WordPress 4.9 Release Candidate

October 31st, 2017

The release candidate for WordPress 4.9 is now available.

RC means we think we’re done, but with millions of users and thousands of plugins and themes, it’s possible we’ve missed something. We hope to ship WordPress 4.9 on Tuesday, November 14, but we need your help to get there. If you haven’t tested 4.9 yet, now is the time!

To test WordPress 4.9, you can use the WordPress Beta Tester plugin or you can download the release candidate here (zip).

We’ve made almost 30 changes since releasing Beta 4 last week. For more details about what’s new in version 4.9, check out the Beta 1, Beta 2, Beta 3, and Beta 4 blog posts.

Developers, please test your plugins and themes against WordPress 4.9 and update your plugin’s Tested up to version in the readme to 4.9. If you find compatibility problems please be sure to post to the support forums so we can figure those out before the final release — we work hard to avoid breaking things. 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 4.9.

If you think you’ve found a bug, you can post to the Alpha/Beta area in the support forums. We’d love to hear from you! If you’re comfortable writing a reproducible bug report, file one on WordPress Trac, where you can also find a list of known bugs.

Thanks for your continued help testing out the latest versions of WordPress.
