WordPress 4.9 Release Candidate (RC) is now available to download for testing.
A release candidate means that the core team is almost done with WordPress 4.9. But, there are millions of users and thousands of themes and plugins, and the core team is fully aware of the possibility that something might have been missed. So, the core development team is requesting all the WordPress users to test the platform for any bugs and notify the authors, if they find any issue.
The core development team has made around 30 changes since the last release of Beta 4 last week. You can learn more about the new features in WordPress 4.9 by clicking here. You can also check out our previous blog posts on WordPress Beta 1, Beta 2, Beta 3, and Beta 4.
If you find any bug or issue, you can report them to the Alpha/Beta support forum. This will help the development team to ship WordPress 4.9, on Tuesday, November 14. If any known issues come up, you’ll be able to find them here.
Developers have been asked to test their plugins and themes against WordPress 4.9 and update their 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 the team can figure those out before the final release of WordPress 4.9. 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.
