The upgrade to OpenVPN 2.4.0 makes changes that are incompatible with previous configurations. Take **special care** if you depend on VPN connectivity for **remote access**! Administrative interaction is required:

* Configuration is expected in sub directories now. Move your files from `/etc/openvpn/` to `/etc/openvpn/server/` or `/etc/openvpn/client/`.

* The plugin lookup path changed, remove extra `plugins/` from relative paths.

* The systemd unit `openvpn@.service` was replaced with `openvpn- client@.service` and `openvpn-server@.service`. Restart and reenable accordingly.

This does not affect the functionality of `networkmanager`, `connman` or `qopenvpn`.
