The release candidate for WordPress 4.8 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 4.8 on Thursday, June 8, but we need your help to get there. If you haven’t tested 4.8 yet, now is the time!
To test WordPress 4.8, you can use the WordPress Beta Tester plugin or you can download the release candidate here (zip).
We’ve made a handful of changes since releasing Beta 2 earlier this week. For more details about what’s new in version 4.8, check out the Beta 1 and Beta 2 blog posts.
Think you’ve found a bug? Please post to the Alpha/Beta support forum. If any known issues come up, you’ll be able to find them here.
Developers, please test your plugins and themes against WordPress 4.8 and update your plugin’s Tested up to version in the readme to 4.8. 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.
