# Change Log #
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](http://keepachangelog.com/).

## [1.5.2](https://github.com/thebrandonallen/edit-author-slug/tree/1.5.1) - 2017-06-21 ##
### Fixed
* Fixed a regression where those using the default author based couldn't remove front unless they were also using role-based author bases. [GH-12]

## [1.5.1](https://github.com/thebrandonallen/edit-author-slug/tree/1.5.1) - 2017-06-02 ##
### Fixed
* Fixed a PHP notice when manually updating a user profile.

## [1.5.0](https://github.com/thebrandonallen/edit-author-slug/tree/1.5.0) - 2017-05-30 ##
### Added
* Added `CHANGELOG.md` file.
* Introduce `ba_eas_nicename_exists()` to check if a nicename exists.
* Added `LICENSE` file.
* Added `BA_Edit_Author_Slug::VERSION` & `BA_Edit_Author_Slug::DB_VERSION` class constants.

### Changed
* The plugin bootstrap was refactored, and BA_Edit_Author_Slug was moved into `includes/classes/class-ba-edit-author-slug.php`.
* Deprecated functions were moved into `includes/deprecated.php`.
* `ba_eas_can_edit_author_slug()` no longer checks `is_super_admin()`.
* `ba_eas_remove_front()` now checks `ba_eas_has_front()` on top of the `BA_Edit_Author_Slug::remove_front`.
* The `BA_Edit_Author_Slug` class is no longer declared `final`.
* Translations are only loaded from the WP languages folder (ie - wp-content/languages/plugins).
* Bumped minimum required WordPress version to 4.4.

### Deprecated
* Deprecated the `BA_Edit_Author_Slug::version` & `BA_Edit_Author_Slug::db_version` properties.
* Deprecated `ba_eas_get_wp_roles()`. Use `wp_roles()` instead. [GH-9]
* Deprecated `ba_eas_update_nicename_cache()`. Use `wp_cache_delete( $old_nicename, 'userslugs' )` instead. [GH-10]

### Fixed
* Refactored bulk upgrading again. The original fix made things better, but not as good as it could be. This new refactoring drastically improves performance and memory usage.
* Lots of minor optimizations...
