What would a deadline be without a delay? Sadly, we felt that we were not quite ready to unleash beta 3 today. Rather than unleashing software that isn’t ready, we’re opting to delay beta 3.
We’re taking a look at where we stand and we hope to be able to finish it for next week. I’ll post about an update hopefully tomorrow.

Sorry if I’m sounding dumb but is beta what we can see in test.musicbrainz.org ?
