We are very excited to announce support for IPSec VPN on Sauce Labs virtual platforms. IPSec VPN is an industry standard technology to connect two private clouds securely over the Internet. An IPSec VPN tunnel between Sauce Labs and your private network allows Sauce virtual machines to access application servers hosted in your private network. 
IPSec VPN is an alternative to Sauce Connect. Both solutions provide similar functionality and security. The below table summarizes some of the differences.

Note: Sauce customers with existing VPN connections to Sauce real device or virtual platforms are not impacted by this new feature and can continue using the existing solutions.


Happy testing,

Our product just keeps getting Saucier! Occasionally mobile applications crash during a test and it is hard to identify the root cause of the problem. However, users can now access crash logs generated while testing an iOS application on Sauce iOS simulators. Crash logs contain valuable information like memory usage, call stacks of all the threads at the time of failure and help you debug crashes. Please refer to Apple's documentation on Crash Reports for more information.

Crash logs for mobile applications are supported on all iOS versions supported on Sauce simulators. Crash logs for a test can be accessed from Logs tab on Sauce Labs Test Details page.

In our continuing efforts to provide the best performing, most up-to-date platform for our users, Sauce Labs will discontinue support for Appium versions 1.6.2 and below on emulators and simulators on December 5th. We made this decision due to reduced market share of these versions, along with diminished usage by our customers. After December 5th, we will continue to support Appium versions 1.6.3 and above. 

We strongly recommend you to test your automation scripts with the highest compatible Appium version on Sauce as soon as possible so that you are not impacted by this change on December 5th. Note that newer Appium versions are backward compatible and are required to test on the latest iOS and Android versions. 


OSHighest Compatible Appium Version
iOS 9.31.7.1
iOS 10.0 - 10.21.8.0
iOS 10.3 and above1.9.1
Android all versions1.9.1


After you have validated that your Appium test scripts work as expected we recommend you to discontinue using appiumVersion capability in your test scripts. This allows Sauce to pick the most stable, recent version for your test configuration and allows you to stay up to date with newer Appium versions. 

Please refer to Platform Configurator for the most up-to-date list of supported Appium versions and mobile platforms on emulators and simulators.

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

Happy Testing,
Sauce Emulators and Simulators Team

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.
