Hi, Mpmath version 0.10 is now available from the website: http://code.google.com/p/mpmath/ It can also be downloaded from the Python Package Index: http://pypi.python.org/pypi/mpmath/0.10 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/). Additions in 0.10 include plotting support, matrices and linear algebra functions, new root-finding and quadrature algorithms, enhanced interval arithmetic, and some new special functions. Many speed improvements have been committed (a few functions are an order of magnitude faster than in 0.9), and as usual various bugs have been fixed. Importantly, this release fixes mpmath to work with Python 2.6. For a more complete changelog, see: http://mpmath.googlecode.com/svn/trunk/CHANGES Special thanks go to Vinzent Steinberg who contributed the new linear algebra and root-finding code, and to everybody else who made a contribution or provided feedback. Bug reports and other comments are welcome at the issue tracker at http://code.google.com/p/sympy/issues/list or the mpmath mailing list: http://groups.google.com/group/mpmath Fredrik
