Hi all, Version 0.15 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/0.15 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/). The versions in Sage and SymPy will be updated soon. For details about the new features in this version, see the following blog post and the changelog: http://fredrik-j.blogspot.com/2010/06/announcing-mpmath-015.html http://mpmath.googlecode.com/svn/tags/0.15/CHANGES Briefly, besides many small fixes, 0.15 includes large performance improvements for transcendental functions, new code for computing the nontrivial zeros of the Riemann zeta function (contributed by Juan Arias de Reyna), and many new special functions (including generalized 2D hypergeometric series, q-functions, and new elliptic functions). Support for complex interval arithmetic has also been added. Extensive documentation is available at: http://mpmath.googlecode.com/svn/trunk/doc/build/index.html (or equivalently) http://mpmath.googlecode.com/svn/tags/0.15/doc/build/index.html Bug reports and other comments are welcome on the issue tracker at http://code.google.com/p/mpmath/issues/list or the mpmath mailing list: http://groups.google.com/group/mpmath Enjoy, Fredrik Johansson
