BC requires a new image format and VM, which requires a MAJOR release since old
images won't work on the new VM and vice versa. Tim has named this major
release VI4 (Virtual Image 4.0) and will likely include other image format

After an image is converted to the new format everything should work as before.
Note the conversion does change a lot of things, notably the Process class and
related classes like MethodContext etc, and the Compiler classes and related
classes including references to compiler classes in Etoys.

I think it is pretty stable, I use it every day. There are still several
things that need to be done and fixed (see the To-Do list on the "Block Closure
Version" swiki page). I will address most of these in my next release (BC
version 3) probably a few months from now. Right now I'm working on a
distributed Squeak architecture that I would also like to see go into VI4. I
will write something about it soon.
