If a user upgrades from 19.11.4 to 20.02 or 20.05 based on hns3 network 
engine,

some features of hns3 will not be supported.  But in many cases 
customers prefer

to use the LTS version. We will recommend them to upgrade from 19.11.0 
to 19.11.4,

and will recommend that customers upgrade from 19.11.4 to 20.11.0 after the

release of 20.11.0.
