+# 2022-11-19
+
+-   Updated to Discord.js 14, removed Cookiecord to prevent future delays in updating versions.
+-   The bot will now react on the configured autorole messages to indicate available roles.
+-   Unhandled rejections will now only be ignored if `NODE_ENV` is set to `production`.
+-   Removed admin `checkThreads` command as using it would result in the bot checking for closed threads twice as often until restarted.

-**A quick note about the help channel system:** Please don't use it if you don't have a large server (10k+ members) as it will likely inconvenience your members rather than benefit them. We used a static channel system (#help-1 and #help-2) up until around 9,000 members, when we started to see issues arising (many questions being asked on top of eachother without answers).
