-----

* Fixed breakages caused by Subversion 1.4's new "working copy" format

-----

-----

* The ``ez_setup`` module displays the conflicting version of setuptools (and
its installation location) when a script requests a version that's not
available.

* Running ``setup.py develop`` on a setuptools-using project will now install
setuptools if needed, instead of only downloading the egg.

-----

-----

* Fixed ``AttributeError`` when trying to download a ``setup_requires``
dependency when a distribution lacks a ``dependency_links`` setting.

* Made ``zip-safe`` and ``not-zip-safe`` flag files contain a single byte, so
as to play better with packaging tools that complain about zero-length
files.

* Made ``setup.py develop`` respect the ``--no-deps`` option, which it
previously was ignoring.

* Support ``extra_path`` option to ``setup()`` when ``install`` is run in
backward-compatibility mode.

* Source distributions now always include a ``setup.cfg`` file that explicitly
sets ``egg_info`` options such that they produce an identical version number
to the source distribution's version number. (Previously, the default
version number could be different due to the use of ``--tag-date``, or if
the version was overridden on the command line that built the source
distribution.)

-----

-----

* Fix ``register`` not obeying name/version set by ``egg_info`` command, if
``egg_info`` wasn't explicitly run first on the same command line.

* Added ``--no-date`` and ``--no-svn-revision`` options to ``egg_info``
command, to allow suppressing tags configured in ``setup.cfg``.

* Fixed redundant warnings about missing ``README`` file(s); it should now
appear only if you are actually a source distribution.

-----

-----

* Fix ``bdist_egg`` not including files in subdirectories of ``.egg-info``.

* Allow ``.py`` files found by the ``include_package_data`` option to be
automatically included. Remove duplicate data file matches if both
``include_package_data`` and ``package_data`` are used to refer to the same
files.

-----

-----

* Strip ``module`` from the end of compiled extension modules when computing
the name of a ``.py`` loader/wrapper. (Python's import machinery ignores
this suffix when searching for an extension module.)
