Yes, you're right! I saved a copy of the original-for-ParserComp ZIP. I should upload it and mark it as such, even though it has some obvious bugs I cringe at. And yes, it also causes a problem with save states between versions--I put in a topic at intfiction.org on how to get around that.
The middle 2 point-releases could be recreated, because I have source control. (If you have them, I'd be glad to add them.)
I took the IFComp path of just having the 1st release and the final one available, as I want to limit my fixes to the technical side, and also to something extremely unlikely to regress with proper testing.
