MusicBrainz Server update, 2020-09-07

Beyond the restless conversion to React of edits’ display, this new release of MusicBrainz Server features the sidebar display of recordings’ acoustic information automatically computed by AcousticBrainz, and brings a handful of more discreet improvements and fixed bugs.

A new release of MusicBrainz Docker is also available that matches this update of MusicBrainz Server. See the release notes for update instructions.

Thanks to loujine for contributing the code to display AcousticBrainz data. Thanks to chaban, draconx, hawke, scotia, and yindesu for having reported bugs and suggested improvements. Thanks to kellnerd, mfmeulenbelt, salorock, and speardog for updating the translations (de, el, fr, it, nl). And thanks to all others who tested the beta version!
