## 5.0.0 (Unreleased) ### Breaking Changes - `PaperTrail.enabled=` now affects all threads - [#556](https://github.com/airblade/paper_trail/pull/556) / [#301](https://github.com/airblade/paper_trail/issues/301) - If you are tracking who is responsible for changes with `whodunnit`, be aware that PaperTrail no longer adds the `set_paper_trail_whodunnit` before_filter for you. Please add this before_filter to your ApplicationController to continue recording whodunnit. See the readme for an example. - [#683](https://github.com/airblade/paper_trail/pull/683) / [#682](https://github.com/airblade/paper_trail/issues/682) - Destroy callback default changed to :before to accommodate ActiveRecord 5 option `belongs_to_required_by_default` and new Rails 5 default. ### Added - [#689](https://github.com/airblade/paper_trail/pull/689) - Rails 5 compatibility ### Fixed - [#701](https://github.com/airblade/paper_trail/pull/701) / [#699](https://github.com/airblade/paper_trail/issues/699) - Cleaning old versions explicitly preserves the most recent versions instead of relying on database result ordering. ## 4.1.0 (2016-01-30) ### Breaking Changes - None ### Added - A way to control the order of AR callbacks. [#614](https://github.com/airblade/paper_trail/pull/614) - Added `unversioned_attributes` option to `reify`.

Thanks to everyone who helped test the two betas and two release candidates. ### Breaking Changes - Using a Rails initializer to reopen PaperTrail::Version or otherwise extend PaperTrail is no longer recommended. An alternative is described in the readme. See https://github.com/airblade/paper_trail/pull/557 and https://github.com/airblade/paper_trail/pull/492. - If you depend on the `RSpec` or `Cucumber` helpers, you must [require them in your test helper](https://github.com/airblade/paper_trail#testing). - [#566](https://github.com/airblade/paper_trail/pull/566) - Removed deprecated methods `paper_trail_on` and `paper_trail_off`. Use `paper_trail_on!` and `paper_trail_off!` instead. - [#458](https://github.com/airblade/paper_trail/pull/458) - Version metadata (the `:meta` option) from AR attributes for `create` events will now save the current value instead of `nil`. - [#391](https://github.com/airblade/paper_trail/issues/391) - `object_changes` value should dump to `YAML` as a normal `Hash` instead of an `ActiveSupport::HashWithIndifferentAccess`. - [#375](https://github.com/airblade/paper_trail/pull/375) / [#374](https://github.com/airblade/paper_trail/issues/374) / [#354](https://github.com/airblade/paper_trail/issues/354) / [#131](https://github.com/airblade/paper_trail/issues/131) - Versions are now saved with an `after_` callback, instead of a `before_` callback. This ensures that the timestamp field for a version matches the corresponding timestamp in the model. - `3da1f104` - `PaperTrail.config` and `PaperTrail.configure` are now identical: both return the `PaperTrail::Config` instance and also yield it if a block is provided. ### Added - [#525](https://github.com/airblade/paper_trail/issues/525) / [#512](https://github.com/airblade/paper_trail/pull/512) - Support for virtual accessors and redefined setter and getter methods. - [#518](https://github.com/airblade/paper_trail/pull/518) - Support for querying against PostgreSQL's [`JSON` and `JSONB` column types](http://www.postgresql.org/docs/9.4/static/datatype-json.html) via `PaperTrail::VersionConcern#where_object` and `PaperTrail::VersionConcern#where_object_changes` - [#507](https://github.com/airblade/paper_trail/pull/507) - New option: `:save_changes` controls whether or not to save changes to the `object_changes` column (if it exists). - [#500](https://github.com/airblade/paper_trail/pull/500) - Support for passing an empty array to the `on` option (`on: []`) to disable all automatic versioning. - [#494](https://github.com/airblade/paper_trail/issues/494) - The install generator will warn the user if the migration they are attempting to generate already exists. - [#484](https://github.com/airblade/paper_trail/pull/484) - Support for [PostgreSQL's `JSONB` Type](http://www.postgresql.org/docs/9.4/static/datatype-json.html) for storing `object` and `object_changes`. - [#439](https://github.com/airblade/paper_trail/pull/439) / [#12](https://github.com/airblade/paper_trail/issues/12) - Support for versioning associations (has many, has one, etc.) one level deep. - [#420](https://github.com/airblade/paper_trail/issues/420) - Add `VersionConcern#where_object_changes` instance method; acts as a helper for querying against the `object_changes` column in versions table. - [#416](https://github.com/airblade/paper_trail/issues/416) - Added a `config` option for enabling/disabling utilization of `serialized_attributes` for `ActiveRecord`, necessary because `serialized_attributes` has been deprecated in `ActiveRecord` version `4.2` and will be removed in version `5.0` - [#399](https://github.com/airblade/paper_trail/pull/399) - Add `:dup` argument for options hash to `reify` which forces a new model instance. - [#394](https://github.com/airblade/paper_trail/pull/394) - Add RSpec matcher `have_a_version_with` for easier testing. - [#347](https://github.com/airblade/paper_trail/pull/347) - Autoload `ActiveRecord` models in via a `Rails::Engine` when the gem is used with `Rails`. ### Fixed - [#563](https://github.com/airblade/paper_trail/pull/563) - Fixed a bug in `touch_with_version` so that it will still create a version even when the `on` option is, e.g. `[:create]`. - [#541](https://github.com/airblade/paper_trail/pull/541) - `PaperTrail.config.enabled` should be Thread Safe - [#451](https://github.com/airblade/paper_trail/issues/451) - Fix `reify` method in context of model where the base class has a default scope, and the live instance is not scoped within that default scope. - [#440](https://github.com/airblade/paper_trail/pull/440) - `versions` association should clear/reload after a transaction rollback. - [#438](https://github.com/airblade/paper_trail/issues/438) - `ModelKlass.paper_trail_enabled_for_model?` should return `false` if `has_paper_trail` has not been declared on the class. - [#404](https://github.com/airblade/paper_trail/issues/404) / [#428](https://github.com/airblade/paper_trail/issues/428) - `model_instance.dup` does not need to be invoked when examining what the instance looked like before changes were persisted, which avoids issues if a 3rd party has overriden the `dup` behavior.
