We will discontinue support for Sauce Connect versions 4.4.11 and below on Feb 28th, 2019. This change impacts customers using old, standalone Sauce Connect binaries as well customers using old Sauce Connect binary prepackaged with OnDemand Jenkins Plugin.

Update Process

  • If you use an old, standalone Sauce Connect binary (version 4.4.11 or below) then please upgrade to Sauce Connect 4.5.1 or above. Download the new Sauce Connect version from the following link. Test the new version in a development or staging environment by running some manual and automated tests. If you don’t notice any issues then please upgrade your production environment to the new version.

  • If you use an old Sauce Connect binary prepackaged with the Sauce OnDemand Jenkins plugin (versions 1.177 and below) then please use Jenkins system configuration to update to the latest OnDemand Jenkins plugin (version 1.178).


We have made this decision for the following reasons:

  • Keep up with the security best practices and drop Sauce Connect server support for vulnerable protocols like TLS 1.0 and 1.1.

  • Many of the Sauce Connect versions 4.4.11 and below were released more than a year ago and have critical bugs related to functionality and performance.

Customers are strongly encouraged to upgrade to the latest stable release 4.5.1. The latest version has been in production without any known major issues.

Best Practice

We regularly ship new features and improvements with Sauce Connect client releases. We recommend customers to use a new version Sauce Connect released in the last 3-months.

Please contact support@saucelabs.com if you have any questions or need additional information.
