+  - Fixed a bug that could cause the damon to crash when outgoing server
+    connections can't be established.
   - Fixed a bug that caused the daemon to leak file descriptors when no
     resolver subprocesses could be created.
   - Fixed server NOTICEs to users with "s" mode ("server messages").
