It
appears as if William Yodlowsky(william@) has been silently committing updates to OPENBSD_4_5.
Here is a list of ports that have received updates, or so I've found.
No binary packages are available yet, but you can most definitely build your own.
Define CVSROOT first, export with bourne shells.. env with csh shells.
$ cd /usr/ports; sudo cvs up -r OPENBSD_4_5 -Pd
I consider this good news.
