[Cryptography-dev] [Proposal] Intent to deprecate and remove: Python 2.6

Hi all,

To wrap a bow on this: on reviewing data from PyPI, it looks like a
significant percentage of Paramiko users are on 2.6. There's currently an
outstanding PR to port paramiko to use cryptography, and IMO that's more
important than dropping 2.6 for overall user security, so I'm going to drop
this until such time as the data supports it, unless anyone wants to argue
in favor vigorously.
