It looks like a new syntax for declaring enums in your models has been introduced. Instead of passing the name and values as a key/value pair, it can now be passed as two separate arguments instead. Not a big change in itself but what this enables is in my opinion a more intuitive way to pass additional options.

Rails 7 adds Enumerable#maximum and Enumerable#minimum methods to easily calculate the maximum or minimum from extracted elements. These methods have existed in ActiveRecord for some time now and is useful when you have a collection of records.
