Attention is currently required from: flichtenheld, plaisthos. Hello plaisthos, flichtenheld, I'd like you to do a code review. Please visit http://gerrit.openvpn.net/c/openvpn/+/869?usp=email to review the following change. Change subject: PUSH_UPDATE message sender: enabling the server to send PUSH_UPDATE control messages ...................................................................... PUSH_UPDATE message sender: enabling the server to send PUSH_UPDATE control messages Using the management interface you can now target one or more clients (via broadcast, via cid, via common name, via address) and send a PUSH_UPDATE control message to update some options.
