Hello again! Just a quick update: I’ve set up the new fancy split domains, and put them up on Transifex for reviewing by interested parties. The default ‘server’ domain hasn’t been updated yet, since I’m still working on migrating translations to the new system, but the splits, and the contents of all the other domains, can be seen at https://www.transifex.net/projects/p/musicbrainz/. You’ll also see a new ‘picard’ domain, for translation of MusicBrainz Picard. Thanks to Lukáš Lalinský for migrating that to the same place as musicbrainz-server translations; hopefully Picard can benefit from some of the new split domains!
I hope to update again shortly, once the translations are migrated to the new system (and once musicbrainz-server knows how to use these new domains).
