USEBIO 1.1 was announced in January 2013 as a successor to USEBIO 1.0. The primary motivation for the upgrade was to allow the EBU to include teams games into its National Grading System, which was not possible using the USEBIO 1.0 format. There are other minor additions, and a number of clarifications to elements that were ambiguous in USEBIO 1.0.
The EBU implemented USEBIO 1.1 in April 2014.
