analog to the current automatic IPv4 setup.

- [`lib.options.mkPackageOptionMD`](https://nixos.org/manual/nixpkgs/unstable#function-library-lib.options.mkPackageOptionMD) is now obsolete; use the identical [`lib.options.mkPackageOption`](https://nixos.org/manual/nixpkgs/unstable#function-library-lib.options.mkPackageOption) instead.



- `nixosTests` now provide a working IPv6 setup for VLAN 1 by default.



- To facilitate dependency injection, the `imgui` package now builds a static archive using vcpkg' CMake rules.

  The derivation now installs "impl" headers selectively instead of by a wildcard.

  Use `imgui.src` if you just want to access the unpacked sources.
