sabre/event 2.0.1 release

We just released sabre/event 2.0.1.

This release fixes two issues related to the EventEmitter::once() method, and brings its functionality up to par with EventEmitter::on().

Upgrade sabre/event by running:

composer update sabre/event

If this didn't upgrade you to 2.0.1, make sure that your composer.json file has a line that looks like this:

"sabre/event" : "~2.0.1"
