How do you remove listeners?

[frugan-dev]

In version 2 there were these methods to remove listeners:

$emitter->removeListener($event, $listener);
$emitter->removeAllListeners($event);

How to do it in version 3?

Here we mention the matter, but always with reference to version 2.

It seems that other similar libraries have these methods:

https://github.com/symfony/event-dispatcher/blob/6.2/EventDispatcher.php#L132
https://github.com/laminas/laminas-eventmanager/blob/3.10.x/src/EventManager.php#L202
https://github.com/laminas/laminas-eventmanager/blob/3.10.x/src/EventManager.php#L250

Thanks!
