[edk2] Shell 2.0 and 2.1

[Daniel Samuelraj]

Hi,

I assume that Shell 2.0 apps are expected to run fine in Shell 2.1. Can you
please confirm?



Should shell 2.1 app be using new toolkit (e.g., UDK2014 or newer?) when
app want to make use of the content added in Shell 2.1?



Will there be any backward or forward compatibility issue? That is end user
running Shell 2.0 app in shell 2.1; similarly running Shell 2.1 app in
Shell 2.0?



Appreciate the response!



Thanks,

Daniel
