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.

We have decided to cancel the releases initially planned for this week as we encountered an issue that needs more investigation [1]. The next Fedora CoreOS releases will be made early January 2024. We came across this issue late in the release cycle and it may impact updates on aarch64 systems. We thus decided to skip those releases to avoid the risk of failed updates during the end of the year period.
