 [^missing-stack-probes]: Stack probes support is missing on
   `aarch64-unknown-linux-gnu`, but it's planned to be implemented in the near
   future. The implementation is tracked on [issue #77071][77071].
 
+[^windows-support]: Only Windows 10 currently undergoes automated testing. Earlier versions of Windows rely on testing and support from the community.
