Records

This release broke the old project record and is the first release ever to contain more than 300 bugfixes since the previous release. There were so many bugfixes landed that I decided to not even list my favorites in this blog post the way I have done in the past. Go read the full changelog, or watch the release video to see me talk about some of them.

Another project record broken in this release is the amount commits merged into the repository since the previous release: 501.
