Hi community,
I’d like to propose adding PR #12990 to the P0 /
release-blocking list for SeaTunnel 3.1.0.
This PR fixes ChainedMapTransform deserialization and preserves the
serialVersionUID used by streams written before #12804. Since this affects
restoring serialized state across upgrades, I believe it should be merged
before the 3.1.0 release. Anyone who has time to review the PR would be greatly
appreciated.
Best,
JeremyXin

主题：[apache/seatunnel] [Roadmap] Apache SeaTunnel 3.1.0 Roadmap (Issue #12949)
nzw921rx created an issue (apache/seatunnel#12949)
Hello everyone,
Thank you for your active participation in the discussion on stability fixes
after the Apache SeaTunnel 3.0.0 release.
This is a draft roadmap for 3.1.0 stability fixes, compiled from the fixes
submitted by the community since the 3.0.0 release and the currently open pull
requests.
It is only a discussion summary, not a final decision. You are welcome to
suggest changes, add missing items, or claim any item you are interested in.
Priorities for this round: data correctness and data loss; Zeta recovery,
checkpoint, and cancellation; hangs and leaks; type precision; well-scoped
changes.
Release-blocking = must be merged before 3.1.0; non-blocking = may ship
with 3.1.0 or in a later 3.1.x release.
