There have been around 50 "core" developers with full commit access and
decision-making power, and a Technical Board to act as a tie-breaker.
But this wasn't how the project actually worked -- most "core"
developers were inactive, and most decisions were made by consensus on
the django-developers mailing list or in the bug tracker. So we are
moving to a system that formally recognizes this, and officially
adopts a more open, consensus-based process that does away with the
special group of "core" developers. Since this is mostly just saying
officially that they'll do things the way they've been working, users of
Django probably will not notice any change :)
