This document addresses the difference between SimPy versions
1.9 and version 1.9.1 in terms of changes and additions.
  
Repairs
========

This bug-fix release cures the following bugs:

- Excessive production of circular garbage, due to a circular reference
  between Process instances and event notices. This led to large memory
  requirements.
  
- Runtime error for preempts of proceeses holding multiple Resource objects.


Additions
============

- A Short Manual, describing only the basic facilities of SimPy.
