ovpnmain.cgi includes new directive '--ncp-disable' to disable for the first the cipher negotiation. script-security flag 'system' has been dropped cause of security concerns. Directive changes/explanations can be found in here https://community.openvpn.net/openvpn/wiki/Openvpn24ManPage .
Update script for OpenVPN CRL has been integrated since OpenVPN refactors the CRL handling since v.2.4.0 . Script checks the next update field from the CRL and preforms an update two days before it expires. Script is placed under fcron.daily for daily checks. Changes can be found in here https://github.com/OpenVPN/openvpn/commit/160504a2955c4478cd2c0323452929e070... .
update.sh for Core 118 includes needed server.conf changes but also an update of the CRL to prevent connection problems if systems have already an expired CRL. Server stop and start if active will be also executed.
