WordPress 6.4 Beta 2

WordPress 6.4 Beta 2 is now available for testing!

This beta version of the WordPress software is under development. Please do not install, run, or test this version of WordPress on production or mission-critical websites. Instead, it is recommended you evaluate Beta 2 on a test server and site.

You can test WordPress 6.4 Beta 2 in four ways:

  1. Plugin: Install and activate the WordPress Beta Tester plugin on a WordPress install (select the “Bleeding edge” channel and “Beta/RC Only” stream).
  2. Direct download: Download the Beta 2 version (zip) and install it on a WordPress website.
  3. Command line: Use the following WP-CLI command:
    wp core update --version=6.4-beta2

The current target for the final release of WordPress 6.4 is November 7, 2023. Get an overview of the 6.4 release cycle, and check the Make WordPress Core blog for 6.4-related posts in the coming weeks for more information.

The WordPress 6.4 release is brought to you by an underrepresented gender release squad to increase participation and partnership with those who identify as gender-underrepresented in the WordPress open source project.

How to get involved with testing

Your help testing the WordPress 6.4 Beta 2 version is key to ensuring everything in the release is the best it can be. While testing the upgrade process is essential, trying out new features is equally important. This guide will walk you through testing features in WordPress 6.4.

The Font Library feature, currently available in Gutenberg 16.7, requires more testing and feedback to ensure it is ready for inclusion in the upcoming 6.4 release. Check out this guide for detailed test instructions.

If you encounter an issue, please report it to the Alpha/Beta area of the support forums or directly to WordPress Trac if you are comfortable writing a reproducible bug report. You can also check your issue against a list of known bugs.

Note on pattern management improvements in non-block themes

While WordPress 6.4 will bring several exciting pattern advancements, improvements to pattern management in non-block themes will eventually be addressed in WordPress 6.5. The Beta 1 announcement has been updated to reflect this change accordingly.

Not the first, nor last
A second space to reflect
Both new and not new
