Is this thing on?
Hey, everyone! Welcome to the latest edition of This Week in Rails - your one stop shop for all the goings-on in the Rails universe. My name is Todd and I’ll be your guide. Let’s get this party started!
We had 41 extraordinary people commit to Rails this past week, including 15 (!) newcomers. Wanna see your name on this list? Check out the list of issues.

==) for comparing
ActiveRecord::AttributeSet objects to each other.

script_name to each be included in routes for mounted Engines (the expected behavior is for one, not both to be used). This patch resolves that issue on master and 4-2-stable.
Fixes an issue where the
at: argument wouldn’t be cast properly for
assert_performed_with, causing tests to fail.
pk_and_sequence_for is not used by MySQL adapters and is being removed. There won’t be a deprecation cycle for this change, so note that your implementation may break if you’re overriding this method anywhere.
That’s all for This week in Rails. As always, there are many more changes than we have room to cover here, but feel free to check them out yourself.
Until next time!
