 - `SHOW_CATALOG_NB_TAGS`: Show number of tags per images on catalog page. This will produce + nb images requests, not recommended on large registries. (default: `false`).
 - `HISTORY_CUSTOM_LABELS`: Expose custom labels in history page, custom labels will be processed like maintainer label.
 - `USE_CONTROL_CACHE_HEADER`: Use `Control-Cache` header and set to `no-store, no-cache`. This will avoid some issues on multi-arch images (see [#260](https://github.com/Joxit/docker-registry-ui/issues/260)). This option requires registry configuration: `Access-Control-Allow-Headers` with `Cache-Control`. (default: `false`).
+- `THEME`: Chose your default theme, could be `dark`, `light` or `auto`. (default: `auto`). Since 2.4.0
+- `THEME_*`: See table in [Theme options](#theme-options) section. Since 2.4.0
