There will obviously be issues with any beta version so to save support time could we list things here?
 
If you havn't reported something _please do use the support system as well_.
 
 
File "admin/admin_layout_scheme.php"
missing in " Settings > System > Global Settings" when selecting "Change Active Scheme" in "Active Layout"

This has now been fixed and a new version of "admin/admin_global_settings.php" should be in the archive?

In Administration > Dashboard > Common Tasks clicking on "Change Active Scheme" gives admin/admin_layouts.php file not found.
 
Now fixed with a new "admin/admin.html" file.
