OpenVPN 3 Linux v13 (beta) The highlights of this release includes: * Feature: IPv6 and TCP protocol support in OpenVPN Data Channel Off-load (DCO) The DCO feature is currently a tech-preview feature. It is not targeted for production usage in its current shape. As this is still under heavy development, we currently only support the latest Fedora releases (Fedora 32 and newer) and Ubuntu 20.04. This currently requires Linux kernel 5.4 and newer. This release includes an updated ovpn-dco implementation which adds both TCP and IPv6 protocols to be used for the transport between client and server. If you are testing the DCO feature, also be sure you use the updated kmod-ovpn-dco package, or build the ovpn-dco module based on git commit 8f04ed862539f0. * Bugfix: Misleading argument count when options are missing arguments If an option requring a certain minimum amount of arguments was missing one or more arguments, for example using just --keepalive 30, the error would be: ERR_PROFILE_OPTION: option_error: option 'keepalive' must have at least 3 arguments This is incorrect. The correct number should be "2 arguments". This has been fixed in the OpenVPN 3 Core library which generated this error string. * Bugfix: Multi-factor authentication broke with v12_beta With the v12_beta release, web based authentication was added. This also added signalling support for the CR_TEXT authentication method which was not intended to be added. This resulted in many multi-factor authentication configurations to fail, in particular those connecting to OpenVPN Access Server. This has been corrected and openvpn3-linux does no longer signal CR_TEXT authentication method support.
