 ¹ GHC 9.2 contains a regression, rendering Clash error messages indecipherable. This change was reverted in 9.4.
 
 ² GHC 9.0.2 on Windows fails to compile `clash-cores`. We therefore don't run the Clash testsuite on CI for this combination.
 
-³ We use Stack to test on Windows/macOS. There is no resolver yet that uses GHC 9.6, so this remains untested.

 ## Cabal
 To use Cabal you need both Cabal and GHC installed on your system. We recommend using [ghcup](https://www.haskell.org/ghcup/). For more information, see [https://www.haskell.org/downloads/](https://www.haskell.org/downloads/).
