But…
Update: Although new rules do indeed take effect two months after entering the Federal Register (i.e. today), those taking effect are only part of the full package. The Office of Management and Budget still has to sign off on the new rules, after which time there will be yet another delay as they are filed in the Register again before taking effect. So although the new rules have taken partial effect, they are are still awaiting final final approval.
Should you be worried? No. But you should stay angry.
