I’m unsure where you heard this news, but Microsoft has not announced any plans for Windows 11 that I am aware of. In fact, last I heard, future builds of Windows will be upgrades of 10 for the foreseeable future.
We’ll continue working with Microsoft with any future builds of Windows anyway, for as long as it’s feasible. Obviously I can’t make 100% promises for future content - there’s always the possibility that something happens which makes it impossible or infeasible to support a certain operating system, but at this time we have no plans to terminate support for the latest stable builds of Windows 10.
(Note: this does not mean that we support the latest Insider Preview build - these are considered Beta and any issues with them should be reported to Microsoft and/or at our Bug Report forums.)
