In late summer 2021, we will be updating www.ecfr.gov to our newly designed eCFR. You can try out the new eCFR today at https://ecfr.federalregister.gov. We have made big changes to make the eCFR easier to use. Be sure to leave feedback using the Site Feedback button on the bottom right of each page!
