It's been about a month since 5.12.0 was released and there are already a good number of fixes contributed towards 5.12.1 so I'd like to start working on a 5.12.1 release in a few days.
If there is anything major that would be a blocker, let me know. Here are the current release notes: https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12311210&version=12333269
