# Release X.Y (202?-??-??) * The Nix cli now searches for a flake.nix up until the root of the current git repository or a filesystem boundary rather than just in the current directory * The TOML parser used by `builtins.fromTOML` has been replaced by [a more compliant one](https://github.com/ToruNiina/toml11). * Added `:st`/`:show-trace` commands to nix repl, which are used to set or toggle display of error traces. * New builtin function `builtins.zipAttrsWith` with same functionality as `lib.zipAttrsWith` from nixpkgs, but much more efficient. * New command `nix store copy-log` to copy build logs from one store to another. * The `commit-lockfile-summary` option can be set to a non-empty string to override the commit summary used when commiting an updated lockfile. This may be used in conjunction with the nixConfig attribute in `flake.nix` to better conform to repository conventions.
