* `Object#try` will now return nil instead of raise a NoMethodError if the receiving object does not implement the method, but you can still get the old behavior by using the new `Object#try!`.
+* `String#to_date` now raises `Argument Error: invalid date` instead of `NoMethodError: undefined method 'div' for nil:NilClass`
+ when given an invalid date. It is now the same as `Date.parse`, and it accepts more invalid dates than 3.x, such as:
+
+ ```
+ # ActiveSupport 3.x
+ "asdf".to_date # => NoMethodError: undefined method `div' for nil:NilClass
+ "333".to_date # => NoMethodError: undefined method `div' for nil:NilClass
+
+ # ActiveSupport 4
+ "asdf".to_date # => ArgumentError: invalid date
+ "333".to_date # => Fri, 29 Nov 2013
+ ```
+
### Deprecations
* Deprecate `ActiveSupport::TestCase#pending` method, use `skip` from MiniTest instead.
