 - Model config schema changes (auth profiles + model lists); doctor auto-migrates and the gateway rewrites legacy configs on startup.
 - Commands: gate all slash commands to authorized senders; add `/compact` to manually compact session context.
 - Groups: `whatsapp.groups`, `telegram.groups`, and `imessage.groups` now act as allowlists when set. Add `"*"` to keep allow-all behavior.
+- Auto-reply: removed `autoReply` from Discord/Slack/Telegram channel configs; use `requireMention` instead (Telegram topics now support `requireMention` overrides).
 
 ### Fixes
 - Pairing: generate DM pairing codes with CSPRNG, expire pending codes after 1 hour, and avoid re-sending codes for already pending requests.
