Today we’ve released WordPress 4.9.4, the day following WordPress 4.9.3.

WordPress 4.9.4 is the first minor releaseMinor Release A set of releases or versions
having the same minor version number may be collectively referred to as .x , for
example version 5.2.x to refer to versions 5.2, 5.2.1, 5.2.3, and all other versions
in the 5.2 (five dot two) branch of that software. Minor Releases often make improvements
to existing features and functionality. of WordPress in over four years since WordPress
3.7 was released where not all users will be receiving an automatic update.

This isn’t by choice – a bugbug A bug is an error or unexpected result. Performance
improvements, code optimization, and are considered enhancements, not defects. After
feature freeze, only bugs are dealt with, with regressions (adverse changes from
the previous version) being the highest priority. went undetected during the 4.9.3
development cycle, and was only discovered hours after 4.9.3’s release. The bug 
causes a PHPPHP The web scripting language in which WordPress is primarily architected.
WordPress requires PHP 7.4 or higher Fatal error to be triggered when WordPress 
attempts to update itself.

Unfortunately this means that WordPress Administrators will need to proceed with
a WordPress update themselves, through the WordPress Administration panel (Just 
hit _Update Now_ under _Updates_), using WP-CLIWP-CLI WP-CLI is the Command Line
Interface for WordPress, used to do administrative and development tasks in a programmatic
way. The project page is [http://wp-cli.org/](http://wp-cli.org/) [https://make.wordpress.org/cli/](https://make.wordpress.org/cli/),
or via FTPFTP FTP is an acronym for File Transfer Protocol which is a way of moving
computer files from one computer to another via the Internet. You can use software,
known as a FTP client, to upload files to a server for a WordPress website. [https://codex.wordpress.org/FTP_Clients](https://codex.wordpress.org/FTP_Clients).
Hosts who apply updates automatically on their customers behalf will also be able
to continue to update sites as normal.

**What Happened?** [#43103-core](https://core.trac.wordpress.org/ticket/43103) aimed
to reduce the number of APIAPI An API or Application Programming Interface is a 
software intermediary that allows programs to interact with each other and share
data in limited, clearly defined ways. calls which get made when the autoupdate 
cron task is run. Unfortunately due to human error, the final commit didn’t have
the intended effect, and instead triggers a fatal error as not all of the dependancies
of `find_core_auto_update()` are met. For whatever reason, the fatal error wasn’t
discovered before 4.9.3’s release – it was a few hours after release when discovered.

**Ways to update:**

 * **Through the WordPress Administration area:** Simply visit your WordPress Dashboard
   → Updates and click “Update Now.”
 * **With WP-CLI:** If you have command line access to WordPress, and WP-CLI installed,
   [`wp core update`](https://developer.wordpress.org/cli/commands/core/update/)
   will update your site just as quickly as before.
 * **Manually by FTP:** If you prefer, you can update by [Downloading the latest ZIP](https://wordpress.org/download/),
   and using FTP to upload it to your site. The only changed files expected are `
   wp-includes/update.php` & `wp-includes/version.php`.
 * **With PHP**: If you have command line access, you can also update WordPress 
   simply by running `wp_maybe_auto_update()` inside of WordPress, for example: `
   php -r 'include "wp-load.php"; wp_maybe_auto_update();'`. This is also how we
   suggest hosts who don’t have WP-CLI installed proceed with automated updates 
   for their customers.

As noted above, only two files changed in this release – `wp-includes/update.php`&`
wp-includes/version.php`.

**Are there any security implications?** WordPress 4.9.3 and 4.9.4 do not include
any security fixes, however, in order for WordPress to receive future security updates
automatically sites will first need to be updated to 4.9.4.

**What we’re doing to prevent this happening again** We’ll be making a follow up
post after we’ve been able to determine how to ensure that this never happens again.
We don’t like bugs in WordPress any more than you do, and we’ll be taking steps 
to both increase automated coverage of our updates and improve tools to aid in the
detection of similar bugs before they become an issue in the future.
