- Fixed core server bugs: safe maintenance‑mode leader transfer, corrected default quorum replica count, reduced idle CPU usage, and prevented early‑boot memory monitor errors.
- Added enhancements: stricter TLS certificate validation, new `rabbitmqctl close all user connections` CLI command, extra LDAP TLS options, and support for queue‑argument specification in dynamic Shovels.
- Updated Prometheus metrics to remove duplicate TYPE/HELP strings and fixed hostname resolution bug in the Erlang client.
