Yes, we’ve got it! After four betas, we’ve got RC1. What is release candidate? Well, it is almost the same as final version, but authors still may think that some of the testers can find some bugs inside. And probably we will!
I use WordPress 4.6 Release Candidate on my local server (and I used beta versions as well) and it works like a charm. My plugins and themes are also compatible, so… it’s about 2 am here… I go to sleep 🙂
