Hi devs, Updates on the progress of release.
In the past week, more than 20 issues were resolved for release 1.12.1. Thanks for the efforts. We still have 3 unresolved release blockers at the moment. - [FLINK-20648] Unable to restore from savepoints with Kubernetes HA. Consensus has been reached on the solution. @Yang Wang is working on a PR. - [FLINK-20654] Unaligned checkpoint recovery may lead to corrupted data stream. @Roman Khachatryan is still investigating the problem. - [FLINK-20664] Support setting service account for TaskManager pod. Boris Lublinsky has opened a PR, which is already reviewed and close to mergeable. Since we are targeting a swift release, I'm not intended to further delay the release for other non-blocker issues, unless there's a good reason. If there's anything that you believe is absolutely necessary for release 1.12.1, please reach out to me. Otherwise, the voting process will be started as soon as the above blockers are addressed.
