Inquiry about ACS and 2020 census tract boundaries

I'm passing these questions on (that I didn't know the answers too offhand) for a friend at USC...

  • Does anyone know when the American Community Survey (ACS) data will start to be released with the new 2020 tracts? Perhaps when the 2020 5-year estimates are released in December?
  • Will we need to rely on crosswalks to convert all of our old ACS data (i.e. they won’t be re-releasing previous years of data with new boundaries)?

Thanks for any help!
