@francesco-corti Do we need an entry in the DD release notes about Ask Gordon public beta?

Yep, thank you.
I thought it was already there (my bad).

No worries. @aevesdocker Could you add an entry for Ask Gordon and point to the beta docs - https://docs.docker.com/desktop/features/gordon/?


- Installing Docker Desktop via the PKG installer is now generally available.
- Enforcing sign in via configuration profiles is now generally available.
- Docker Compose, Docker Scout, the Docker CLI, and Ask Gordon can now be updated independently of Docker Desktop and without a full restart (Beta).
- The new `update` command has been added to the Docker Desktop CLI (Mac only).
- [Bake](/manuals//build/bake/_index.md) is now GA, with support for entitlements and composable attributes.

### Bug fixes and enhancements

#### For all platforms

- Fixed a bug where access tokens generated by the `docker login` web flow could not be refreshed by Docker Desktop.
- Fixed a bug where container creation via the Docker API using `curl` failed when [Enhanced Container Isolation](/manuals/security/for-admins/hardened-desktop/enhanced-container-isolation/_index.md) was enabled.
- Fixed a bug where the RAM policy was not refreshed after the refresh period had elapsed.
- Fixed a bug in Enhanced Container Isolation when mounting the Docker socket into a container, and then creating Docker containers with bind-mounts from within that container.
- Fixed an issue that caused a discrepancy between the GUI and the CLI, the former forcing the `0.0.0.0` HostIP in port-mappings. This caused default binding IPs configured through Engine's `ip` flag, or through the bridge option `com.docker.network.bridge.host_binding_ipv4`, to not be used.
- Fixed a bug where the `pac` setting was ignored in `admin-settings.json`.

#### For Mac

- Fixed a bug in Docker VMM where bind-mounts from non-root volumes would weren't working as expected.

- Fixed an issue where Docker Desktop would fail to start for data disks created with old WSL versions that shared the same identifier as other WSL distros.
- Docker Desktop now restarts when WSL integration settings are changed. This ensures proper setup of WSL integration when using Enhanced Container Isolation.

#### For Linux

- Added support for gvisor networking. Users with an incompatible version of qemu (8.x) will stay on qemu networking, and others will be migrated automatically.
