Currently changes for both branches 'next' and 'master' are sent to musicbrainz-commits mailing list.
We agreed during the last developer meeting (http://chatlogs.musicbrainz.org/musicbrainz-devel/2010/2010-04/2010-04-05.html#T19-33-23-796407) to only notify changes for 'master' branch.
I don't know how to implement this. Will happily take a patch. Current script is here:
Olivier, could you explain us the changes that are required?
I don't think that's intentional, but now we don't have any notifications at all: neither master nor next
Aurélien, etc.: is this ticket still valid, or has it been fixed/superseded in some fashion?
I'm not following anymore musicbrainz-commits, so I'm not the better qualified person to reply.
Said differently: you can safely close this ticket as WONTFIX.
