currently there seems to be not enough stuff going on to justify weekly releases, plus there seemed to be a tendency (proven by your own post ) to consider "update" releases as "unstable" when they often were not.
given that contributors and people interested to use bleeding edge code can anyway just take the source from the svn/git mirrors, the new policy is to just have new full releases every 5-6 weeks (or when there is enough new material to justify a new "main" version)
