You meant 1.4.0, right ? The trunk requires numpy 1.4.0 for quite a
while, and making it supporting 1.3.0 is out of the question (because
we use the npymath library support, which could not be reused in numpy
1.3.0).

Although I would prefer making scipy 0.8.0 support numpy 1.4.0, it
seems that supporting python 3.x in scipy would be easier if we made
it depend on numpy 2.0 (so that we can add things in numpy to help).

If people think making scipy 0.8.0 python 3.x worths it, it is doable
in a short amount of time (that is it won't postpone scipy 0.8.0
release).

I think this is a good timeline. There has been a lot of new features
in scipy, some quite useful (stats, sparse SVD, etc...).

cheers,
