The downloads section of the web page has nothing to download.
There should be a download link to the latest version of the ROME src-zip/jars (as well as links to past versions).
At the very least, there should be a download link to the latest version of the compiled jar file.

ROME recently moved to GitHub. You can find your issue here: https://github.com/rometools/rome/issues/156
