Yes. We should open a discussion / vote with different options for EOLing 2.x (since resources to maintain 2.x branches and getting the votes needed for a release are quite sparse).
Think primary questions for that would be: (a) Do we have consensus that such an EOL announcement is long overdue and should be put out rather soonish? (b) Time of the announcement: Options that I see: - b1: Directly with the projected release of the 3.0.0 marking it as the last release ever to be expected for OpenNLP 2.x - b2: Shortly after - with a grace period - for instance End of Year 2026, or similar short ranged targets. - b3: Mid of year 2027 Gruß Richard On 2026/07/07 22:44:52 Rui Abreu wrote: > Created this PR https://github.com/apache/storm/pull/8893 to set the > baseline as Java 25. > Additionally, we should vote on setting Apache Storm 2.x as EOL (it is > only receiving dependabot updates at this point) > > Thank you > > On Mon, 29 Jun 2026 at 14:34, Richard Zowalla <[email protected]> wrote: > > > > +1 on thinking about Java 25 for 3.0.0 rather than just bumping to 21. > > > > The reason it is worth it now is the pinning fix: JEP 491 ("Synchronize > > Virtual Threads without Pinning"), delivered in Java 24 and carried into > > the 25 LTS.
