I thought about it some more, and a backwards compatible release with numpy
1.4.1 that is also compatible with numpy 2.0 is not even possible. And
compatibility with 1.4.0 is not nearly as useful. So two releases would
really make sense: 0.8 built against numpy 1.4.1 and 0.9 against numpy 2.0
with py3k compatibility.

Here's a proposal for the release schedule:
30/05: create 0.8.x branch, beta available, trunk open to add py3k
compatibility
11/06: 0.8 release candidate 1
22/06: 0.8 release

15/08: create 0.9.x branch, first beta
22/08: 0.9 release candidate 1
01/09: 0.9 release

How does this sound?
