*   `attribute_changed?` now accepts parameters which check the old and new value of the attribute

    `model.name_changed?(from: "Pete", to: "Ringo")`

    *Tejas Dinkar*

*   Fix `has_secure_password` to honor bcrypt-ruby's cost attribute.

    *T.J. Schuck*

*   Updated the `ActiveModel::Dirty#changed_attributes` method to be indifferent between using
    symbols and strings as keys.

    *William Myers*

*   Added new API methods `reset_changes` and `changes_applied` to `ActiveModel::Dirty`
    that control changes state. Previsously you needed to update internal
    instance variables, but now API methods are available.

    *Bogdan Gusiev*

*   Fix `has_secure_password` not to trigger `password_confirmation` validations
    if no `password_confirmation` is set.

    *Vladimir Kiselev*

*   `inclusion` / `exclusion` validations with ranges will only use the faster
    `Range#cover` for numerical ranges, and the more accurate `Range#include?`
    for non-numerical ones.

    Fixes range validations like `:a..:f` that used to pass with values like `:be`.
    Fixes #10593.

    *Charles Bergeron*

*   Fix regression in `has_secure_password`. When a password is set, but a
    confirmation is an empty string, it would incorrectly save.

    *Steve Klabnik* and *Phillip Calvin*

*   Deprecate `Validator#setup`. This should be done manually now in the validator's constructor.

    *Nick Sutterer*
