Deprecated methods LLMS_Admin_Notices_Core::sidebar_support() and LLMS_Admin_Notices_Core::clear_sidebar_notice().
Removed notice for theme sidebar support.

The function llms_is_user_enrolled() will always return false for non existing users. While, before, it could return true if a now removed user was enrolled into a the given course or membership.
Added new LLMS_Course::get_lessons_count() method. It can be used in place of count( LLMS_Course::get_lessons() ) to improve performance.
Fixed compatibility with PHP 8.1 by using an empty string as menu parent page for the course builder submenu page in place of NULL.
Avoid passing null values to urlencode() and urldecode() that would produce PHP warnings on PHP 8.1+.
Added $autoload parameter to the function llms_get_student.

Improve performance when querying notifications via the LLMSNotificationsQuery and there’s no need to count the total notifications found, or for pagination information.
Immediately return false when running llms_is_user_enrolled() on logged out or no longer existing users, avoiding running additional DB queries e.g. when displaying course or membership catalogs for visitors.
Skip counting the total transactions found when retrieving the last or the first transaction for an order.
