CHANGELOG.md

@@ -9,6 +9,7 @@ Docs: https://docs.openclaw.ai
 - Sandbox: add `sandbox.browser.binds` to configure browser-container bind mounts separately from exec containers. (#16230) Thanks @seheepeak.
 - Discord: add debug logging for message routing decisions to improve `--debug` tracing. (#16202) Thanks @jayleekr.
 - Discord: allow exec approval prompts to target channels or both DM+channel via `channels.discord.execApprovals.target`. (#16051) Thanks @leonnardo.
+- Slack/Discord: add `dmPolicy` + `allowFrom` config aliases for DM access control; legacy `dm.policy` + `dm.allowFrom` keys remain supported and `openclaw doctor --fix` can migrate them.
 - Telegram: add poll sending via `openclaw message poll` (duration seconds, silent delivery, anonymity controls). (#16209) Thanks @robbyczgw-cla.
