[Kea-users] Multiple HA Configurations for one server

[Kraishak Mahtha]

Hi Darren,

Thanks for the confirmation, and also for sharing about the 2.3.4 release
key point,
Actually, when I saw the ISC website they say that the last stable version
is 2.2.0 so I am trying that in my data center for now, will check more
about the latest versions
