Update description:

Update uv from 0.4.30 to 0.5.5. This is a significant update. Please see the following notes.

By updating to a current release of uv, this update fixes CVE-2024-53899, which was originally reported against virtualenv but which was also reproducible on uv 0.5.2 and earlier. See upstream issue #9424 for more details.

This update adds a default system-wide configuration file /etc/uv/uv.toml with settings specific to Fedora. The RPM-packaged uv now deviates from the default configuration in two ways.

First, we set “python-downloads” to “manual” in order to avoid unintended Python downloads. We suggest using RPM-packaged (system) Pythons that benefit from distribution maintenance and integration. Use uv python install to manually install managed Pythons.

Second, we set “python-preference” to “system” instead of “managed”. Otherwise, any managed Python would be used for uv operations where no particular Python is specified, even if the only available managed Python were much older than the primary system Python.

No choices can be appropriate for all users and applications. To restore the default behavior, comment out settings in this file or override them in a configuration file with higher precedence, such as a user-level configuration file. See https://docs.astral.sh/uv/configuration/files/ for details on the interaction of project-, user-, and system-level configuration files.

With 0.5.0, uv introduced several potentially breaking changes. The developers write that these are “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.”

Use base executable to set virtualenv Python path
Use XDG (i.e. ~/.local/bin) instead of the Cargo home directory in the installer
Discover and respect .python-version files in parent directories
Error when disallowed settings are defined in uv.toml
Implement PEP 440-compliant local version semantics
Treat the base Conda environment as a system environment
Do not allow pre-releases when the != operator is used
Prefer USERPROFILE over FOLDERID_Profile when selecting a home directory on Windows
Improve interactions between color environment variables and CLI options
Make allow-insecure-host a global option
Only write .python-version files during uv init for workspace members if the version differs
