               Stackless Python 1.2
           A Python Implementation That
             Does Not Use The C Stack

               * plus the real toy *

              Continuation Module 0.9
        Continuations as First Class Objects
            with support for MicroThreads

What is it?
A plugin-replacement for core Python.
It should run any program which runs under Python 1.5.2 .
But it does not need space on the C stack.

Major changes in this release:
Extra reference counting reduces continuation frame creation
Better exception handling avoids cycles.

Next to come:
- A port to Python 2.0 will be the first thing to do.
- Long-term project is a complete redesign and
  rewrite for inclusion with Python 2.1
