SymPy 0.5.4
5 Oct 2007
LogandApplyLogclasses were simplified tolog, as was in the 0.4.3 version (the same for all other classes, likesinorcos).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 oldsin(x)._argsorsin(x).argswhich was briefly introduced in the 0.5.x series).
