WordPress 5.7 Release Candidate
The first release candidate for WordPress 5.7 is now available! 
Please join us in celebrating this very important milestone in the community’s progress towards the final release!
“Release Candidate” means that the new version is ready for release, but with millions of users and thousands of plugins and themes, it’s possible something was missed. WordPress 5.7 is slated for release on March 9, 2021, but your help is needed to get there—if you haven’t tried 5.7 yet, now is the time!

- Try the WordPress Beta Tester plugin (choose the “Bleeding edge” channel and Beta/RC Only” stream options)
- Or download the release candidate here (zip).
Thank you to all of the contributors who tested the Beta releases and gave feedback. Testing for bugs is a critical part of polishing every release and a great way to contribute to WordPress.
