This document addresses the difference between SimPy versions
1.4.2 and 1.4.1 in terms of changes and additions.


Changes
=========

Histogram
---------
	- class Histogram has been added to modules SimulationRT,
	SimulationTrace and SimulationStep. It had been accidentally
	omitted.


testSimpy.py, Monitortest.py
----------------------------

	- An error in the tests for monitored Resource queues has been fixed. 

SimulationTrace
----------------

	- This module now also accepts the "yield hold,self" form which defaults to
	zero delay.

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

testSimPyRT, testSimPyTrace, testSimPyStep
-------------------------------------------

	- These unittest modules have been added. They test the respective
	simulation modules with exactly the same tests as testSimPy tests
	module Simulation. Thus, they test for compattibility.
