The next major version of WordPress is knocking at the door. WordPress 4.6 is in full swing development mode, and the core development team have set the target release for August 16, 2016.
The final planned beta version of WordPress 4.6 Beta 4 is available now.
As it is the beta version, no more new features will be added before the final release of WordPress 4.6. Even some of the existing features in beta may not come with the final release. We’ll only know that after the final version has released.
This software is still in development, that is why the WordPress team recommended you not to try it on a production site, but you can consider this beta version to setting up a test site just to play with the new version.
WordPress team also recommended trying the WordPress Beta Tester Plugin while test WordPress 4.6.
The new version will be more stable and bug fixed. It is coming with better user management along with better post management and better security.
