During the original discussion, Gael pointed out that the changes would probably break some code (which might need to be cleaned up but still). I think it was underestimated how quickly people would upgrade and see the changes and therefore be able to report problems.
We are talking about a 1.7 release, but there are still people who have not upgraded their code to use 1.6 (when some of the big changes occurred).
This should probably guide our view of how long it takes to migrate behavior in NumPy and minimize migration difficulties for users.

> Yes, unless I'm wrong I experienced these problems from 1.5.something to 1.6.1. I didn't take notes as it was in the middle of a deadline-crunch so I just fixed the code and moved on (long, stupid story about why the upgrade before a deadline...). It's just that the issues mentioned above seem to have hit me too and I wanted to mention that. But unhelpfully, I think, without code, and now I've hijacked this thread! Sorry.
