Hi all,

Mpmath version 0.11 is now available from the website:

It can also be downloaded from the Python Package Index:

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

This versions adds speed improvements, many new mathematical functions
(Bessel functions, polylogarithms, Fibonacci numbers, the Barnes G-function,
generalized Stieltjes constants, inverse error function, generalized
incomplete gamma function, etc), a high-precision ODE solver, improved
algorithms for infinite sums and products, calculation of Taylor and Fourier
series, and multidimensional rootfinding, besides many other improvements
and bugfixes. The documentation has also been greatly extended.

For a more detailed review of the new features, see the following blog post:
