Topaz Denoise AI and Sharpen AI support and improvement Abandoned?

Have Denoise AI and Sharpen AI been abandoned for support and improvement? Throughout my year of paid support very few improvements were made and at least one I felt set the product back. My upgrade (to newer versions) expired back in November but I felt I received very little value for my hard to come by money and to be honest was a little disgruntled after supporting Topaz from the early days before the AI products.
Have these two products now gone the way of my Mask AI and adjust AI? I note that Photo AI was improved but the granular adjustments are missing from what little I had in the two stand alone Denoise AI and Sharpen AI. The introduction of the Adobe Denoise further diminished value to me though is very slowwwww.
