And you've made some cosmetic changes to the client-side code that uses the 'FogBugz engine' (back-end code).
And now you're spouting really insipid bullshit about "Big Bugs". Please excuse my intense skepticism about that being anything other than nothing.
There's a few things I still like about FogBugz versus its 'competitors' – creating a 'case' (issue/ticket) from an email, being able to create hierarchical trees of cases, and being able to search cases. But everything else has been stale for a long time.
You don't even have real integrated version control! Kiln is about as basic of a web wrapper around Git as possible. Or maybe the code reviews are okay? I don't know. I've never used them nor ever heard or read of anyone else doing so either. Why's Kiln off on its own? Hosting a Git repo isn't exactly trivial if you're offering it for free, but you killed the free plan a while ago and I don't think anywhere near as many people as are using GitHub have ever even known of Kiln.
The propose UX improvements are also very very un-inspiring. To whom is FogBugz – I mean Manuscript – going to be marketed? Because it certainly doesn't seem to be programmers.
