Hi, everybody,

after trials and tribulations I have the honor to announce new release
of M2Crypto 0.25.0. This is an intermediary version on our way towards
port to python 3 (or rather to the bi-versional state of both py2k and
py3k compatibility). Particularly we have made these achievements (whole
changelog since 0.21.1 follows, because I am not sure whether previous
changes were properly announced).

Of course any help on python3 porting branch
(https://gitlab.com/m2crypto/m2crypto/merge_requests/65) is very welcome!

Happy security hacking!
