- 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.
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.
