17.02.2015 (v0.8.5):
  - Fixed: security issues with SSL. We now use TLS rather than SSLv3,
           and autonegotiate the strongest version of TLS we can get,
           since all versions of pre-TLS SSL are widely deprecated
           at this point (POODLE attack finally killed SSLv3).
  - Removed: internal support for HTTP/HTTPS proxies:
           there are better options readily available as external tools,
           and removing the internal code makes it much easier to
           reason about our own security and general correctness.
