Version 0.14 of mpmath is now available on the website: http://code.google.com/p/mpmath/
It can also be downloaded from the Python Package Index: http://pypi.python.org/pypi/mpmath/0.14
Mpmath is a pure-Python library for arbitrary-precision floating-point arithmetic that implements an extensive set of mathematical functions. It can be used as a standalone library or via SymPy ( http://code.google.com/p/sympy/), and is also available as a standard component of Sage (http://sagemath.org/).
For a list of new features, see the blog post and changelog: http://fredrik-j.blogspot.com/2010/02/mpmath-014-released.html http://mpmath.googlecode.com/svn/tags/0.14/CHANGES
For a brief summary, the new features in 0.14 include support for using a Cython-based backend soon to be added to Sage (giving a large speedup of mpmath in Sage); support for 3D plotting; fast low-precision functions (using Python's builtin float/complex types); an implementation of the Riemann-Siegel expansion for the Riemann zeta function; many improvements to evaluation of hypergeometric functions; miscellaneous new special functions; matrix functions; and several bugfixes and optimizations.
Extensive documentation is available at: http://mpmath.googlecode.com/svn/trunk/doc/build/index.html (or equivalently) http://mpmath.googlecode.com/svn/tags/0.14/doc/build/index.html
Enjoy, and extra thanks to Juan Arias de Reyna, Vinzent Steinberg, Jorn Baayen and Chris Smith who contributed to this version.
