WordPress 5.0 RC3
The third release candidate for WordPress 5.0 is now available!
WordPress 5.0 will be released on December 6, 2018. This is a big release and needs your help—if you haven’t tried 5.0 yet, now is the time!
To test WordPress 5.0, you can use the WordPress Beta Tester plugin or you can download the release candidate here (zip).
For details about what to expect in WordPress 5.0, please see the first release candidate post.
This release candidate includes a fix for some scripts not loading on subdirectory installs (#45469), and user locale settings not being loaded in the block editor (#45465). Twenty Nineteen has also had a couple of minor tweaks.
Plugin and Theme Developers
Please test your plugins and themes against WordPress 5.0 and update the Tested up to version in the readme to 5.0. If you find compatibility problems, please be sure to post to the support forums so we can figure those out before the final release. An in-depth field guide to developer-focused changes is coming soon on the core development blog. In the meantime, you can review the developer notes for 5.0.
