Version 1.1.0
=============
- Improve support for Python 3.
- ALGORITHM CHANGE: only diff tree with first parent.
Running ``git deps`` on ``FOO^!`` is effectively answering the
question "which commits would I need in order to be able to cleanly
cherry-pick commit ``FOO``?" Drilling down further, that could be
rephrased more precisely as "which commits would I need in my
current branch in order to be able to cleanly apply the diff which
commit ``FOO`` applies to its parent?"
However, in the case where ``FOO`` is a merge commit with multiple
parents, typically the first parent ``P1`` is the parent which is
contained by the merge's target branch ``B1``. That means that the
merge commit ``FOO`` has the effect of applying the diff between
``P1``'s tree and the ``FOO``'s tree to ``P1``. This could be
expressed as::
tree(P1) + diff(tree(P1), tree(FOO)) == tree(FOO)
Therefore the question ``git deps`` needs to answer when operating
on a commit with multiple parents is "which commits would I need in
my current branch in order to be able to cleanly apply
``diff(tree(P1), tree(FOO))`` to it?"
However, the current algorithm runs the blame analysis not only on
``diff(tree(P1), tree(FOO))``, but on ``diff(tree(Px), tree(FOO))``
for *every* parent. This is problematic, because for instance if
the target branch contains commits which are not on ``P2``'s
branch, then::
diff(tree(P2), tree(FOO))
will regress any changes provided by those commits. This will
introduce extra dependencies which incorrectly answer the above
question we are trying to answer.
Therefore change the algorithm to only diff against the first parent.
This is very similar in nature to the ``-m`` option of ``git cherry-pick``:

In the future it may be desirable to add an analogous ``-m`` option
to ``git deps``.
- Add ``git-fixup``.
- Allow clean interruption via ``Control+C``.
- Fix output buffering issue.
- Upgrade jQuery.
- Improve debugging output.
- Refactor internals.
- Improve documentation.
Version 1.0.2
=============
- Improve documentation.
- Add a guide for maintainers.
- Add a tox environment for sdist building.
Version 1.0.1
=============
- Update dagre Javascript module to address security issues.
- Documentation improvements.
- Avoid PyScaffold bug.
- Repackage Javascript modules using newer npm, to avoid problem
with timestamps which causes building of wheels to fail:

Version 1.0.0
=============
- Turned into a proper Python module, using PyScaffold.
