WordPress has released WordPress 4.6 RC2. WordPress has made more than 30 changes since the release of first candidate. They are almost done with the 4.6 but since there are thousands of plugins and themes, there are still some possibilities that they missed something. WordPress is hopeful to ship WordPress 4.6 on August 16. But they can do this only with the help of its users.
Anyone can test the 4.6 as of now. One can use the WordPress Beta Tester plugin or direct download the release candidate from WordPress website.
