pyOpenSSL 0.12 released

Written for pyOpenSSL by Jean-Paul Calderone on 2011-04-12

This release fixes an incompatibility with Python 2.7 involving memoryviews. It also exposes the "info callback" constants used to report progress of the TLS handshake and later steps of SSL connections. Perhaps most interestingly, it also adds support for inspecting arbitrary X509 extensions.
