Full Release Notes

## Fixed

* [#5959](https://github.com/firecracker-microvm/firecracker/pull/5959): Reverted the use of `O_NOFOLLOW` for the jailer's cgroup and network namespace file operations, so symlinks are again allowed in these paths.
* [#5958](https://github.com/firecracker-microvm/firecracker/pull/5958): Fixed a bug that caused vsock guest-to-host connections to time out after snapshot restore, triggered by taking a snapshot with a TX descriptor in-flight. On restore the device now replays the TX queue notification so in-flight TX descriptors are re-processed and notification suppression is re-armed.
