4.6.0 sonoma alpha 1

This alpha-quality release of Quod Libet supports MacOS Sonoma (and earlier versions).

It is not an official release from the Quod Libet team, and probably contains new bugs and limitations. If you run into one of these, please open an issue here, not on the quodlibet/quodlibet repository.

This release is unsigned, so you'll need to follow the steps in https://support.apple.com/guide/mac-help/open-a-mac-app-from-an-unidentified-developer-mh40616/mac to launch it for the first time.
