Comment (by jpflori):
I've had a quick look at the failing doctests and think there is no real
problem hidden there.
The only thing which may be a little distrubing is that now we print
{{{
(2*x+1)*x^2
}}}
rather than
{{{
x^2*(2*x+1)
}}}
This should be easily fixed in pynac hopefully, but even if not I don't
think it should be a blocker.
The other disturbing thing is than fractions get automatically modified
when they used not to be:
{{{
File "devel/sage/doc/ru/tutorial/introduction.rst", line 49, in
doc.ru.tutorial.introduction
Failed example:
k = 1/(sqrt(3)*I + 3/4 + sqrt(73)*5/9); k
Expected:
1/(I*sqrt(3) + 5/9*sqrt(73) + 3/4)
Got:
36/(20*sqrt(73) + 36*I*sqrt(3) + 27)
}}}
Apart from that we also get a lot of nicer things now (in addition to bug
fixes) than before.
