Before this commit, returning `false` in an ActiveRecord `before_` callback such as `before_create` would halt the callback chain. After this commit, the behavior is deprecated: will still work until the next release of Rails but will also display a deprecation warning. The preferred way to halt a callback chain is to explicitly `throw(:abort)`.
