5.6 is out, rejoice! This means we're going to start emailing patches for 5.6 instead of 5.5, though of course 5.5 patches will be available via the website. It also means 5.4 has officially been retired and won't be receiving any more patches.
When upgrading, take a moment to review the 5.6 errata page. The first two patches weren't previously announced, as they only apply to 5.6 and not 5.5. The remaining three were previously announced, but too late to make it into the 5.6 release. http://www.openbsd.org/errata56.html
