0.23.4 - 2026-05-17

Added

• writeTOMLViaCraneUtils: write toml file in the Nix store using a TOML to
  JSON conversion implemented by a crane utility tool. Useful for flattening
  dependency chains and avoid dragging in remarshal and all of its
  dependencies.
• writeTOMLViaRemarshal: the previous implementation of writeTOML, now
  explicitly separated for backwards compatibility.

Changed

• writeTOML now, by default, refers to writeTOMLViaCraneUtils to minimize
  dependency chains on non-Rust projects. Bringing back the old behavior (using
  remarshal) can be done via craneLibRemarshal = craneLib.overrideScope (final: prev: { writeTOML = final.writeTOMLViaRemarshal; });

Fixed

• The default dummy source for UEFI correctly builds for no_std environments.
• craneUtils is now uses writableTmpDirAsHomeHook to better control cargo's
  home directory placement, avoiding issues on non-sandboxed builds.
