CHANGES

* Drop support for Python 3 < 3.4. This is because
pkg_resources (which get used by setuptools and mock)
no longer supports 3.3 and earlier. (Jelmer Vernooij)

fetching and updating shallow metadata. (Jelmer Vernooij, 240)

BUG FIXES

* Don't write to stdout and stderr when they are not available
(such as is the case for pythonw). (Sylvia van Os, 652)

* Fix compatibility with newer versions of git, which expect CONTENT_LENGTH
to be set to 0 for empty body requests. (Jelmer Vernooij, 657)

* Raise an exception client-side when a caller tries to request
SHAs that are not directly referenced the servers' refs.
(Jelmer Vernooij)

* Raise more informative errors when unable to connect to repository
over SSH or subprocess. (Jelmer Vernooij)

* Handle commit identity fields with multiple ">" characters.
(Nicolas Dandrimont)

* ``dulwich.porcelain.get_object_by_path`` method for easily
accessing a path in another tree. (Jelmer Vernooij)

* Support the ``i18n.commitEncoding`` setting in config.
(Jelmer Vernooij)
