We now user $CFG->navcourselimit to limit the number of
courses shown in the navigation when browsing another users
full profile. Previously it showed all courses which caused
some slowdown.
Under certain conditions, coding exception is thrown when fetching items from
the navigation bar. The patch prevents them. See more details in the tracker.
* Navigation/settings now show best available option.
* Resorting categories works now for limited access user.
* Display of up and down arrows corrected.
* Checkboxes no longer displayed if an action can't be performed.
* Implemented a new course and category management page.
* Deprecated the old management interface.
* Unit tests to cover the new API and core functions.
* Behat tests to cover the new interface.
* Added new constant: MOD_SUBTYPE_NO_CHILDREN
* When MOD_SUBTYPE_NO_CHILDREN is returned from xxx_get_types()
then default display is used for activity chooser.
* Updated mod/upgrade.txt

it for new behavior of xxx_get_types
* Updated lib/upgrade.txt
List of changes:
