The rule should be 1.6.x imho. Undoing things that were changed in between
1.5.x and 1.6.x makes very little sense; numpy 1.6.0 has been out for over

I think you are mainly talking here about changes that had unintended
side-effects, and broke things without anyone realizing that in time. If
you read the 1.5.0, 1.6.0 and 1.7.0 release notes, there have been very few
Besides that, we have a long standing policy of removing those things that
do get deprecated after one minor release:
http://projects.scipy.org/numpy/wiki/ApiDeprecation. If you propose to
change that, I suggest discussing it in a separate thread.

Did you happen to see
other things, it lists a few things that are still to be done (merge doc
wiki edits, flip the "raise_warnings" switch) and details on the Wine /
MinGW setup that may be useful. I did just spot a mistake there by the way,
we're still on MinGW 3.4.5.
We are also using this time to 1) setup Continuous Integration services for
