Description of the feature request
Please upgrade the vs4mac beta stack to macOS 11 (Big Sur), Xcode 12.5, and the latest vs4mac.
The current vs4mac beta stack is macOS 10.15.7 (Catalina), Xcode 12.4, and outdated vs4mac (February).
Use case / for what or how I would use it
Build Xamarin.Android and Xamarin.iOS apps that use newer APIs and/or rely on bug fixes in the latest SDKs.
We would also like to have the stack updated. It seems like the newer stack address the issue we are facing: https://forums.swift.org/t/swift-package-binary-framework-issue/41922/9

Thanks for the #feature-request! We’ll keep an eye on the votes 
The vs4mac stack is nearly four months old.
Viable CI requires updates at least once per month.
Effectively, Bitrise has dropped support for Xamarin.
I discovered Bitrise while looking for an alternative to App Center. It seems I need to keep looking.
Thanks anyhow.
