In
one week, 2025-07-29, or slightly later, I plan to update the uv
package from 0.7.22 to 0.8.0 or a later 0.8.x release[1] in Fedora
Rawhide, 42, and 41. I also plan to ship the same update to the
EPEL10 leading branch, currently EPEL 10.1.
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.” The exact changes are documented in the
release notes for 0.8.0[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
will continue to 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.
I
will also update python-uv-build[5], 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.
