Ethernet Shield V2.0 Library not working with Uno

Hi, I’m trying out your Ethernet Shield V2.0 Library because I was hoping it would properly support multiple connections (official library only supports 1 connection) but I can’t get my Uno and regular ethernet shield to work with your new library. I tried to use the webserver example that comes with your new library but it does not initialize the w5100. Does your new library only work with the w5200 chip?
