Unless I missed something, the most recent updates for the Topaz Labs plugins occurred in november 2011. I can see other plugins that were updated in may 2011 (almost one year ago) and even others that are much older. I also see that a new "Change logs" forum has been opened but it remains desperately empty.
On the other hand, I guess that all these products are far from being in a bug free state and that they deserve at least some tweaking.
So, as a loyal customer, I'm wondering about the future of this product line. A few words from the Topaz Labs team would be in order.
