Hi,
the sympy 0.5.4 was released. The main improvements over the 0.5.3 are:
* Log and ApplyLog classes were simplified to log, as was in the
0.4.3 version (the same for all other classes, like sin, cos, etc.),
for the current uptodate documentation see SymPySvn.
* limits algorithm was fixed and it works very reliably (there are
some bugs in the series facility though that make some limits fail),
see this post for more details
* all functions arguments are now accessed using the sin(x)[:]
idiom again, as in the 0.4.3 version (instead of the old sin(x)._args
or sin(x).args which was briefly introduced in the 0.5.x series), see
SymPySvn, section accessing parameters
Known issues:
o the series expansion fails for some more complex
expressions (the same problem since SymPy 0.5.0), see this post for
more details
Thanks everyone for making this happen and fixing issues. I hope to
release more often from now with new changes and fixes. The plan is to
implement nice features from the sympy-sandbox, after discussing them
here or in Issues.
