* ultrastardx-beta: init at 1.3.5 * libbass, libbass_fx: init at 24 * ultrastar-creator: init at 2017-04-12 * buildSupport/plugins.nix: add diffPlugins Helper function to compare expected plugin lists to the found plugins. * ultrastar-manager: init at 2017-05-24 The plugins are built in their own derivations, speeding up (re-)compilation. The `diffPlugins` function from `beets` is reused to test for changes in the plugin list on updates. * beets: switch to diffPlugins The function is basically just extracted for better reusability.
