New release

[seblyng]

Hi :)

Just wondering if it's possible to create a new release soon? I had a PR a while ago adding better support for document colors, and it would be nice if that could be in a release. I see the last release is over 3 months ago

Thanks!

I think maintainers have hear your request and released 3.15.0 😂
