 ## Bugs
 
-- Fixed an issue where ephemeral runners deregistered themselves when jobs were not successful (#1384)
-- Fixed an issue where you were not able to un-configure a runner that changed groups (#1359)
-- Disable `stop-commands` command using well known keywords as a token (#1371)
+- Fixed an issue where ephemeral runners did not restart after upgrading (#1396)
 
 ## Misc
 
-- Don't retry 422 error codes when downloading actions (#1352)
-- Handle upgrade more smoothly on OSX (#1381)
-
 ## Windows x64
 We recommend configuring the runner in a root folder of the Windows drive (e.g. "C:\actions-runner"). This will help avoid issues related to service identity folder permissions and long file path restrictions on Windows.
