Contextlib2

^^^^^^^^^^^^^^^^^^

* development migrated from BitBucket to GitHub

* ``redirect_stream``, ``redirect_stdout``, ``redirect_stderr`` and ``suppress``
now explicitly inherit from ``object``, ensuring compatibility with
``ExitStack`` when run under Python 2.x (patch contributed by Devin
Jeanpierre).

* ``MANIFEST.in`` is now included in the published sdist, ensuring the archive
can be precisely recreated even without access to the original source repo
(patch contributed by Guy Rozendorn)

^^^^^^^^^^^^^^^^^^

* Python 2.6 compatilibity restored (patch contributed by Armin Ronacher)

* README converted back to reStructured Text formatting

^^^^^^^^^^^^^^^^^^

* Updated to include all features from the Python 3.4 and 3.5 releases of
contextlib (also includes some ``ExitStack`` enhancements made following
the integration into the standard library for Python 3.3)

* The legacy ``ContextStack`` and ``ContextDecorator.refresh_cm`` APIs are
no longer documented and emit ``DeprecationWarning`` when used

* Python 2.6, 3.2 and 3.3 have been dropped from compatibility testing

* tox is now supported for local version compatibility testing (patch by
Marc Abramowitz)

^^^^^^^^^^^^^^^^^^

* (BitBucket) Issue 8: Replace ContextStack with ExitStack (old ContextStack
API retained for backwards compatibility)

* Fall back to unittest2 if unittest is missing required functionality

^^^^^^^^^^^^^^^^^^

* (BitBucket) Issue 7: Add MANIFEST.in so PyPI package contains all relevant
files (patch contributed by Doug Latornell)

^^^^^^^^^^^^^^^^

* (BitBucket) Issue 5: ContextStack.register no longer pointlessly returns the
wrapped function
* (BitBucket) Issue 2: Add examples and recipes section to docs
* (BitBucket) Issue 3: ContextStack.register_exit() now accepts objects with
__exit__ attributes in addition to accepting exit callbacks directly
* (BitBucket) Issue 1: Add ContextStack.preserve() to move all registered
callbacks to a new ContextStack object
* Wrapped callbacks now expose __wrapped__ (for direct callbacks) or __self__
(for context manager methods) attributes to aid in introspection
* Moved version number to a VERSION.txt file (read by both docs and setup.py)
* Added NEWS.rst (and incorporated into documentation)
