On August 18th, 2015, WordPress **Version 4.3**, named after jazz musician Billie
Holiday, was released to the public. For more information on this enhancement and
bug-fix release, read the [WordPress Blog](https://wordpress.org/news/2015/08/billie/),
and see the [Changelog for 4.3](https://codex.wordpress.org/Changelog/4.3).

For **Version 4.3**, the database version (**db_version** in **wp_options**) changed
to 33055, and the [Trac](https://core.trac.wordpress.org/) revision was 33635.

## 󠀁[Highlights](https://wordpress.org/documentation/wordpress-version/version-4-3/?output_format=md#highlights)󠁿

 * **The Finer Points**
    - [Resetting Your Password](https://codex.wordpress.org/Resetting_Your_Password)
      received attention and 4.3 improves the way that passwords are chosen and 
      changed. You start out with a strong password by default and you are given
      the option to keep it or choose your own. A password strength meter is available
      as well as the option to hide your password from prying eyes. You will find
      the new password interface on the password reset screen and the WordPress 
      install screen. WordPress will no longer send passwords via email and the 
      password reset links will expire in 24 hours. Finally, e-mail notifications
      will be sent out in the event that an e-mail or password is changed.
    - Site owners can now manage their site’s favicon on desktop and mobile. Site
      Icons work out of the box, are theme independent, and do not require theme
      support.
    - Multisite Focused Changes
    - The main change to the [Editor](https://codex.wordpress.org/Writing_Posts)
      is that the content for both Visual and Text editors is prepared/escaped the
      same (we run the textarea content through the JavaScript `wpautop()` before
      initializing TinyMCE).
    - Comments are now turned off on pages and custom post types by default.
 * **For Developers**
    - Fast previewing changes to Menus in the Customizer
    - A new theme template has been added to the [Template Hierarchy](https://codex.wordpress.org/Template_Hierarchy).
      The `singular.php`template follows the rules of `is_singular` and is used 
      for a single post, regardless of post type. It comes in the hierarchy after`
      single.php`, `page.php`, and the variations of each. Themes that used the 
      same code for both of those files (or included one in the other) can now simplify
      down to the one template.
    - Changes to Customizer Panels and Sections
    - New Customizer Media Controls
    - The [Site Icon](https://make.wordpress.org/core/2015/07/27/site-icon/) API
      is fairly straightforward.
    - PHP7 is slated for release later this year. One of the changes is that PHP4
      style constructors are deprecated. In order to prepare WordPress to support
      PHP7, these constructors have been deprecated in WordPress core.
    - Old Distraction Free Writing code has been removed (the code has not been 
      used in the core since [4.1](https://codex.wordpress.org/Version_4.1)). Plugin
      authors have had two releases to update their code. If it is essential to 
      your plugin, the files in [4.2](https://codex.wordpress.org/Version_4.2) can
      still be reused and improved.
