At the top of the sidebar is a link to a directory in web space of mine. The zip file currently there is up-to-date code from SVN and it contains the /wp-admin, /wp-includes and root files. It IS beta code and it does need testing so if you want to grab and do that, great. If you want to hang on for the official word, that’s okay too. I’ve been using it here for several days now and all is good but the usual caveats apply – backup, if bad things happen it’s not my fault, report plugin problems etc. I’m not saying how to upgrade. I’ll post a new zip a day IF the code has changed and until there is a more official download location.
