SymPy 1.0 was released recently and Anaconda 4.0 was just released. I tried all the sample solutions and everything works as expected. The chapter programs should keep working as well.
You can get both the updates when you install Anaconda 4.0 or updated your existing Anaconda installation:
$ conda update conda $ conda update anaconda
I have so far verified both on Mac OS X and Linux. If you find any issues on Windows, please email me at doingmathwithpython@gmail.com or post your query/tip to any of the following community forums:
