EPEL-ANNOUNCEUpdating uv from 0.6.17 to 0.7.x in all Fedora releases and in EPEL10 leading branch
In one week, 2025-05-18, or slightly later, I plan to update the uv package from 0.6.17 to 0.7.3 or a later 0.7.x release[1] in Fedora Rawhide, 42, and 41. (Fedora 40 will have reached its end-of-life by then.) I also plan to ship the same update to the EPEL10 leading branch, currently EPEL 10.1.
In upstream’s words, “This release contains various changes that improve correctness and user experience, but could break some workflows; many changes have been marked as breaking out of an abundance of caution. We expect most users to be able to upgrade without making changes.” The exact changes are documented in the release notes for 0.7.0[2].
For stable releases Fedora 42 and 41, this update is permitted under a permanent exception to the Updates Policy[3]; for the EPEL10 leading branch, it is permitted under a semi-permanent exception for versions up to 1.0[4]. For EPEL “stable” branches (epel10.0), current policy does not allow SemVer-breaking updates of uv or of the library-only Rust packages upon which it depends, so uv 0.6.17[5] will be the final uv release in EPEL10.0 for the foreseeable future.
Four packages in Fedora now depend on uv: fawltydeps, hatch, python-build, and python-tox-uv. A quick impact check using local mock builds did not reveal any incompatibilities. Additionally, a new dependency from translate-toolkit was found to be spurious, and I opened a PR to remove it[6].
I will also update python-uv-build[7], the new uv-based build backend, to the same version as uv. This package is still Rawhide-only for now. As long as nothing yet depends on it, I prefer to allow a little time for the ecosystem to work out any kinks before locking us into a particular minor release in stable branches.

An update for uv 0.7.5 will shortly be available in EPEL10 updates-testing[1]. This is formally an incompatible update from uv 0.6.17, permitted under a semi-permanent exception for uv versions up to 1.0 in the “leading” EPEL10 branch[2].
In upstream’s words, “This release contains various changes that improve correctness and user experience, but could break some workflows; many changes have been marked as breaking out of an abundance of caution. We expect most users to be able to upgrade without making changes.” The exact changes are documented in the release notes for 0.7.0[3].
In accordance with the updates policy, this update will be manually pushed to stable after no less than one week in the testing repository, and I will send another announcement at that time.

An update for uv 0.8.4 will shortly be available in the testing repository for EPEL 10.1[1]. This is (strictly speaking) an incompatible update from uv 0.7.22, permitted under a semi-permanent exception for uv versions up to 1.0 in the “leading” EPEL10 branch[2].
In upstream’s words, “Since we released uv 0.7.0 in April, we've accumulated various changes that improve correctness and user experience, but could break some workflows. This release contains those changes; many have been marked as breaking out of an abundance of caution. We expect most users to be able to upgrade without making changes.”
“This release also includes the stabilization of a couple uv python install features, which have been available under preview since late last year.”
The exact changes are documented in the release notes for 0.8.0[3].
