WordPress 6.3 Release Candidate 2

WordPress 6.3 RC2 is ready for download and testing.

This version of the WordPress software is under development. Please do not install, or run, or test this version on production or mission-critical websites. Instead, you should evaluate RC2 on a test server and site. 

While release candidates are considered ready for final release, additional testing and use by the community can only make it better.

WordPress 6.3 is scheduled for release on August 8, 2023 – just two weeks from today.

Test features in WordPress 6.3

Testing for issues is a critical part of developing any software, and it’s a meaningful way for anyone to contribute—whether you have experience or not. While testing the upgrade process is essential, trying out new features is too. 

• Encountered an issue? Please report it to the Alpha/Beta area in the support forums. If you are comfortable writing a reproducible bug report, you can file one on WordPress Trac. You can also check your issue against a list of known bugs.
• New to testing? This detailed guide is a great place to start if you’ve never tested a beta/RC release.

The monetary reward for reporting new, unreleased security vulnerabilities is doubled between the Beta 1 release and the final release candidate (RC). Please follow responsible disclosure practices as detailed in the project’s security practices and policies outlined on the HackerOne page and in the security white paper.
