  - [#207](https://github.com/airblade/paper_trail/issues/207) - Versions for `'create'` events are now created with `create!` instead of

## 2.7.2

  - [#228](https://github.com/airblade/paper_trail/issues/228) - Refactored default `user_for_paper_trail` method implementation
  so that `current_user` only gets invoked if it is defined.

  reified properly depending on the way the serializer worked.

    Factored out `version_key` into it's own method to prevent `ConnectionNotEstablished` error from getting thrown in
    instances where `has_paper_trail` is declared on class prior to ActiveRecord establishing a connection.

  - [#160](https://github.com/airblade/paper_trail/pull/160) - Fixed failing tests and resolved out of date dependency issues.
  - [#157](https://github.com/airblade/paper_trail/pull/157) - Refactored `class_attribute` names on the `ClassMethods` module
    for names that are not obviously pertaining to PaperTrail to prevent method name collision.
