Suggested change
- Re-enable `seccomp` for containers
- Re-enable `seccomp` for containers by default. Use `docker run --security-opt seccomp=unconfined` to disable seccomp for a container.

(in case it causes a problem, this would be a workaround)

- 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 to align with the full capacity of the host file system.

Suggested change
- Fixed a bug in the Dashboard container logs screen causing the scrollbar to disappear as the mouse approaches.

We've had a decent number of complaints about this bug in the feedback, but I haven't seen any on github.
(We attempted to include this note in https://github.com/docker/pinata/pull/34611 but I'm guessing it got filtered out because the wording didn't make it sound interesting?)

#### For Mac

- Fixed a bug where the disk would always have a minimum usage limit of 64GB when using Docker VMM.
