2. Opening form tag was missing on tree template in admin.

3. #27461 - Admin: Browse Modes -> Section Properties for Items

4. Now c_CategoryLink tag builds link to category using it's path as template, not actual design template as before (as result was have identical links in menu and in category listing).

5. New method kEventManager::openerStackChange for changing last element of current window's opener stack.

6. Don't autocreate missing system pages, when user browses to them, like design pages (because they could intensionally not created in structure via .smsignore file).
