 Announcing Numexpr 1.4.2

Numexpr is a fast numerical expression evaluator for NumPy.  With it,
expressions that operate on arrays (like "3*a+4*b") are accelerated
and use less memory than doing the same calculation in Python.

What's new

This is a maintenance release.  The most annying issues have been
fixed (including the reduction bugs introduced in 1.4 series).
Also, several performance enhancements are included too.
