Compatible Version of Numpy?

I think that 97.6 was compiled against 1.0rc2 but Charlie Moad is the
authority on this since he did the compile. I have added this "news
flash" to the site

  The latest matplotlib for windows was compiled with numpy
  1.0rc2. Please do not upgrade matplotlib for windows if you are
  running the latest numpy 1.0rc3. Check back soon as we hope to get a
  binary build for the latest numpy ASAP. You can check your numpy
  version by doing

  >>> import numpy
  >>> print numpy.__version

  Note, the latest matplotlib compiles and runs fine against the
  latest numpy -- this only affects binary builds such as the windows
  installer.

Ok, thanks. I suspected that, but since even Google isn't able to find
an rc2 binary, I guess my only option is to wait for a compatible
Matplotlib to be released.

On a loosely-related topic, I originally tried upgrading to try out
pylab.quiver. In earlier versions, the arrows drawn by quiver could
not be properly scaled and were rendered at a huge size. Do you know
if this was a registered bug, and if it's been fixed?

There is a complete re-implementation of quiver with correct scaling and control over arrow shape, size, color, and outline.
