-- newdims() switched to reshape()
-- convert() switched to as() and asfloat()
-- alltrue() switched to all()
-- allfalse() switched to any()
-- mpow() switched to matpow()
-- std() switched to stdev()
-- afDevicePointer and afHostPointer have changed to afDevice and afHost


- extended and organized documentation
- simplified and verified all examples
-- support for both Windows Visual 2008 and 2010
-- use timeit() where possible
- integer rand()
- expanded licensing documentation

- Improved code samples in documentation
- added common machine-independent constants: Pi, NaN, Inf



Python Documentation and Release Notes
API Changes
- * operator now performs element wise multiplication not Matrix multiply
- matmul() is introduced for Matrix multiplication
- reshape() has been moved from a method to a function
