This document addresses the difference between SimPy versions 1.7 and version 1.7.1 in terms of changes and additions.

Changes

Repaired a bug in the _get methods of Store and Level which could lead to synchronization problems (blocking of producer processes, despite space being available in the buffer).
Repaired Level __init__ method to allow initialBuffered to be of either float or int type.

Additions

Added type test for Level get parameter 'nrToGet' to limit it to positive int or float.
To improve pretty-printed output of 'Level' objects, changed attribute '_nrBuffered' to 'nrBuffered' (synonym for 'amount' property)
To improve pretty-printed output of 'Store' objects, added attribute 'buffered' (which refers to '_theBuffer')
