[Closed] Update reporting is rather annoying...

Hello,
We love your theme, we have used it on several projects! However, we're using version 6.x-1.7! So everytime we run update we get a "critical" update warning, just to update to 6.x-2.0--- . We love 1.7... we're NOT going to upgrade... the new 2.0 branch is drastically different, requiring us to install other themes that make this one a subtheme. Please, is there any way that 1.7 could not be called to be upgraded, at least critically? I don't know exactly how the version reporting/upgrade reporting works with drupal... so I don't know if this is something for 1.7 to do, or for 2.0 to do... but maybe there's a fix, like changing some files in the 1.7 folder so it doesn't register with you as being in use by us?

As I understand it, there isn't actually a major SECURITY issue with 1.7. Is this correct? or am I missing something.
Once again, Love the theme! (and all the work we put into customizing our versions of it!)
Thanks again.
