Matplotlib is incompatible with NumPy 1.0rc3

Once when I found that NumPy released its version 1.0rc3,
I happily upgraded NumPy from 1.0rc1 to 1.0rc3 under WindowsXP.
A nightmare just happened. Matplotlib failed to run with NumPy 1.0
and I cannot found a NumPy 1.0rc1 on its download page.
Will matplotlib upgrade for NumPy 1.0rc3?
What can I do for this?
Grateful to any suggestion.


Nature uses only the longest threads to weave her patterns,
so each small piece of her fabric reveals the organization of the entire tapestry.
