+==============================
+PyPy 2.0.1 - Bohr Smørrebrød
+==============================
+
+We're pleased to announce PyPy 2.0.1.  This is a stable bugfix release
+over 2.0.  You can download it here:
+  
+    http://pypy.org/download.html
+
+The fixes are mainly about fatal errors or crashes in our stdlib.  See
+below for more details.
+
+What is PyPy?
+=============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7. It's fast (`pypy 2.0 and cpython 2.7.3`_ performance comparison)
+due to its integrated tracing JIT compiler.
+
+This release supports x86 machines running Linux 32/64, Mac OS X 64 or
+Windows 32.  Support for ARM is progressing but not bug-free yet.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+- fix an occasional crash in the JIT that ends in `RPython Fatal error:
+  NotImplementedError`__.
+
+- `id(x)` is now always a positive number (expect on int/float/long/complex).
+  This fixes an issue in ``_sqlite.py`` (mostly for 32-bit Linux).
+
+- fix crashes of callback-from-C-functions (with cffi) when used together
+  with Stackless features, on asmgcc (i.e. Linux only).  Now `gevent should
+  work better`__.
+
+- work around an eventlet issue with `socket._decref_socketios()`__.
