Play 2.9, please check the Play 2.9 release announcement for highlights and further details on how to migrate. Many projects have already smoothly upgraded to Play 2.9.

Official support for Java 25

Starting with this release, Play officially supports Java 25. Since all tests passed when running on the latest Java 25 release candidate, we are comfortable declaring Java 25 officially supported by Play.
