Fedora DNF4 exit, Epic lockdown, Nix CI and baselines

Fedora advanced a system-wide plan to retire the DNF4 stack and modularity for Fedora 46 while Ubuntu contributors debated Epic Games kernel lockdown requests for Easy Anti-Cheat. NixOS threads covered a stable CI release, an x86_64 baseline raise, manual localization, a mise CVE, and Fedora process and Bodhi maintenance questions.

Fedora 46 proposal retires DNF4 stack and modularity

A Fedora Change proposal on the devel list seeks to remove the entire DNF4 stack and Modularity in Fedora 46, forcing completion of the DNF5 transition. Thirteen messages from eight participants examined the system-wide change. Maintainers and users still depending on DNF4-era tooling would need to finish migration before the release.

Ubuntu weighs Epic Easy Anti-Cheat lockdown demands

Ubuntu Discourse hosts a nine-message thread on how the distribution should respond to Epic Games requests for OS lockdown features required by Easy Anti-Cheat and titles such as Fortnite. Seven participants discussed dual-boot arrangements and other replies. The outcome matters for users who want native Linux game support without accepting tighter kernel restrictions.

mise CVE allows untrusted local config override

The Nixpkgs security tracker logged CVE-2026-103929 (CVSS 7.8) in mise, where untrusted local configuration can override default shell arguments before version 2026.7.14. A single report recorded the issue. Users of the tool under Nix should update to close the local override path.

Gradient v2.0 reaches stable as NixOS CI

Gradient version 2.0 was announced stable on NixOS Discourse as a Nix CI system offering concurrent evaluation and builds with resource-aware scheduling. Twenty-four messages from nine participants followed the release. Projects seeking faster Nix continuous integration gain a newly stabilized option.

Pre-RFC on raising NixOS x86_64 baseline to v3

A pre-RFC on NixOS Discourse proposes gradually moving the x86_64 baseline to x86-64-v3 via an intermediate x86-64-v2 step, citing roughly one percent gains against older CPU support and doubled build and cache costs. Nineteen messages from twelve participants debated the trade-offs. The change would determine which hardware remains first-class for NixOS binaries and caches.

Proposal to localize the Nix reference manual

An external organization proposed translating the Nix reference manual through a separate Crowdin and GitHub setup. Thirteen messages from five participants raised governance and fragmentation concerns. Maintainers and readers of Nix documentation should watch whether translations remain under community control.

Fedora proposes Changes discussion only on devel list

A Fedora 46 Change proposal would confine Changes discussion to the devel mailing list and leave Discourse announcements read-only. The Discourse thread drew 181 messages from 44 participants and a lengthy debate on platform usability. Contributors who prefer web forums over mail would face a narrower channel for formal change feedback.

Bodhi maintenance and possible replacement

Fedora developers on the devel list examined Bodhi maintenance problems and whether to replace it standalone or through a larger workflow redesign involving Red Hat efforts. Five messages from four participants outlined the options. The fate of Bodhi affects how updates move through Fedora's release pipeline.
