I see the latest open bug in the this mod's bug tracker was posted May 5th, re: logging in as existing customer with shared SSL. Since there are five bug reports on the tracker that have not been addressed since March 23, I sympathize with beta testers who are reluctant to install 3.0.0 beta1.
I'm running this mod with no problems on my hardware catalog, but that's just one environment. While it pales in comparison to the time and effort invested by Josh (aka Dreamscape), I have logged several hours finding and reporting beta bugs -- all of which Josh fixed with impressive speed and agility.
Saying so for the developer's consideration, I was (and still am) happy to beta test Ultimate SEO URLs. But for me this is not an academic exercise. Like so many others, I want and need to utilize a working production release in my stores. I sincerely hope Josh's absence from his own bug tracker these past several weeks comes from an abundance of high-paying contracts, and not from his loss of interest in Chemo's.
Dreamscape, if you're reading this, please let us know how you're faring these days.
