I downloaded and installed version 1.3-RC for WordPress MU this week. Download it here, if you want – - or wait for the final release to be coming soon!
Changes:
The main blog of the site doesn’t have to live at /blog/ if you’re using virtual hosts. #409
WordPress importer can now assign posts to other users. #435
The importer shouldn’t error on the foreach() loop when there’s only one author now #405
Privacy mode of new blog is stored properly. #423
Various cleanup patches by ktlee and momo360modena.
momo360modena gave the wpmu-* admin pages a nice facelift!
XMLRPC posting and the signup page are now disabled by default. They can be activated in the wpmu-options.php page. It is possible to change the xmlrpc setting for a particular blog by editing it via the wpmu-blogs.php page.
Individual blog’s upload quota can be edited on the edit blog page too.
