Based on the discussions during the last online devel meeting, the plan is to release the next major version (Kamailio v5.4.0) around the mid of this summer.
Therefore I propose to freeze the development on Thursday, June 18, 2020. Then we will have about 4-6 weeks of testing before the release is out. Master will be unfrozen when the branch 5.4 is created (usually that was done after 3-4 weeks in the testing phase).
If you are planning to introduce new features in the 5.4 release series, be sure you push them to master branch or create a pull request till the freezing date.
If anyone else wants a different time line for 5.4.0 release, let us know and we can discuss on firstname.lastname@example.org mailing list to match the best for everyone.
