Version 1.7.5 of Viscosity has been released for both Mac and Windows! This release includes a number of small improvements and bug fixes, and updates OpenVPN to versions 2.4.4 and 2.3.18. The OpenVPN updates address a potential security issue related to an old data channel key negotiation method, and users are encouraged to update.

This update also changes the name of Viscosity's TAP network interfaces on macOS from "tap" (e.g. "tap0") to "vtap". This is designed to prevent clashes with other VPN clients installed on the same system that are loading their own version of the TAP driver. We've received reports of some poorly managed clients that were conflicting with Viscosity's TAP support, which this change will resolve. Users with advanced custom scripts or actions may need to update the network interface name accordingly, however no changes are otherwise needed.
