I had a quick look at it. I think it goes down better than sympy-0.6.7,
there are a few minor doctests to fix (some answers are now x+2 instead of
2+x) but some code in sage needs adjusting before we ship:
File "/usr/share/sage/devel/sage-main/sage/calculus/test_sympy.py", line
294, in __main__.example_0
Failed example:
f = e.series(x, Integer(0), Integer(10)); f###line 111:_sage_ >>> f =
e.series(x, 0, 10); f
Exception raised:
Traceback (most recent call last):

That's the only major problem I detected.
