# WordPress 6.3 Release Day Process

[Preparation for WordPress 6.3](https://make.wordpress.org/core/handbook/about/release-cycle/releasing-major-versions/#pre-final-release)
final release is underway. This post shares the release process, including the timeline
and how you can help. The post will be kept up to date as the release process evolves.

## Release Timeline Overview

The current plan is as follows:

 * The [Dry Run](https://make.wordpress.org/core/handbook/about/release-cycle/releasing-major-versions/#dry-run)
   is scheduled on [2023-08-07 16:00 UTC](https://www.timeanddate.com/worldclock/fixedtime.html?iso=20230807T1600).
   ✅
 * The 24-hour code freeze started on [2023-08-07 19:07 UTC](https://www.timeanddate.com/worldclock/fixedtime.html?iso=20230807T1907).
   ✅
 * The[ release party](https://make.wordpress.org/core/handbook/about/release-cycle/releasing-major-versions/#release-day)
   is planned on [2023-08-08 19:00 UTC](https://www.timeanddate.com/worldclock/fixedtime.html?iso=20230808T1900)
   in the [#core Slack channel](https://wordpress.slack.com/archives/C02RQBWTW).

## Dry Run ✅

[The Dry Run](https://make.wordpress.org/core/handbook/about/release-cycle/releasing-major-versions/#dry-run)
is a key event as a final walk-through for the final release. As noted above, the
current plan is to start it on [2023-08-07 16:00](https://www.timeanddate.com/worldclock/fixedtime.html?iso=20230807T1600).
You are invited to observe and/or participate. It’ll happen in the [#core Slack channel](https://wordpress.slack.com/archives/C02RQBWTW).

What happens during the dry run?

 * Review 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. reports to determine if any are

   Also see [alpha (beta)](https://make.wordpress.org/core/2023/08/01/wordpress-6-3-release-day-process/?output_format=md#alpha-beta).).
 * Checks and any necessary updates are made in the `src/wp-admin/includes/update-
   core.php` file.
 * Pre-release scripts are run to ensure test suites, coding standards, and other
   automated checks pass.

If the results are acceptable, the release goes into a 24-hour code freeze period.

## 24-Hour Code Freeze ✅

After the dry run and before the release party starts, a mandatory 24-hour code 
freeze goes into effect.

What does this mean? No source code for 6.3.0 (i.e., in the 6.3 branchbranch A directory
in Subversion. WordPress uses branches to store the latest development code for 
each major release (3.9, 4.0, etc.). Branches are then updated with code for any
minor releases of that branch. Sometimes, a major version of WordPress and its minor
versions are collectively referred to as a "branch", such as "the 4.0 branch".) 
can be changed during these 24 hours.

What happens if a critical bug is reported during this period? The release squad
will meet with committers and maintainers to determine if the issue is a blockerblocker
A bug which is so severe that it blocks a release..

 * If yes, another RC release happens, and the release process restarts (meaning
   the dry run is repeated, and then the 24-hour code freeze clock restarts).
 * If not, then the bug is targeted for 6.3.1.

## The Release Party 📅

EDIT: The Release Party will finally start on [2023-08-08 19:00 UTC](https://www.timeanddate.com/worldclock/fixedtime.html?iso=20230808T1900)

~The release party on August 8th will start no sooner than 24h after the code freeze
starts, with the exact time to be determined accordingly. You are invited to observe
and/or participate. ~It’ll happen in the [#core Slack channel](https://wordpress.slack.com/archives/C02RQBWTW).

The release party walks through the steps in the [Major Version Release process](https://make.wordpress.org/core/handbook/about/release-cycle/releasing-major-versions/#release-day)
for anyone who wants to follow along.

Please note releasing a major version requires more time than releasing a betaBeta
A pre-release of software that is given out to a large group of users to trial under
real conditions. Beta versions have gone through alpha testing in-house and are 
generally fairly close in look, feel and function to the final product; however,
design changes often occur as part of the process. or release candidate. There are
more steps in the process. If any last-minute issues need addressing, more time 
will be needed.

## How You Can Help

A key part of the release process is checking that the ZIP packages work on all 
the available server configurations. If you have some of the less commonly used 
servers available for testing (IIS, in particular), that would be super helpful.
Servers running older versions of PHPPHP The web scripting language in which WordPress
is primarily architected. WordPress requires PHP 7.4 or higher and MySQLMySQL MySQL
is a relational database management system. A database is a structured collection
of data where content, configuration and other options are stored. [https://www.mysql.com](https://www.mysql.com/)
will also need testing.

You can start this early by running the [WordPress 6.3 RC3 packages](https://wordpress.org/download/releases/#betas),
which are built using the same method as the final packages.

During the release party, options will be provided on how to help test the release
package.

## Tips on What to Test

In particular, testing the following types of installs and updates would be much
appreciated:

 * Does a new WordPress install work correctly? This includes running through the
   manual install process, as well as 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 one-click installers.
 * Test upgrading from 4.0.38, 4.9.22, 5.8.6, 5.9.5, 6.0.3, 6.1.3, 6.2.2, and 6.3
   RC3, as well as any other versions possible.
 * Remove the `wp-config.php` file and test a fresh install.
 * Test single site and multisitemultisite Used to describe a WordPress installation
   with a network of multiple blogs, grouped by sites. This installation type has
   shared users tables, and creates separate database tables for each blog (wp_posts
   becomes wp_0_posts). See also **network**, **blog**, **site**/networknetwork (
   versus site, blog) (both subdirectory and subdomain) installations.
 * Does it upgrade correctly? Are the [files listed in `$_old_files`](https://core.trac.wordpress.org/browser/branches/5.9/src/wp-admin/includes/update-core.php#L21)
   removed when you upgrade?
 * Does multisite upgrade properly?

Testing the following user flows on both desktop and mobile would be great to validate
each function as expected:

 * Publish a post, including a variety of different blocks.
 * Comment on the post.
 * Install a new pluginPlugin A plugin is a piece of software containing a group
   of functions that can be added to a WordPress website. They can extend functionality
   or add new features to your WordPress websites. WordPress plugins are written
   in the PHP programming language and integrate seamlessly with WordPress. These
   can be free in the WordPress.org Plugin Directory [https://wordpress.org/plugins/](https://wordpress.org/plugins/)
   or can be cost-based plugin from a third-party./theme, or upgrade an existing
   one.
 * Change the site language.
 * If you’re a plugin developer, or if there are complex plugins you depend upon,
   test that they’re working correctly.
