With a number of reported problems on iOS 9.01 and 9.02, Apple is in beta with a 9.1 version that is supposed to fix issues and become the stable release. We have iOS 9.1 beta ready now, so you can start testing and be ready for the general release predicted for late October or November. Check out all our browser / OS combinations at our platform configurator. At Sauce we are constantly improving our service by making it easier to integrate with CI systems, upgrading our UI and, lately, improving reliability and speed. We've just finished part one of a project to speed up the generation of VMs so you can test even faster. Our Windows VMs are now faster than ever, so check 'em out.
