 ### Fixes
 
+- Discord: add exec approval cleanup option to delete DMs after approval/denial/timeout. (#13205) Thanks @thewilloftheshadow.
 - Sessions: prune stale entries, cap session store size, rotate large stores, accept duration/size thresholds, default to warn-only maintenance, and prune cron run sessions after retention windows. (#13083) Thanks @skyfallsin, @Glucksberg, @gumadeiras.
 - CI: Implement pipeline and workflow order. Thanks @quotentiroler.
 - WhatsApp: preserve original filenames for inbound documents. (#12691) Thanks @akramcodez.
