Whew! Seems like a pretty clean one? Ran `rails app:upgrade` and stuff, and made some corrections to keyword arguments for `translate` calls. There might be more such problems elsewhere? But that's hard to search for, and we'll have to see.
Another pretty easy one! We have the `rails app:update` changes in here too.
rails app:update
We accepted some changes as-is, but for development.rb and production.rb we read the diff and manually edited them!
