[Numpy-discussion] Release notes please; possible bugs

It is turning out to be much more of a headache moving from
numpy-0.9.x to numpy-1.0b1 than it ever was moving from Numeric
to numpy. Could someone please throw together some release
notes (the scipy & sourceforge RN pages are blank) or a Wiki
page warning what has to be changed? Here are some stumbling
blocks I've come across:
* Type names are all now lower case. I know this started
happening late in 0.9.x, but I only know it by accident, via
some email from Travis. This is just one example of the kind
of change that really needs to be prominently noted somewhere.
* .nonzero() now returns a 1-tuple with an array of indices,
for a 1-d array. Before it returned an array of indices.
* In the C API, ContiguousFromObject is now ContiguousFromAny.
I am surprised that my libraries compile with no errors; I
only get a runtime error. Shouldn't I be warned about this
* mtrand still uses ContiguousFromObject in a few places; these
give exceptions when you call, e.g., setstate.
* rand, fft, ift are no longer in the numpy namespace. Is
this a permanent change or a bug?
There are probably other obstacles I'll come across, but this
is what I encountered in code that ran perfectly with 0.9.6.
After several hours of work it's still not running.
