      arguments:
        # test if its __palette_1 (dark) or __palette_2 (light)
        theme: |
          ^(JSON.parse(window.localStorage.getItem(__prefix('__palette'))).index == 1) ? 'dark' : 'light''

docs/extra/refresh_on_toggle_dark_light.js

var paletteSwitcher1 = document.getElementById("__palette_1");
var paletteSwitcher2 = document.getElementById("__palette_2");

paletteSwitcher1.addEventListener("change", function () {
  location.reload();
});

paletteSwitcher2.addEventListener("change", function () {
  location.reload();
});

It would be great if you could outline here (for a person who has notions of HTML/css/js) what had changed in the mkdocs-material internal API?

The internal API to store and retrieve local settings, including the currently selected theme/palette, changed a little bit - previously the browser’s localStorage was used directly (a bit like cookies, but only client-side) - now there’s some kind of wrapper around it, which also renames the key of the value depending on where it’s stored.

See the diff of src/assets/javascripts/components/palette/index.ts and src/partials/javascripts/base.html between pre- and post-8.0.0.

Thanks a lot!
