-# Upgrade to 2.0
-
-## Made the `$event` parameter of `EventManager::getListeners()` mandatory
-
-When calling `EventManager::getListeners()` you need to specify the event that
-you want to fetch the listeners for. Call `getAllListeners()` instead if you
-want to access the listeners of all events.
-
-# Upgrade to 1.2
-
-## Deprecated calling `EventManager::getListeners()` without an event name
-
-When calling `EventManager::getListeners()` without an event name, all
-listeners were returned, keyed by event name. A new method `getAllListeners()`
-has been added to provide this functionality. It should be used instead.
