Hi all, at the end of July David answered my question about future 64-bit Windows support as follows: "There were some discussion about pushing 1.4.0 'early', but instead, I think we let it slipped - one consequence is that there will be enough time for 1.4.0 to be released with proper AMD64 support on windows. The real issue is not numpy per-se, but making scipy work on top of numpy in 64 bits mode. It is hard to give an exact date as to when those issues will be fixed, but it is being worked on." As our project needs 64-bit numpy under Windows quite soon, I am curious about the state of the project: - Is a stable 64-bit Windows installer (with or without numpy 1.4.0) going to be released anytime SOON? - We need only numpy, not scipy. Does that imply that we have a good chance of producing an install ourselves with the current sources? I am a bit concerned, because earlier posts indicated that the issue is not trivial. Or have all the hard aspects to do with scipy? Thanks for an update! Cheers, Klaus Nökel
