core_role (subsystem) Upgrade notes

4.5

Added

• All session management has been moved to the \core\session\manager class. This removes the dependancy to use the sessions table.

  Session management plugins (like Redis) should now inherit the base \core\session\handler class, which implements SessionHandlerInterface, and override methods as required.

  The following methods in \core\session\manager have been deprecated:

  Old method name	New method name
  kill_all_sessions	destroy_all
  kill_session	destroy
  kill_sessions_for_auth_plugin	destroy_by_auth_plugin
  kill_user_sessions	destroy_user_sessions
