- Improve handling of tarballs that don't consist of a single top-level directory [#11195](https://github.com/NixOS/nix/pull/11195)

  In previous Nix releases, the tarball fetcher (used by `builtins.fetchTarball`) erroneously merged top-level directories into a single directory, and silently discarded top-level files that are not directories. This is no longer the case. The new behaviour is that *only* if the tarball consists of a single directory, the top-level path component of the files in the tarball is removed (similar to `tar`'s `--strip-components=1`).

- Setting to warn about large paths [#10778](https://github.com/NixOS/nix/pull/10778)

  Nix can now warn when evaluation of a Nix expression causes a large
  path to be copied to the Nix store. The threshold for this warning can
  be configured using the `warn-large-path-threshold` setting,
  e.g. `--warn-large-path-threshold 100M`.
