    Announcing NumExpr 2.9.0
    ========================

    Hi everyone,

    NumExpr 2.9.0 is a release offering support for latest versions of PyPy.
    The full test suite should pass now, at least for the Python 3.10 version. Thanks to @27rabbitlt for most of the work and @mgorny and @mattip for providing help and additional fixes.

    Project documentation is available at:

    http://numexpr.readthedocs.io/

    Changes from 2.8.8 to 2.9.0
    ---------------------------

    * Support for PyPy (see PRs #467 and #740). The full test suite
    should pass now, at least for the 3.10 version. Thanks to
    @27rabbitlt for most of the work and @mgorny and @mattip for
    providing help and additional fixes. Fixes #463.

    * Fixed more sanitizer issues (see PR #469). Thanks to @27rabbitlt.

    * Modernized the test suite to avoid some warnings.

    What's Numexpr?
    ---------------

    Numexpr is a fast numerical expression evaluator for NumPy. With it, expressions that operate on arrays (like "3*a+4*b") are accelerated
    and use less memory than doing the same calculation in Python.

    It has multi-threaded capabilities, as well as support for Intel's
    MKL (Math Kernel Library), which allows an extremely fast evaluation
    of transcendental functions (sin, cos, tan, exp, log...) while
    squeezing the last drop of performance out of your multi-core
    processors. Look here for a some benchmarks of numexpr using MKL:

    https://github.com/pydata/numexpr/wiki/NumexprMKL

    Its only dependency is NumPy (MKL is optional), so it works well as an easy-to-deploy, easy-to-use, computational engine for projects that
    don't want to adopt other solutions requiring more heavy dependencies.

    Where I can find Numexpr?
    -------------------------

    The project is hosted at GitHub in:
