+#### For all platforms 
+
+- Fixed an issue where kind cluster state is sometimes reset when Desktop restarts. Fixes [docker/for-mac#77445](https://github.com/docker/for-mac/issues/7745).
+- Removed the obsolete `mcp` key to align with the latest VS Code MCP server changes.
+- Update credential helpers to [v0.9.4](https://github.com/docker/docker-credential-helpers/releases/tag/v0.9.4).
+- Fixed an issue where Docker Desktop used an expired proxy password while waiting for the user to enter a new one. 
+- Fixed a bug which caused Docker Desktop to regularly create new processes with Docker CLI tools under certain conditions. Fixes [docker/for-win#14944](https://github.com/docker/for-win/issues/14944).
+
+#### For Windows
+
+- Removed the `HKLM\SOFTWARE\Docker Inc.\Docker\1.0` registry key. Look for `docker.exe` in the path to find out where Docker Desktop is installed instead.
+- Fixed startup in WSL 2 mode when IPv6 has been disabled.
