WordPress 5.7 Beta 3
WordPress 5.7 Beta 3 is now available for testing! 
This software is still in development, so it’s not recommended to run this version on a production site. Consider setting up a test site to play with it.
You can test the WordPress 5.7 Beta 3 in two ways:
- Install/activate the WordPress Beta Tester plugin (select the
Bleeding edgechannel and theBeta/RC Onlystream) - Direct download the beta version here (zip).
The current target for final release is March 9, 2021. That’s just three weeks away, so your help is vital to making sure that the final release is as good as it can be.
