==================
- Added possibility to specify custom item class in menuItem, subMenuItem
and addMenuItem directives using the ``item_class`` argument (LP 291865).
- Menu items registered with <browser:page/> were not re-registered after the
first functional test layer ran. In any subsequent functional test layer the
items where not availabe (introduced in 3.5.0a3).
- Added a hook to specify a different BaseURL for resources. This makes sense
if you want to put resources on a Content Delivery Network. All you need to
do is to register an named Adapter 'resource' that implements IAbsoluteURL.
