Breaking Changes

Known Issues on Erlang 19.0

An undocumented runtime metric change in Erlang 19.0 breaks management plugin.


Bug Fixes

  • (Newly elected) queue master process could terminate immediately after promotion

    GitHub issue: rabbitmq-server#812

  • Priority queue mirror could fail to synchronize after restart

    GitHub issues: rabbitmq-server#687, rabbitmq-server#802

  • Shutdown timeouts for worker processes are now much more reasonable.
    Earlier the timeouts were virtually infinite which could lead to a deadlock during node shutdown.

    GitHub issue: rabbitmq-server#541

  • Purging of a durable queue could result in undelivered publisher confirms.
    Contributed by Andreas Ländle.
