          During cross-compilation, tests are now executed if the test
          suite can be executed by the build platform. This is the case
          when doing “native” cross-compilation where the build and host
          platforms are largely the same, but the nixpkgs’ cross
          compilation infrastructure is used, e.g.
          <literal>pkgsStatic</literal> and <literal>pkgsLLVM</literal>.
          Another possibility is that the build platform is a superset
          of the host platform, e.g. when cross-compiling from
          <literal>x86_64-unknown-linux</literal> to
          <literal>i686-unknown-linux</literal>. The predicate gating
          test suite execution is the newly added
          <literal>canExecute</literal> predicate: You can e.g. check if
          <literal>stdenv.buildPlatform</literal> can execute binaries
          built for <literal>stdenv.hostPlatform</literal> (i.e.
          produced by <literal>stdenv.cc</literal>) by evaluating
          <literal>stdenv.buildPlatform.canExecute stdenv.hostPlatform</literal>.

          The <literal>nixpkgs.hostPlatform</literal> and

              defaults to the <literal>hostPlatform</literal>, for a
              non-cross build configuration. To cross compile, set

          The existing options
          <literal>nixpkgs.{system,localSystem,crossSystem}</literal>
          have not been formally deprecated, to allow for evaluation of
          the change and to allow for a transition period so that in
          time the ecosystem can switch without breaking compatibility
          with any supported NixOS release.

          You may have to unset the <literal>system</literal> parameter

          Alternatively, you can remove the

          <literal>pkgs.mullvad</literal>, allowing cross-platform usage
          of Mullvad. <literal>pkgs.mullvad</literal> only contains the
          Mullvad CLI tool, so users who rely on the Mullvad GUI will
          want to change it back to <literal>pkgs.mullvad-vpn</literal>,
          or add <literal>pkgs.mullvad-vpn</literal> to their

          Notes</link> provided by upstream before upgrading. Worth
          specifically noting is that the new Catalog Zones feature
          comes with a mandatory schema change for the gsql database
          backends, which has to be manually applied.
