I thought this is what we already do, its just in the 2.5 series we have
become very lazy in these regards, now that 2.5 is final and stable, we
should really adopt our old methodology again with no set freeze period,
we aim for a date and set freeze a few days before it, and only release
if the code is deemed releasable
