Fedora has released the Fedora Linux 45 Beta on September 15, 2026, providing testers with a nearly complete preview ahead of the final release scheduled for October 2026. This beta version includes significant updates such as a new userspace kmscon console, enforced package signature checking, and restricted ptrace access for unprivileged users, alongside numerous toolchain updates. The Fedora Asahi Remix 45 Beta has also been launched, featuring out-of-the-box support for Apple M3 Macs, although full GPU driver support will come later through an update. The beta is available for download across various editions and allows users to upgrade existing systems using DNF

Fedora Linux 45 Beta Released Ahead of October Launch

Fedora shipped the Fedora Linux 45 Beta on September 15, 2026, handing testers a nearly complete preview roughly six months before the final October release. The beta is identical to the September 5 third candidate, meaning it locks in already-approved features rather than rolling out a fresh change set. Headline updates include the userspace kmscon console replacing legacy fbcon, enforced package signature checking, restricted ptrace access for unprivileged users, and a wave of toolchain bumps spanning Python 3.15, Go 1.27, GCC 16.2, and glibc 2.44. It's downloadable in nearly every edition and upgradable from an existing system via DNF, while the companion Asahi Remix adds out-of-the-box support for Apple M3 Macs.
