I’ve just released Pykka 2.0. Pykka is the concurrency library that both Mopidy and all Mopidy extensions are built on top of.
Mopidy and existing extensions should work with Pykka 2.0 without any code changes. However, test suite speed and Mopidy’s startup performance should be greatly improved.
If you give it a try and run into any bugs, let me know in GitHub issues.
