Compared to RC1, this release fixes a JS error that occurred when a status was submitted via AJAX and a PHP and SQL error that occurred when @mention suggestions were calculated.
The first release of FBSSTS. Should be stable, although there are still a few rough spots.
Tested in Firefox 3.6, Internet Explorer 8, Chrome 5, Opera 10.50, and Safari 4. Should work in earlier modern builds of these browsers too, although it may not work as well in IE6.
