The Fedora Linux 43 Beta was released today [1]. The Fedora CoreOS `next` stream switch to Fedora 43 is delayed, but planned for later this week. For Fedora 43, Fedora CoreOS is switching exclusively to updates shipped via the quay.io container registry [2][3], as well as payloads that are built with a container runtime directly [4][5]. As a result, we need to run a migration on the last releases of Fedora 42-based CoreOS to switch over to verifying signatures on container pulls rather than signatures of OSTree commit objects [6]. This migration is happening in the `42.20250914.1.0` release on the `next` stream, rolling out over the next few days. The migration will also come to the `stable` and `testing` streams in the coming month prior to the rebase to Fedora 43.
As for Fedora 43 related changes you can see the full list of Fedora Project changes [7] and the Fedora CoreOS analysis of each change [8]. Aside from the OSTree repo related changes mentioned above, there are a few others we'd like to highlight: - The iptables-legacy RPM will be dropped. Any systems still using the iptables-legacy backend will be migrated to iptables-nft [9]. - The Qualcomm (qcom) dtb files on aarch64 (arm64) have been removed [10]. This helps ease the pressure surrounding our limited disk space in /boot. - The GRUB bootloader and shim software are now updated by default on every boot [11][12]. This ensures our bootloader stays up to date. Please test out the `next` stream over the coming month and report any issues in our issue tracker [13]. Thank you to everyone helping find issues by running the `next` stream!
