openconnect for anyconnect 4.x

[Maximilian Ortwein]

Dear Openconnect Team,

We are going to update our VPN-Servers from anyconnect 3.x to 4.x and 
would like to use openconnect as client on Linux and Android and maybe 
on Windows and Mac OS.

Is openconnect full compatible to anyconnect 4.x (we are going to use EC 
as default crypto)? Are there any known Problems with anyconnect 4.x?

Thank you for your response.
