+### Bug fixes and enhancements
+
+#### For all platforms
+
+- Docker Desktop now accepts certificates with a negative serial number.
+- Re-enable `seccomp` for containers by default. Use `docker run --security-opt seccomp=unconfined` to disable seccomp for a container.
+- Fixed a bug that caused Docker Desktop to hang when it ran out of memory.
+- Block `io_uring` syscalls in containers.
+- Added support for pulling models from Docker Hub directly, simplifying the process of accessing and using models.
+- Docker Desktop now sets the disk usage limit to the size of the physical disk on fresh install and reset to defaults on Mac and Linux.
+- The maximum disk size in the settings UI now aligns with the full capacity of the host file system.
+- The **Models** view now has a **Docker Hub** tab that lists models under the `ai` namespace.
+- Improved the sign-in enforcement message when more than 10 organizations are enforced.
+- Changed the way ports are mapped by Docker Desktop to fully support IPv6 ports.
+- Fixed a bug in the Dashboard container logs screen causing the scrollbar to disappear as the mouse approaches.
+- [Enforced sign-in](../security/for-admins/enforce-sign-in) fixed for Teams subscription users.
+- `llama.cpp` server now supports streaming and tool calling in Model Runner.
+- Sign-in Enforcement capability is now available to all subscriptions.
+
+#### For Mac
+
+- Fixed a bug where the disk would always have a minimum usage limit of 64GB when using Docker VMM.
+- Disabled the memory protection keys mechanism in the Docker Desktop Linux VM. This caused VS Code Dev Containers to not work properly. See [docker/for-mac#7667](https://github.com/docker/for-mac/issues/7667).
+- Fixed persistent volume claims under Kubernetes. Fixes [docker/for-mac#7625](https://github.com/docker/for-mac/issues/7625).
+- Fixed a bug where the VM failed to start using Apple virtualization.framework.
+- Minimum version to install or update Docker Desktop on is now macOS Ventura 13.3.
+
+#### For Windows
+
+- Fixed a bug in Enhanced Container Isolation on Windows WSL, where files with hardlinks inside containers had `nobody:nogroup` ownership.
+- Fixed a bug that caused Docker Desktop to crash. Related to [docker/for-win#14782](https://github.com/docker/for-win/issues/14782).
+- Fixed a bug that caused `The network name cannot be found` error when starting with WSL 2. Fixes [docker/for-win#14714](https://github.com/docker/for-win/issues/14714).
+- Fixed an issue where Docker Desktop would not remove entries in the hosts file when uninstalling.
+- Fixed an issue when reading auto-start registry key for some system languages. Fixes [docker/for-win#14731](https://github.com/docker/for-win/issues/14731).
+- Fixed a bug where Docker Desktop was adding unrecognised /etc/wsl.conf `crossDistro` option which was causing WSL 2 to log an error. See [microsoft/WSL#4577](https://github.com/microsoft/WSL/issues/4577)
+- Fixed a bug where Docker Desktop failed to start on WSL 2.5.7 if another WSL distro is still using Linux cgroups v1. Fixes [docker/for-win#14801](https://github.com/docker/for-win/issues/14801)
+- Windows Subsystem for Linux (WSL) version 2.1.5 is now the minimum version required for proper functioning of Docker Desktop application
+
+### Known issues
+
+#### For Windows
+
+- Running containers with Wasm will hang sporadically. See [docker/for-mac#7666](https://github.com/docker/for-mac/issues/7666).
+- On some machines Resource Saver will cause other WSL 2 distros to freeze. The workaround is to disable Resource Saver. See [docker/for-mac#14656](https://github.com/docker/for-win/issues/14656).
