ESM importmap and Marginalia

Hi, Wojtek here introducing you to upcoming Rails 7 goodies.
Modern web apps without JavaScript bundling or transpiling are now possible to build in Rails. Exciting new direction of frontend tooling, that most likely Rails 7.0 will aim. Introduced by DHH in this post.
Configurable tags can be automatically added to all SQL queries generated by Active Record. By default the application, controller and action details are added to the query tags, like this:
SELECT * FROM books /*application:MyApp;controller:books;action:index*/
Added support for multiple databases to rails db:setup and rails db:reset. Now those tasks can be run per database, like rails db:setup:primary.
Faster computers have meant that most apps won't see a big benefit from Spring on small to moderate size apps.
16 people contributed to Rails since last time. All the changes can be checked here. Until next week!
