I really appreciate this project and your help, but this is not very nice behavior to your contributors. Not at all.

You should explicitly say next time that you'll do it on your own, rather than leaving someone else spent his free time on something which is gonna be tossed away. Not cool at all.

@Hotell I had some time so I thought instead of requesting more changes to your PR, I can finish it quicker and do a release. I didn't have write access to your branch, so I created a new branch based on your PR. I also gave attribution to you in my commit. The attribution was mistakenly lost on master because it was squashed instead of "rebase and merge" during merging.

I'm sorry this upset you, but it wasn't my intention.
