SVN version support for VS addin

Hi,

Our TC installation's VS addin (v 8.0.6 EAP build 27703) only supports SVN up to version 1.7. Our SVN tool is 1.8.5.

Is a newer version of the VS addin available which supports more recent versions of SVN?
Is it possible to obtain that addin without upgrading our TC installation?

Thanks,
    Bob
