+pytest-2.7.1: bug fixes
+=======================
+
+pytest is a mature Python testing tool with more than a 1100 tests
+against itself, passing on many different interpreters and platforms.
+This release is supposed to be drop-in compatible to 2.7.0.
+
+See below for the changes and see docs at:
+
+    http://pytest.org
+
+As usual, you can upgrade from pypi via::
+
+    pip install -U pytest
+
+Thanks to all who contributed to this release, among them:
+
+    Bruno Oliveira
+    Holger Krekel
+    Ionel Maries Cristian
+    Floris Bruynooghe
+
+Happy testing,
+The py.test Development Team

+2.7.1 (compared to 2.7.0)
+-------------------------
+
+- fix issue731: do not get confused by the braces which may be present
+  and unbalanced in an object's repr while collapsing False
+  explanations.  Thanks Carl Meyer for the report and test case.
+
+- fix issue553: properly handling inspect.getsourcelines failures in
+  FixtureLookupError which would lead to to an internal error,
+  obfuscating the original problem. Thanks talljosh for initial
+  diagnose/patch and Bruno Oliveira for final patch.
+
+- fix issue660: properly report scope-mismatch-access errors
+  independently from ordering of fixture arguments.  Also
+  avoid the pytest internal traceback which does not provide
+  information to the user. Thanks Holger Krekel.
+
+- streamlined and documented release process.  Also all versions
+  (in setup.py and documentation generation) are now read
+  from _pytest/__init__.py. Thanks Holger Krekel.
+
+- fixed docs to remove the notion that yield-fixtures are experimental.
+  They are here to stay :)  Thanks Bruno Oliveira.
+
+- Support building wheels by using environment markers for the
+  requirements.  Thanks Ionel Maries Cristian.
+
+- fixed regression to 2.6.4 which surfaced e.g. in lost stdout capture printing
+  when tests raised SystemExit. Thanks Holger Krekel.
+
+- reintroduced _pytest fixture of the pytester plugin which is used
+  at least by pytest-xdist.
