   **x86-64 only** We have implemented the optional ability to pull in the dependencies to enable ebook conversion utilising Calibre, this means if you don't require this feature the container isn't uneccessarily bloated but should you require it, it is easily available.
   This optional layer will be rebuilt automatically on our CI pipeline upon new Calibre releases so you can stay up to date.
