1.13.0 - 2017-05-03
-------------------

New Features:
  * The buffer returned by :meth:`ImageSurface.get_data` under Python 2 now
    implements the character buffer interface to make it work with
    pygame.image.frombuffer(). :pr:`29`

    All relevant constants are now an alias to attributes of those types e.g.
    :data:`ANTIALIAS_DEFAULT` is the same as :attr:`Antialias.DEFAULT`.

    All functions returning enum values now return instances of the new types
    e.g. :meth:`Context.get_antialias` returns a :class:`Antialias`.

    :attr:`Error.status` is now a :class:`Status`.
  * All included examples now work with Python 2 & 3
  * All included examples using GTK+ have been ported to GTK+ 3/PyGObject 3

Fixes:
  * Fix the signature of the :class:`ImageSurface` buffer interface for Python 2
    (int -> Py_ssize_t)
  * setup.py: Ensure "-fno-strict-aliasing" is used with Python 2.

Testing:
  * Added travis-ci tests for flake8 and sphinx. :pr:`30`, :pr:`32`

.. _v1.11.1:

1.11.1 - 2017-04-12
-------------------

This release fixes an ABI breakage. I missed that the original pycairo master
had already broken ABI compared to 1.10.0.

.. _v1.11.0:

1.11.0 - 2017-04-09
-------------------

This version is based on the Python 2 version of pycairo 1.10.0 and is API/ABI
compatible with both py2cairo 1.10.0 and py3cairo 1.10.0.

General Changes:
    * Requires cairo 1.10.2+
    * Switch to semantic versioning
    * Switch build system to distutils/setup.py (xpyb integration can be
      enabled with passing ``--enable-xpyb`` to setup.py build)
    * Moved to GitHub: https://github.com/pygobject/pycairo

New Features:
    * Python 3 support (API/ABI compatible with py3cairo 1.10.0) including
      support for :exc:`cairo.Error`, :meth:`cairo.ImageSurface.get_data` and
      :meth:`cairo.ImageSurface.create_for_data`, which were missing in
      py3cairo.
    * :class:`cairo.RecordingSurface` (:fdobug:`36854`,
      `Torsten Landschoff <t.landschoff@gmx.net>`__)
    * :class:`cairo.Region`, :class:`cairo.RectangleInt` and
      cairo.REGION_OVERLAP_*
      (:fdobug:`44336`, `Bug Fly <mozbugbox@yahoo.com.au>`__)

Bug Fixes:
    * Fix crash when read()/write() methods of file objects passed to pycairo
      raise exceptions.
    * Fix possible value truncation of handles passed to Win32Surface and
      Win32PrintingSurface on 64bit Windows. :fdobug:`57493`
