 ### Added
 
 - Added `rsconnect mcp-server` command to expose rsconnect-python functionality to
   LLM clients via the Model Context Protocol. The server provides a `get_command_info`
   tool that returns parameter schemas for any rsconnect command, allowing LLMs
   to more easily construct valid CLI commands.
 
-- support for deploying Holoviz Panel applications
+- You can now deploy Holoviz Panel applications. This requires Posit Connect release 2025.11.0
+  or later. Use `rsconnect deploy panel` to deploy, or `rsconnect write-manifest panel`
+  to create a manifest file.
