   ## Improvements
 
   - [Slack agent](/agent/slack) now requests permission requests to run third-party action such as sending an email or creating a ticket.
+  - The agent side panel in the [editor](/editor/collaborate#browse-agent-chat-history) now has a chat history view, so you can revisit past chats, jump back into chats still running in the background, and see which conversations have unread agent messages.
   - The [editor](/editor) now lets you drag images and videos from the navigation tree directly onto a page to embed existing media inline.
   - Mermaid diagrams in the editor now support a fullscreen mode for easier editing of complex diagrams.
   - The custom domain dashboard now displays both verification `TXT` records (`_acme-challenge` and `_cf-custom-hostname`) with live verification status, so you can confirm DNS is correct before pointing your `CNAME` at Mintlify. See [custom domain](/customize/custom-domain) for more details.

+## Browse agent chat history
+
+The agent side panel keeps a history of past chats so you can revisit earlier conversations, pick up where you left off, or check on chats that are still running in the background.
+
+To open chat history:
+
+1. Open the agent side panel in the editor.
+2. Click the clock icon in the panel header to switch from the chat view to the history view.
+3. Click any row to load that chat's messages back into the panel.
+4. Click **Back** in the header to return to your current chat.
+
+Each history row shows the first message you sent, the branch the chat ran on, and how long ago it started. A spinner indicates a chat that is still running, and a green dot indicates a finished chat with unread agent messages. Rows for the branch you currently have open are highlighted so you can find related work quickly.
+
+Start a fresh chat at any time by switching back to the chat view and clicking **New chat** in the header.

 ## Branch-based collaboration
 
 Use branches to work on documentation updates in parallel without affecting your live site. If you aren't familiar with Git, see [Git essentials for the web editor](/editor/git-essentials).
