I have been heavily using Photo AI/Photo for a year now (subscription just extended), and I am impressed about its development. However, I am more and more reluctant to upgrade to new versions as they often contain quite heavy bugs, affecting at least some users.
Relying on Topaz Photo, I need a version which is bug free, at least now and then. Version 1.4.1 has been working for me pretty flawless, except the nasty Remove Issue. Having to switch back and forth between Auto and CPU may be a short-term workaround, but not a solution for months.
To make a positive suggestion: Please release a version 1.4.2 with Remove 1 added back (which was really good as well). This would be a perfect workhorse for me for quite some time.
As a sidenote: It might be a clever solution to have a stable version (which 1.4.2 would be) and a most recent version (like 1.5) installed in parallel (which I think isn’t possible right now).
