## Rails 4.2.9 (June 26, 2017) ##

* Fixed bug in `DateAndTime::Compatibility#to_time` that caused it to
raise `RuntimeError: can't modify frozen Time` when called on any frozen `Time`.
Properly pass through the frozen `Time` or `ActiveSupport::TimeWithZone` object
when calling `#to_time`.

* Restore the return type of `DateTime#utc`

In Rails 5.0 the return type of `DateTime#utc` was changed to `Time` to be
consistent with the new `DateTime#localtime` method. When these changes were
backported in #27553 this inadvertently changed the return type in a patcn
release. Since `DateTime#localtime` was new in Rails 4.2.8 it's okay to
restore the return type of `DateTime#utc` but keep `DateTime#localtime` as
returning `Time` without breaking backwards compatibility.

* In Core Extensions, make `MarshalWithAutoloading#load` pass through the second, optional
argument for `Marshal#load( source [, proc] )`. This way we don't have to do
