Just like the last Beta little to no concern or care for users that have been making Slashdot Slashdot for well over a decade. At least last Beta we had a chance to test and tell you it was broken (which was ignored), this time it was just dumped on the community broken.
I originally thought that the submit button was gone, but it showed up with a new color and stands out if you look far enough down the menu. That is the only thing positive I can see from the update. Interestingly, the "Preview" button on the "Submit" page actually looks like the old button so I can read it. (Please don't attempt to "fix" that with what you broke everywhere else)
