a changelog might be interesting for the wider audience. I'm following the language from afar and this is what would interest me.

I think this may be what you are looking for: https://github.com/nim-lang/Nim/blob/devel/changelog.md

It’s not exhaustive/definitive yet (should be for the actual release), but this might be helpful:

https://github.com/nim-lang/Nim/blob/devel/changelog.md

I beat you by 39 seconds! Hah! :-)

Thanks to both. Just the forum announcement wasn't very helpful for people outside the community.

Oh, it's a very understandable request. And you are welcome!
