In his weekly Hashtag Jakarta EE blog, Ivar Grimstad, Jakarta EE Developer Advocate at the Eclipse Foundation, provided an update on Jakarta EE 11 and plans for Jakarta EE 12, writing:

The refactoring efforts of the Jakarta EE Platform TCK are moving along. There is not a final date yet, but it looks like sometime in the mid-to-end of November is realistic. There could potentially be a big release party at JakartaOne Livestream.

A draft of the plan for Jakarta EE 12 is in development, targeting a release in the first half of 2026. Notably, Jakarta EE 12 implementations must be certified on Java 21, Java 25, or both. This dual Java version targeting maintains consistency with practices established since Jakarta EE 9.

The JakartaOne Livestream 2024 conference is set for December 3, 2024.
