You can now set config.active_record.primary_key = :uuid to have the Rails generator add id: :uuid whenever your migrations create a table.

Delegating a method to :block will now raise an exception. This is to prevent Rails from trying to invoke a block, rather than delegating the method. Same for :args and :arg.

A great PR to learn how to contribute to Rails by improving performance while providing repeatable benchmarks to validate the results.

1.year used to return the number of seconds in a year as a Float. This was confusing and inconsistent with similar methods. Now it returns a Fixnum (in case you are wondering, it’s 31,557,600).

number_to_human(999_999_999) will now print "1 Billion" rather than "1000 Million".

Rather than a generic ActionController::BadRequest, requesting a route with wrongly encoded parameters will now return a more helpful message.

After this fix, calling helper in the Rails console, editing the source code of a helper and then typing reload! will work as expected.

Validating the numericality of BigDecimal was subject to errors due to the value being parsed to a Float. Everything works now!

When editing the API documentation, use an extra comma to keep the comments consistent, uniform, and beautiful.
