We maintain support over several versions of the OSs our products run on, this is to ensure your properties are available to as many of your users as possible. From time to time, we revise our list of supported OS versions to reflect the declining usage of those platforms and the increased effort of maintaining our product standards on older technology. Here's more on why we drop support for OS versions, and how we ensure our products work consistently with new versions. 

This article links to the currently supported operating systems for each of our products.

Note that for web browsers we support the 2 most recent major versions of the below-stated browsers, and the last 3 years of MacOS and Windows releases.
