Viscosity For Mac & Windows: Version 1.9.3

Viscosity version 1.9.3 is now available for both macOS and Windows! This update includes a number of improvements, including refined support for Apple Silicon (M1) Macs, updated versions of both OpenVPN and OpenSSL, and a number of small bug fixes.

In particular, the Mac version has been updated to automatically detect common DNS misconfigurations and add a warning where appropriate. Problems such as unreachable servers, DNS servers routed through the wrong network interface, use of reserved DNS domains, conflicting DNS domains, and so forth, will be now identified and additional information added to the connection log. We anticipate this should greatly simplify troubleshooting DNS problems for users and administrators unfamiliar with macOS's DNS resolver system.

This version also updates OpenVPN to version 2.4.11 for both Mac and Windows. While this OpenVPN update addresses a potentially serious security issue, it only affects OpenVPN servers. Viscosity clients are unaffected.

Finally, this version also updates OpenSSL to version 1.1.1k for both platforms.

As a follow-up, we're pleased to report that Apple have confirmed that they've resolved the underlying problem (that could cause macOS updates to stall) that necessitated the previous 1.9.2 release of Viscosity with a workaround. This has been resolved in the recent macOS 11.3 update. While we'll leave Viscosity's workaround in place for the foreseeable future (out of an abundance of caution), updating to macOS 11.3 and onwards should always go smoothly, even if an older version of Viscosity is being used.
