Since this version pulls themes from the hub, if you have custom branch themes you should copy any branch site themes up to the hub.
To access theme files in the hub, use the {THEME_HTTP} tag.
Example:
Instead of
<img src="themes/mytheme/logo.jpg" />
use
<img src="{THEME_HTTP}logo.jpg" />
If you can't update because it is asking for the source.php file, grab a svn version on index.php and copy it into your installation directory. It will forgo source.php until you finish the update. The current tarball has been updated with the fix.
