 - GCC 9, 10, 11, and 12 have been removed, as they have reached end‐of‐life upstream and are no longer supported.
 
+- LLVM 12, 13, 14, 15, 16, and 17 have been removed, as they have reached end‐of‐life upstream and are no longer supported.

 - GHCJS 8.10, exposed via `haskell.compiler.ghcjs` and `haskell.compiler.ghcjs810`, has been removed. Downstream users should migrate their projects to the new JavaScript backend of GHC proper which can be used via `pkgsCross.ghcjs` from Nixpkgs. Haskell packaging code, like `haskellPackages.mkDerivation`, `ghcWithPackages` and `hoogleWithPackages`, also no longer supports GHCJS.
 
 - GHC 8.6, 8.10, 9.0, 9.2, and their package sets have been removed.
