As we're nearing release, please concentrate on testing (especially binary packages) and less on needless updates or new ports. Of course there's still time to check out that piece of software you maintain or use and make sure there are no important reliability/security fixes available...
The snapshots are in their usual place (use mirrors), ftp://ftp.openbsd.org/pub/OpenBSD/snapshots/packages/ Of course you must be running -current to use them. Help make the next release better! Submit problem reports and/or fixes to this list and the maintainers.
