Hi all,

Version 0.17 of mpmath is now available on the project 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
(, and is also available as a standard
component of Sage (

The major news in 0.17 is that mpmath now works with Python 3. To
support both Python 2.x and 3.x with the same codebase, compatibility with
Python 2.4 has been dropped (mpmath now requires 2.5 or higher). New
functionality in mpmath 0.17 includes an implementation of the Lerch
transcendent, Riemann zeta zero counting, and improved support for
evaluating derivatives of the Hurwitz zeta function and related functions.

Many thanks to Juan Arias de Reyna and Case Vanhorsen who contributed
to this version.
