-----------------

* Use ``from __future__ import print_function`` to fix output of ``help --rst``.
[fschulze]

* Set empty version pin for develop packages instead of removing the version
pin from the section.
[fschulze]

-----------------

* Add more info on git operations, so one can see which repository is cloned
and which branch is used.
[fschulze]

* Fix git submodules with git 2.x.
[fschulze]

-----------------

* Add the buildout option mr.developer-verbose that enables showing
the same out when running buildout as when running ./bin/develop up -v.
[sunew]

* Respect the buildout -v setting for updates, just as it already does for checkouts.
[sunew]

-----------------

* Do not use the backport of configparser on Python2, to fix
"Option values must be strings" exception on some commands.
[MatthewWilkes]

* No longer test on Python 3.2. [maurits]

* Improve error message when a directory isn't found in fs mode.
[idgserpro]

-----------------

* Remove support for python 2.4 and 2.5. Use python 2.6 or higher or python
3.2 or higher.
[reinout]

* Report missing executables (like 'hg') instead of reporting a too-generic
"file not found" error.
[reinout]

* Fix bug with assignments lacking the section. According to
buildout's documentation ``option=value`` is equivalent to
``buildout:option=value``.
Fixes issue 151
[mvaled]

* Fix switching to git branch from revision. When currently you are
not on a git branch (for example on a tag), running a develop update
would try to pull and fail. Now we simply fetch, and handle
possible branch switching and merging the same as we always do.
Fixes issue 162
[maurits]

* Fix unpinning of eggs with a name containing characters not in [^A-Za-z0-9.]
This means that to correctly unpin pkg.foo_bar we have to delete
``pkg.foo-bar`` from the buildout ``[version]`` section.
[ale-rt (Alessandro Pisa)]

* Checkout branch when cloning a git repository.
[gforcada]

-----------------

* Fix git-clone-depth global option, it needs to be kept as a string and not
converted to a number.
