What do you know about libmusicbrainz4c2a? It appears to be a new version of the MusicBrainz library but then again it isn’t. What is the state of MusicBrainz development and how did we end up with a version with a 4 appended that appears to be based on version 2? Thought you might know something about this having worked with so much and for so long.
Version 4? - libmusicbrainz4c2a
Sorry no idea.
