 We have been working on [moving the nixpkgs Haskell documentation back into the
-nixpkgs manual](https://github.com/NixOS/nixpkgs/issues/121403). Since this
-process has not been completed yet, you may find some topics missing here

 - GHC 8.6, 8.10, 9.0, 9.2, and their package sets have been removed.
 
+- The `haskellPackages.mkDerivation` builder now converts packages' cabal files to Unix line endings before `patchPhase`. This behavior can be disabled using `dontConvertCabalFileToUnix`.
+
 - `webkitgtk_4_0` has been removed because it depends on an unmaintained version of security-critical libsoup library (`libsoup_2`) and the support will be [dropped upstream soon](https://webkitgtk.org/2025/10/07/webkitgtk-soup2-deprecation.html).
 
 - Support for bootstrapping native GHC compilers on 32‐bit ARM and little‐endian 64‐bit PowerPC has been dropped.
