 - GCC 9, 10, 11, and 12 have been removed, as they have reached end‐of‐life upstream and are no longer supported.
 
-- GHC 8.6 and its package set have been removed. It was only used to bootstrap GHC for powerpc64le, but this was probably broken anyway.
-
 - 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 9.0 and its package set have been removed.
+- GHC 8.6, 8.10, 9.0, 9.2, and their package sets have been removed.
+
+- Support for bootstrapping native GHC compilers on 32‐bit ARM and little‐endian 64‐bit PowerPC has been dropped.
+  The latter was probably broken anyway.
+  If there is interest in restoring support for these architectures, it should be possible to cross‐compile a bootstrap GHC binary.
 
 - `base16-builder` node package has been removed due to lack of upstream maintenance.
