and/or file bug reports on Launchpad:


Here is the changelog:

   * Python 3 support!  (Thorsten E. Behrens, Anders Sundman)
     PyCrypto now supports every version of Python from 2.1 through 3.2.

   * Timing-attack countermeasures in _fastmath: When built against
     libgmp version 5 or later, we use mpz_powm_sec instead of mpz_powm.
     This should prevent the timing attack described by Geremy Condra at
     PyCon 2011:

   * New hash modules (for Python >= 2.5 only): SHA224, SHA384, and
     SHA512 (Frédéric Bertolus)

   * Configuration using GNU autoconf.  This should help fix a bunch of
     build issues.

   * Support using MPIR as an alternative to GMP.

   * Improve the test command in setup.py, by allowing tests to be
     performed on a single sub-package or module only. (Legrandin)

     You can now do something like this:

       python setup.py test -m Hash.SHA256 --skip-slow-tests

   * Fix double-decref of "counter" when Cipher object initialisation
     fails (Ryan Kelly)

   * Apply patches from Debian's python-crypto 2.3-3 package (Jan
     Dittberner, Sebastian Ramacher):
    - fix-RSA-generate-exception.patch
    - epydoc-exclude-introspect.patch
    - no-usr-local.patch

   * Fix launchpad bug #702835: "Import key code is not compatible with
     GMP library" (Legrandin)

   * More tests, better documentation, various bugfixes.

Thanks to everyone who helped make this release possible!
