Hello everyone! This is Claudio with a recap of the main commits that made it into rails/rails this week. If you too want to contribute to Rails, this outstanding Active Record issue is a great place to start.
A work in progress to improve the documentation of Rails with a nicer theme, better SEO and faster generation time. Can you spot the difference between the current and the future version?
Two weeks ago, Active Storage made it into rails/rails. This week its documentation has been improved to make it ready to ship with Rails 5.2.

If you want to learn how to use benchmarks to prove that a commit can improve the performance of Rails, this is a great example.
