 - Telegram: add verbose raw-update logging for inbound Telegram updates. (#1597) Thanks @rohannagpal.
 
 ### Fixes
+- BlueBubbles: route phone-number targets to DMs, avoid leaking routing IDs, and auto-create missing DMs (Private API required). (#1751) Thanks @tyler6204. https://docs.clawd.bot/channels/bluebubbles
 - BlueBubbles: keep part-index GUIDs in reply tags when short IDs are missing.
 - Web UI: hide internal `message_id` hints in chat bubbles.
 - Web UI: show Stop button during active runs, swap back to New session when idle. (#1664) Thanks @ndbroadbent.

 - `chat_id:123`
 - `chat_identifier:...`
 - Direct handles: `+15555550123`, `user@example.com`
+  - If a direct handle does not have an existing DM chat, Clawdbot will create one via `POST /api/v1/chat/new`. This requires the BlueBubbles Private API to be enabled.
 
 ## Security
 - Webhook requests are authenticated by comparing `guid`/`password` query params or headers against `channels.bluebubbles.password`. Requests from `localhost` are also accepted.
