Where can I read kotlin release changelog?

Latest documented version is 1.3.50(august 2019)
Latest blog post version is 1.3.60 https://blog.jetbrains.com/kotlin/2019/11/kotlin-1-3-60-released/
Current release 1.3.61 with no release notes?

Which version should I use in production and where are release notes published if any?

For some reason the latest change log is not in the master branch. Not sure why. That said in my experience the change log is always available with each version release though, it just might take some searching to find it :wink:
