Hyatt made the announcement on his blog. Using bugzilla, and cvs. It says it’s even possible to get checkin access if your a contributor with a proven track record. I didn’t see any lxr like tool for viewing source via the web (very handy), or a list of reviewers. Perhaps that’s still to come, the website looks pretty new.
Anyway, congrats to the Safari team in addressing all those concerns a few weeks ago.
I’m curious how perhaps this can improve browser relations across the board. Not that the Safari team and Mozilla are so distant to begin with, but this could lead to bigger better things. This is great news for everyone.
