- `nix-shell` shebang lines now support single-quoted arguments.

- `builtins.fetchTree` is now its own experimental feature, [`fetch-tree`](@docroot@/contributing/experimental-features.md#xp-fetch-tree).
As described in the documentation for that feature, this is because we anticipate polishing it and then stabilizing it before the rest of flakes.
This allows stabilising it independently of the rest of what is encompassed by [`flakes`](@docroot@/contributing/experimental-features.md#xp-fetch-tree).

- The interface for creating and updating lock files has been overhauled:

This built-in was previously guarded by the `flakes` experimental feature because of that overlap,
but since the plan is to work on stabilizing this first (due 2024 Q1), we are putting it underneath a separate feature.
Once we've made the changes we want to make, enabling just this feature will serve as a "release candidate" --- allowing users to try out the functionality we want to stabilize and not any other functionality we don't yet want to, in isolation.
