mitchduncan let's us know that on the Japanese Pro-G website you can find a 'new' version of Nero Burning Rom with version number 5.5.8.1.
The latest version on the official Ahead download page is 5.5.8.0 so the changes are probably minimal.
You can download this new version here directly if you think it's worth upgrading. The Japanese Pro-G website can be found here and you can use Babel Fish to translate the page.
