I like to keep up to date with GSAP releases.
Unfortunately, the github releases don't have a changelog or release notes so subscribing there is not helpful. https://github.com/greensock/GSAP/releases
The blog posts have a lot of good info but they are not tagged properly as releases from the drop down filter.
I found that the newer blog posts use "release" tag instead of "releases".
So this RSS feed worked for me
https://greensock.com/blog/?rss=1&tags=release
but this one had the last update from version 2.1
https://greensock.com/blog/?rss=1&tags=releases
I just wanted to point it out and hopefully future blog posts could be tagged properly or GitHub tags will get release notes.
Thanks
