+py.test 2.1.0: perfected assertions and bug fixes
+===========================================================================
+
+Welcome to the relase of pytest-2.1, a mature testing tool for Python,
+supporting CPython 2.4-3.2, Jython and latest PyPy interpreters.  See
+the improved extensive docs (now also as PDF!) with tested examples here:
+
+     http://pytest.org/
+
+The single biggest news about this release are **perfected assertions**
+courtesy of Benjamin Peterson.  You can now safely use ``assert``
+statements in test modules without having to worry about side effects
+or python optimization ("-OO") options.  This is achieved by rewriting
+assert statements in test modules upon import, using a PEP302 hook.
+See http://pytest.org/assert.html#advanced-assertion-introspection for
+detailed information.  The work has been partly sponsored by my company,
+merlinux GmbH.
+  
+For further details on bug fixes and smaller enhancements see below.
+
+If you want to install or upgrade pytest, just type one of::
+
+    pip install -U pytest # or
+    easy_install -U pytest
+
+best,
