 * diff() can now properly detect renames, both in patch and raw format. Previously it only worked when create_patch was True.
 * repo.odb.update_cache() is now called automatically after fetch and pull operations. In case you did that in your own code, you might want to remove your line to prevent a double-update that causes unnecessary IO.
 * A list of all fixed issues can be found here: https://github.com/gitpython-developers/GitPython/issues?q=milestone%3A%22v0.3.5+-+bugfixes%22+
+* `Repo(path)` will not automatically search upstream anymore and find any git directory on its way up. If you need that behaviour, you can turn it back on using the new `search_parent_directories=True` flag when constructing a `Repo` object.
