Hello,
not so many fixes since the release of 5.3.1, but it looks enough to release a new minor version from branch 5.3. I am planning to do in on Thursday, Jan 9, 2020, if there are no new reports of relevant issues that make us to reconsider and postpone.
Soon after we should probably do a release from branch 5.2 as well as the last one from branch 5.1.
Cheers, Daniel
