We're very pleased to announce that version 1.7 of Viscosity is now available for both Mac and Windows! This is one of our biggest updates yet, with significant engineering changes for improved speed and performance, new features, and lots of small tweaks and fixes.
There are a number of enhancements to the user interface, including new ways to manage and import connections. Viscosity's main menu has been overhauled to offer more information at a glance and to make active connections more accessible. IP addresses, traffic totals, and traffic rates can now all be displayed alongside the connection status. The Details window has also been updated to display additional connection information, in particular DNS servers and encryption details for active connections.
Viscosity 1.7 adds support for OpenVPN 2.4, which offers new encryption functionality, improved dual-stack IP support, and many small enhancements. As well as OpenVPN 2.4.2, the OpenVPN 2.3 branch has been updated to version 2.3.16.
Viscosity has also seen many internal improvements on both Mac and Windows platforms to boost speed and performance. The Mac version has been re-implemented from the ground up to remove legacy code and adopt more moden APIs. This has a large and noticeable impact on Viscosity's performance, with everything from startup time to connection processing speed enhanced.
A new "Block IPv6 traffic while connected to IPv4-only connections" option has been added to prevent IPv6 traffic leaks when connecting to VPN connections that tunnel all IPv4 traffic only. The Windows version of Viscosity also now uses the Viscosity DNS System for Full DNS Mode (instead of just Split DNS mode) to prevent any potential DNS leaks due to the Windows DNS System changes in the Windows 10 Creators Update.
We're also pleased to introduce traffic obfuscation (obfsproxy) support in Viscosity. By setting up an obfsproxy server and enabling obfuscation in Viscosity you can avoid connectivity problems on networks that may attempt to block or limit VPN connections, such as some Wi-Fi hotspots or censorship prone areas.
Version 1.7 also contains a large assortment of other small improvements, including editor changes, connection management improvements, improved reconnection behaviour, small requested tweaks, and much more. Please refer to the release notes below for a complete list of changes.
