sc-controller, the Linux user-mode driver for the Steam- and other controllers (eg. DS4/DS5), has been released in version 0.6.4 - shortly after version 0.6.3.

This is a pure hotfix release: hidraw-pure conflicted with hidapi, breaking tools like liquidctl which rely on hidapi’s hidraw backend. Only system installations via a package manager are affected - users of the AppImage or a source install are not impacted.

This hotfix is only relevant for system installations via a package manager, the fixed issue does not affect you if you are using the AppImage or running from source.

Hotfix release due to hidraw-pure conflicting with hidapi, breaking tools like liquidctl which relied on the hidraw backend from hidapi if it was detected available.

The library is now attempted to be loaded via:

1. hidraw_pure - futureproofing, currently does not exist
2. hidraw - current v1.2
3. Finally, the re-vendored version is used if all fails.

The dependencies are now also correctly defined in pyproject.toml, so pip check works correctly.
