Many bugfixes and improvements

Is there a changelog? I'm curious about what bugs were fixed, and what improvements were made.

In particular, was the identify glitch patched, or is it still possible to exploit it?

Yes to both:

I'll post some more detailed thoughts on some of the changes later (and how they compare to other games in the series and other versions), but I actually prefer to have the identify glitch intact, as it's the reason for me to choose the Apple 2 version over other versions.
