 Announcing Numexpr 2.0.1

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.

It wears multi-threaded capabilities, as well as support for Intel's
VML library, which allows for squeezing the last drop of performance
out of your multi-core processors.

What's new

In this release, better docstrings for `evaluate` and reduction
methods (`sum`, `prod`) is in place.  Also, compatibility with Python
2.5 has been restored (2.4 is definitely not supported anymore).

In case you want to know more in detail what has changed in this
version, see:


or have a look at RELEASE_NOTES.txt in the tarball.

Where I can find Numexpr?

The project is hosted at Google code in:


You can get the packages from PyPI as well:
