 -   Filter images and tags with a search bar. You can select the search bar with the shortcut `CRTL` + `F` or `F3`. When the search bar is already focused, the shortcut will fallback to the default behavior (see [#213](/~https://github.com/Joxit/docker-registry-ui/issues/213)).
 -   **Forward** custom header to your backend registry via environment variable and file via `NGINX_PROXY_PASS_HEADER_*` (see [#206](/~https://github.com/Joxit/docker-registry-ui/pull/206)).
 -   Run the container with user nginx instead of root via `--user nginx` and listend on custom port via `NGINX_LISTEN_PORT` (see [#224](/~https://github.com/Joxit/docker-registry-ui/issues/224)).
+-   Show number of tags per images on catalog page. This will produce + nb images requests, not recommended on large registries via `SHOW_CATALOG_NB_TAGS` (default: `false`) (see [#161](/~https://github.com/Joxit/docker-registry-ui/issues/161) and [#239](/~https://github.com/Joxit/docker-registry-ui/pull/239)).
+-   Expose custom labels in history page, custom labels will be processed like maintainer label via `HISTORY_CUSTOM_LABELS` (see [#160](/~https://github.com/Joxit/docker-registry-ui/issues/160) and [#240](/~https://github.com/Joxit/docker-registry-ui/pull/240)).

     - When you delete an image with the UI, only the reference is deleted and not the content. To remove dangling images, you need to run the garbage collector of the registry with the command `registry garbage-collect config.yml` or `docker exec registry registry garbage-collect config.yml`. (see [#77](/~https://github.com/Joxit/docker-registry-ui/issues/77) [#147](/~https://github.com/Joxit/docker-registry-ui/issues/147))
 -   Why when I delete one tag, all tags with the same SHA are deleted ?
     - This a docker registry API limitation, there is only one way to [delete images with tag](https://docs.docker.com/registry/spec/api/#deleting-an-image), it's by its `name` and its `manifest` (it's a sha of the content). So when you delete a tag, this will delete all tags of this image with the same SHA/manifest.
+-   Can I run the container with an unprivileged user ?
+    - Yes you can run the container with the `nginx` user, (see [#224](/~https://github.com/Joxit/docker-registry-ui/issues/224)).
