+* Add Mongoid::History.disable and Mongoid::History.enabled? methods for global tracking disablement - [@johnnyshields](https://github.com/johnnyshields)
+* Add `:changes_method` that optionally overrides which method to call to collect changes - [@joelnordel](https://github.com/joelnordell).
+* [API Change] The `:destroy` action now stores trackers in the format `original=value, modified=nil` (previously it was the reverse) - [@johnnyshields](https://github.com/johnnyshields)
+* Support for polymorphic embedded classes - [@tstepp](https://github.com/tstepp)
+* Support for Mongoid field aliases, e.g. `field :n, as: :name` - [@johnnyshields](https://github.com/johnnyshields)

+* Add class-level `#tracked_field?` and `#tracked_fields` methods; refactor logic to determine whether a field is tracked - [@johnnyshields](https://github.com/johnnyshields)

+* Tests: Added spec for nested embedded documents - [@matekb](https://github.com/matekb)
+* Tests: Test run time cut in half (~2.5s versus ~5s) by using `#let` helper and removing class initialization before each test - [@johnnyshields](https://github.com/johnnyshields)
