1/ I know this means we won't have much development release, but I
think we should keep our 6 months rhythm.
2/ For the major release, the time between the tarball availability is
increased from 3 days to 6 days, to leave us enough time to produce
binaries: Linux packages, Windows installer and OSX bundle.
3/ Time between the last bugfixes-only releases is increased from 2 to
3 weeks, to have more time for users to test them and provide feedback
and bug reports.
