Release candidate 2 for NumPy 1.4.1 and SciPy 0.7.2


I am pleased to announce the second release candidate of both
Scipy 0.7.2 and NumPy 1.4.1. Please test, and report any problems on the NumPy or SciPy list. I also want to specifically ask you to report success/failure with other libraries (Matplotlib, Pygame, ) based on NumPy or SciPy.

Binaries, sources and release notes can be found at

NumPy 1.4.1


The main change over 1.4.0 is that datetime support has been removed. This fixes the binary incompatibility issues between NumPy and other libraries like SciPy and Matplotlib.

There are also a number of other bug fixes, and no new features.

Binaries for Python 2.5 and 2.6 are available for both Windows and OS X.

SciPy 0.7.2

The only change compared to 0.7.1 is that the C sources for Cython code have been regenerated with Cython 0.12.1. This ensures that SciPy 0.7.2 will work with NumPy 1.4.1, while also retaining backwards compatibility with NumPy 1.3.0.

Note that the 0.7.x branch was created in January 2009, so a lot of fixes and new functionality in current trunk is not present in this release.

Binaries for Python 2.6 are available for both Windows and OS X. Due to the age of the code no binaries for Python 2.5 are available.
