Fedora Linux 45 Ships Reproducible Builds by Default
The new stable release brings Linux 7.2, GNOME 51, and KDE Plasma 6.8 to shipped ISO images available now.
Updated on Nov. 3, 2026 in Software
Fedora Project released Fedora Linux 45 as its latest stable version on November 3, 2026, with existing Fedora Linux 44 users able to upgrade via DNF system-upgrade. The release is a shipped product available as live ISO images from Fedora mirrors.
Why it matters
The release arrives six months after Fedora Linux 44, keeping Fedora on its regular semiannual cadence. It bundles a newer kernel line and default desktop environments alongside reproducibility and security defaults that push a community distribution toward verifiable builds.
The release ships the Linux 7.2 kernel series with GCC 16.2, LLVM 23, Go 1.27, Python 3.15, and Podman 6 as bundled toolchains and runtimes. Benchmark figures comparing these components with Fedora Linux 44 were not reported in the source material.
The players
Fedora Project
Fedora Project is the community steward of Fedora Linux, a Red Hat-sponsored distribution whose releases serve as an upstream proving ground for RPM-based Linux tooling.
The details
Fedora Linux 45 includes fully reproducible package builds, meaning the same source inputs produce byte-identical packages so independent parties can verify that a binary matches its source. RPM signature checking is enabled by default, so packages are verified against cryptographic signatures before installation. The release also switches the default Secrets Service provider on Fedora desktops to oo7 and moves packaged RPM repository configuration from /etc to /usr, a change that separates vendor defaults from administrator overrides.
Timeline
Fedora Linux 44 was released six months before Fedora Linux 45.
Fedora Linux 45 became available for download on November 3, 2026.
The Tech Race
Fedora Linux 45 follows the six-month cycle established by Fedora Linux 44 and sits alongside other Linux distributions competing on default security and reproducibility features. The release's emphasis on verifiable package builds reflects a broader push in open-source software supply chains, though the source does not name a specific competing effort.
Users of Fedora Linux 44 can upgrade in place using DNF system-upgrade, and new installs can use the live ISO images from Fedora mirrors. Desktop users will see GNOME 51 or KDE Plasma 6.8 depending on the edition they choose, and the source does not specify any hardware prerequisites beyond the existing installer requirements.
The takeaway
Fedora Linux 45's reproducible builds and signature checking by default show distributions treating supply-chain verification as a baseline rather than an option. Watch the Fedora Linux 46 cycle, expected on the six-month cadence set by Fedora Linux 44 and 45, for whether these defaults expand further.
