Correctly update NEWS.rst for the 0.6.0 release.

0.6.0

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

* Issue `16 <https://github.com/jazzband/contextlib2/issues/16>`__:
Backport `AbstractContextManager` from Python 3.6 and `nullcontext`
from Python 3.7 (patch by John Vandenberg)

0.5.5

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

* Issue `13 <https://github.com/jazzband/contextlib2/issues/13>`__:
``setup.py`` now falls back to plain ``distutils`` if ``setuptools`` is not
available (patch by Allan Harwood)

* Updates to the default compatibility testing matrix:

* Added: PyPy3, CPython 3.6 (maintenance), CPython 3.7 (development)
* Dropped: CPython 3.3

0.5.4

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

* Thanks to the welcome efforts of Jannis Leidel, contextlib2 is now a
[Jazzband](https://jazzband.co/) project! This means that I (Nick Coghlan)
am no longer a single point of failure for backports of future contextlib
updates to earlier Python versions.

* Issue `7 <https://github.com/jazzband/contextlib2/issues/7>`__: Backported
fix for CPython issue `27122 <http://bugs.python.org/issue27122>`__,
preventing a potential infinite loop on Python 3.5 when handling
``RuntimeError`` (CPython updates by Gregory P. Smith & Serhiy Storchaka)

0.5.3

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

* ``ExitStack`` now correctly handles context managers implemented as old-style
classes in Python 2.x (such as ``codecs.StreamReader`` and
``codecs.StreamWriter``)

* ``setup.py`` has been migrated to setuptools and configured to emit a
universal wheel file by default

0.5.2

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

* 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)

0.5.1

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

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

* README converted back to reStructured Text formatting

0.5.0

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

* 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)

0.4.0

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

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

* Fall back to unittest2 if unittest is missing required functionality

0.3.1

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

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

0.3

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

* (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)

0.2

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

* Renamed CleanupManager to ContextStack (hopefully before anyone started
using the module for anything, since I didn't alias the old name at all)

0.1

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

* Initial release as a backport module
* Added CleanupManager (based on a `Python feature request`_)
* Added ContextDecorator.refresh_cm() (based on a `Python tracker issue`_)
