Thanks for the pointers.

Unfortunately, that lists the releases, but doesn't explain what
changes they contain.

Also, http://minnow.cc.gatech.edu/squeak/2940 has some clues, but
stops at 3.4.  I also can't tell from it VM changes vs image changes.

I recall seeing that VM numbering had been decoupled from image
numbering, but I haven't been able to (re?)locate that statement.

Yes, I had the same problem.

Can I combine any 3.* series image with any 3.* series VM?

If I get a new VM, do I want to take a new .sources file or any other
file?  My guess is no, because I need to keep my image file.  That
means, I think, I need to keep my .changes file, which in turn means I
need to keep the .sources.  (Also, maybe .sources doesn't change
between major releases?).

Instead, I suppose I should do the online update to get the latest
code changes... does that require any particular VM (this should be
the same as the question of whether any image file goes with any VM, I
think)?

P.S. Though all this talk of licenses is entertaining, if anyone could
answer my original question in this thread about debugging and
critical sections I'd really appreciate it.
