 ## Bug Fixes
 
+- An issue with some stations crashing shortly after startup has been resolved. This was caused by a safety check we
+  added to the AutoDJ to check that AzuraCast was up and running at the same time; however, this caused issues with

+
 - We have identified an issue that would prevent backups from older than a few months ago from restoring correctly; this
   issue has been resolved, so backups should now restore without any issue regardless of the backup's age.
 
+- Several issues causing slowness in the Listener Report (especially the CSV generation) have been improved, so stations
+  with large listener counts should still be able to take advantage of this report in more scenarios.
