Which browser versions are supported in SauceLabs?
SauceLabs supports many major versions, as well as dev and beta versions of most widely used browsers. We do not support specific minor versions, and you cannot select specific minor version to use for your tests.
Why doesn't Sauce Labs provide all minor versions?
Our service is designed for speedy and efficient provisioning of desired platform-browser combinations for your tests. It is impractical for us to maintain virtual machine images with every minor browser version, and hosting many different browser versions would result in far too many idle, unused VMs. The only way Sauce Labs can spin up the test VMs quickly is by using a finite number of images. Downloading and installing user specified versions of browsers with each test is not a feasible solution either. Doing so would dramatically slow down tests across our whole cloud.
Are the browser versions offered by SauceLabs relevant?
To satisfy needs of our customers, we put active research into what versions are used the most in the world and support those. Obviously, usage changes and new versions come out. Sauce Labs adapts to these new usage patterns and adds support for new versions based on that. Most customers are happy with this because the browser versions we offer reflect what their own customers are most likely to use day-to-day.
In the end, no one can control which browser versions users will use to access your website, and therefore it is not crucial that tests are run on a specific minor version of a browser.
