Rails 6.1 Released— The newest Rails train has just pulled into the station! If your app needs the flexibility of per-database connection switching or horizontal sharding, this is a compelling update. We also get strict loading associations (stop N+1s in their tracks), delegated Active Record types (as a rather nicer alternative to STI), and performance improvements all round. Here’s a table showing if you’re ready to upgrade apps on various versions of Rails to the new version.

Ruby 3.0.0 Preview 2 Released— Are you ready for the final Ruby 3.0 release due on Christmas Day? If you want to get testing ASAP, this preview is what you need. Static typing (via RBS), ractors, TypeProf, one line pattern matching, MJIT, end-less method definitions, and Fiber#scheduler are all here. But bye bye to $SAFE.
