This is a bugfix release.


  • If the broker was configured for persistence, a durable client had a subscription to topics in $SYS/# and had messages in its queue when the broker restarted, then the persistent database would have messages missing and so the broker would not restart properly. This has been fixed.


  • Fix threading problem on some systems.


  • Close socket after test to prevent subsequent tests having problems.

Build scripts:

  • Install pskfile.example in CMake. Fixes bug #1037504.


  • Fix db_dump parameter printing message store and sub chunks.
