changes in Matplotlib for scipy backend require current SVN scipy_core

This is just a heads up to those using the scipy backend for matplotlib, that CVS matplotlib contains the changes needed to coincide with the SVN version of scipy_core. This means that if you use CVS matplotlib, you will need a current version of scipy_core out of SVN to use scipy as a backend. The new scipy_core also has a scipy.base.mlab file to be completely backwards compatible (this simplifies the matplotlib.mlab file considerably).

A release of scipy_core with the new module structure for linear algebra, ffts, and random numbers will be made by the first of the year.
