 Scheduled Release 8.2306.0 (aka 2023.06) 2023-06-??
+- 2023-06-16: imjournal: Add FileCreateMode module parameter
+    FileCreateMode allows to set the default file mode bits
+    when creating new files. As of now, it has only impact on the state file.
+    Add test suite as well.
+    Minor indentation fix in run_journal.yml
+  Thanks to Attila Lakatos for the patch.
+- 2023-06-16: core bugfix: potential segfault on busy systems
+  This was discovered by Konstantin J. Chernov in a practicaly deployment.
+  Here, msg object tag processing caused sporadic segfaults. We did not
+  hear from similiar cases, but there clearly is potential for problems
+  because a mutex lock had insufficient range, thus leading to a potential
+  race.
+  The patch is directly from Konstantin J. Chernov, thanks for that.
+  Please note that the mutex lock could be minimized as it is not strictly
+  needed for the pM == NULL case, but this cause is extremely exotic
+  and the resulting code would be harder to understand. Thus we opt
+  to do the locking on funtion level (as usual).
+  Descriptiond edited by Rainer Gerhards
+  closes: https://github.com/rsyslog/rsyslog/issues/5110
+- 2023-06-16: Add new global config option "libcapng.default"
+  Defines how rsyslog should behave in case something went wrong
+  when capabilities were to be dropped. Default value is "on",
+  in which case rsyslog exits on a libcapng related error.
+  Thanks to Attila Lakatos for the patch.
+  Closes https://github.com/rsyslog/rsyslog/issues/5096
 - 2023-06-05: imfile bugfix: file handle leak, primarily in kubernetes context
   At this point there is a code imfile.c#L919 that adds an inotify observer to the
   parent of the symbolic link target. But there is no such code that removes this
