The stdlib is now 2.7.10 and cffi is 1.2.

I think the most interesting change is int-float-list-strategy, at
least in terms of explaining it:

"""Use a compact strategy for Python lists that mix integers and floats,
at least if the integers fit inside 32 bits.  These lists are now
stored as an array of floats, like lists that contain only floats; the
difference is that integers are stored as tagged NaNs.  (This should
have no visible effect!  After ``lst = [42, 42.5]``, the value of
``lst[0]`` is still *not* the float ``42.0`` but the integer ``42``.)"""

Maybe mention that numpy support is getting more and more complete,
and vmprof support is improving.


A bientôt,

Armin.
