 - **Latest tag/version is automatically built weekly**, so you should often update your images regardless if you're already using the latest Nextcloud version.
 - **Build production images without cache** (use `docker build --no-cache` for instance) if you want to build your images manually. Latest dependencies will hence be used instead of outdated ones due to a cached layer.

You can also disable the security module altogether by changing the `PHP_HARDENING` environment variable to `false` before recreating the container.
