Hi all,

Mpmath version 0.12 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

Version 0.12 mostly contains bug fixes and speed improvements. New features
include various special functions from analytic number theory, Newton's method
as an option for root-finding, and more versatile printing of intervals. It is
now also possible to create multiple working contexts each with its
own precision.
Finally, mpmath now recognizes being installed in Sage and will automatically
wrap Sage's fast integer arithmetic if available.

For more details, see the changelog:
