Thank you for the PR. This is a silly thing that I missed to fix :D
But changing this will be a breaking change.

[qjcg]

Fair enough. My view is that misspellings in the public API can confuse and frustrate developers and convey a sense of lower code quality, and therefore merit a breaking change, but the choice is up to you of course

[bxcodec]

Alright then, I think it's better to merge it for now, and for the better quality ;)

[qjcg]

Awesome, thanks and keep up the great work with this library!
