WordPress 4.0 "Benny" Released With Editing & Interface Improvements

WordPress 4.0 is finally here, and it goes by the name of "Benny". As per usual, WordPress has named this major release after a famous Jazz artist. This time, it's Clarinetist, Benny Goodman. But that's not what we're really interested in here (Sorry, Jazz fans).
