5.2.0 is officially among us, a little bit ahead of RailsConf this year. If you can't wait until then to find out everything that this new release brings, do go read the original blog post that accompanied the release for all the details!

As always there were many more changes to the Rails codebase than we can cover here. But you can read all about them here! Until next week!
