1.2.2:
- Testing on Python 3.5 now uses Python 3.5.3 due to SSL changes. See
  :issue:`943`.
- Linux CI has been updated from Ubuntu 12.04 to Ubuntu 14.04 since
  the former has reached EOL.
- Linux CI now tests on PyPy2 5.7.1, updated from PyPy2 5.6.0.
- Linux CI now tests on PyPy3 3.5-5.7.1-beta, updated from PyPy3
  3.3-5.5-alpha.
- Python 2 sockets are compatible with the ``SOCK_CLOEXEC`` flag found
  on Linux. They no longer pass the socket type or protocol to
  ``getaddrinfo`` when ``connect`` is called. Reported in :issue:`944`
  by Bernie Hackett.
- Replace ``optparse`` module with ``argparse``. See :issue:`947`.
- Update to version 1.3.1 of ``tblib`` to fix :issue:`954`,
  reported by ml31415.
- Fix the name of the ``type`` parameter to
  :func:`gevent.socket.getaddrinfo` to be correct on Python 3. This
  would cause callers using keyword arguments to raise a :exc:`TypeError`.
  Reported in :issue:`960` by js6626069. Likewise, correct the
  argument names for ``fromfd`` and ``socketpair`` on Python 2,
  although they cannot be called with keyword arguments under CPython.

  .. note:: The ``gethost*`` functions take different argument names
            under CPython and PyPy. gevent follows the CPython
            convention, although these functions cannot be called with
            keyword arguments on CPython.
- The previously-singleton exception objects ``FileObjectClosed`` and
  ``cancel_wait_ex`` were converted to classes. On Python 3, an
  exception object is stateful, including references to its context
  and possibly traceback, which could lead to objects remaining alive
  longer than intended.
- Make sure that ``python -m gevent.monkey <script>`` runs code in the
  global scope, not the scope of the ``main`` function.
