Sauce Labs has updated its Sauce Connect feature with new security improvements and bug fixes over the past two years. The update includes features such as a built-in HTTP proxy server that securely connects testing environments to websites or mobile apps hosted locally or behind a corporate firewall. To ensure data safety, Sauce Labs offers several security measures, including support for Apple's App Transport Security protocol and validation of command line inputs. The company has also introduced new certificate validation methods and will discontinue support for older versions of Sauce Connect in 2021, strongly encouraging customers to upgrade to the latest stable release, version 4.6.2. To take advantage of these improvements, users should follow specific steps to update their outdated versions of Sauce Connect, including using the latest OnDemand Jenkins plugin version and making routine updates to the Sauce Connect client. The company plans to make several fundamental changes in its backend in 2021, which will necessitate support for all previous versions of the Sauce Connect client being discontinued.
