Why did SWI-Prolog move to GIT?

The SWI-Prolog project moved from CVS to GIT because

• CVS started to become too slow
• CVS doesn't support staging very well. I like frequent commits to synchronise between machines, commit work that is known to be incomplete, etc. For GIT this is the natural model, for CVS it is just too cumbersome.
• GIT allows for offline working.
• GIT checkouts are totally stand alone, making local branches much easier as well as providing security against system failure, etc.

Sofar, we are very happy with this move. Recent system failures have indeed proved that the distributed approach allows to restoring the central repository from the development systems easily.
