As always, this release is loaded with fixes and improvements. It's currently set to ship Monday Dec 2 and so far no regressions have been found as far as I know. Final day to test the release candidate on your app, try it out ✌️
For the most part we highlight particular interesting commits in this newsletter, but there's usually other stuff we don't get to. Stuff that could help you make sense of Rails itself. This week I'd like to try to remedy that.
Here's all changes since last time. Visit the link and each time you see "Merge pull request #12345", click 'em. Feel free to see Files Changes and on particularly interesting files, you can try "View File" and read some surrounding code. This can be overwhelming so go easy. But that's pretty much a fine way to start reading Rails' actual code. It's all Ruby all the way down.
Now, some of the people in the list are on certain Rails teams. You'll likely interact with some of them if you submit a pull request. Here's who's in the current change list, but not the full teams.
