Starting today, we're going to try sending patches out via email so you don't miss them.
Several previous errata have also been recently published for OpenBSD 5.4 and 5.5. We won't be mailing them out individually since they aren't new, but you should check the web site for details. Refer to http://www.openbsd.org/errata55.html and errata54.html. (Also note that OpenBSD 5.3 is officially end of life and will not be receiving any more patches.)
