@avivr Hey! Thanks for the PR! I think we can simplify this a lot for the first changelog. What do you say @okonet ?

[evenstensberg]

Hey Aviv! I'd suggest you just to put up a blank one for us to fill. Found a default one at webpack-defaults. Thanks!

thanks for the feedback @ev1stensberg , i wasn't aware of webpack-defaults.
I changed it to match the CHANGELOG from the templates folder, hope that's what you meant.

[evenstensberg]

Yup! I'll push some changes to this branch later, and I'll merge :)

Hmm, seems like you didn't join the collab list. Sorry about that @avivr .. Could you make a new PR for v.1.3.1 using https://github.com/conventional-changelog/standard-version ? Seems like they generated the same changelog as in the initial PR, but I cut some commits that weren't needed there.
