So it seems that there is an agreement of breaking the ABI only once
overall. This is good.

In that regard, your proposal is very similar to what was suggested at
the beginning - the difference is only whether breaking at 1.4.x or
I don't care that much about where (1.4.x vs 1.5.x) the datetime is
pushed. But then the hasobject-related changes should be put
altogether, to respect the goal of breaking the ABI only once. If you
think it can be done for the end of february, then I don't see much
point in releasing what you call 1.3.9, because I really don't want to
have to put numpy-version specific scipy/maplotlib/whatever. The
release with datetime changes will be the one to build scipy and
matplotlib against (I will then focus on releasing scipy 0.8.0).
1.4.0 would is then considered as a broken release (I am removing the
files from sourceforge).
