[Openvpn-devel] [PATCH 7/7] add message about changing default values

[Antonio Q. <a...@un...>]

With OpenVPN 2.6 there are a number of default settings that are changing
to more modern and safer values.

Some users may not be aware of that and may experience problematic
behaviours, especially when connecting to older peers.

Add warning at startup to notify users about the change.
