 - EJScreen 2.1 was released by EPA in October 2022. 
   It is called bg22 here.
   It uses ACS 2016-2020, which the Census Bureau released March 17, 2022
   (delayed from Dec 2021).

 - EJScreen 2.0 was released by EPA February 18, 2022. 
   It was called bg21 here.
   It used ACS 2015-2019, which the Census Bureau released December, 2020.
   (EJScreen 2.0 was called the "2021 version" and bg21 here
   because it would have been called the late 2021 version but was delayed).
