Mavericks compatibility with SmartSVN 6.6

Hi,

I have a license for SmartSVN 6.6.11. I'm currently running OXS 10.6.8 and would like to upgrade to Mavericks, but http://roaringapps.com/apps claims that SmartSVN is not compatible with with Mavericks. Is roaringapps correct? Do I need to purchase an upgrade to SmartSVN to run it on Mavericks?

Thanks,
