Fedora Linux 41 was released today [[1]]. The Fedora CoreOS `testing` stream has been rebased and is currently rolling out. In two weeks, it will be promoted to the `stable` stream.

For more information about Fedora 41, see the Fedora Project’s list of official Changes [[2]] and the Fedora CoreOS analysis of each Change [[3]].

The following changes require special attention:

- Fedora CoreOS is dropping Wi-Fi firmware packages that were split into subpackages of linux-firmware [[4]]. If you are currently using Wi-Fi, see the documentation for how to keep it enabled [[5]].
- Composefs is now enabled by default [[6]]. Pay special attention to the known issues [[7]].
- In systemd v256 cgroups v1 support was disabled. If you’ve opted out of the cgroups v2 migration in the past, your system will fail to boot after upgrading.
- moby-engine/Docker was updated in Fedora from version 24 to version 27. Please see the notes [[8]] with each release of moby and also the deprecated/removed features page [[9]] to see if there is any noteworthy changes for your use cases.

Please test out the `testing` stream and report any issues in our issue tracker [[10]].

Thank you to everyone helping find issues by running the `next` and `testing` streams!
