+=======================================
+PyPy 2.2.1 - Incrementalism.1
+=======================================
+
+We're pleased to announce PyPy 2.2.1, which targets version 2.7.3 of the Python
+language. This is a bugfix release over 2.2.
+
+You can download the PyPy 2.2.1 release here:
+

+
+What is PyPy?
+=============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7. It's fast (`pypy 2.2 and cpython 2.7.2`_ performance comparison)
+due to its integrated tracing JIT compiler.
+
+This release supports x86 machines running Linux 32/64, Mac OS X 64, Windows
+32, or ARM (ARMv6 or ARMv7, with VFPv3).
+
+Work on the native Windows 64 is still stalling, we would welcome a volunteer
+to handle that.
+

+
+Highlights
+==========
+
+This is a bugfix release.  The most important bugs fixed are:
+
+* an issue in sockets' reference counting emulation, showing up
+  notably when using the ssl module and calling ``makefile()``.
+
+* Tkinter support on Windows.
+
+* If sys.maxunicode==65535 (on Windows and maybe OS/X), the json
+  decoder incorrectly decoded surrogate pairs.
+
+* some FreeBSD fixes.
+
+Note that CFFI 0.8.1 was released.  Both versions 0.8 and 0.8.1 are
+compatible with both PyPy 2.2 and 2.2.1.
+
+
+Cheers,
+Armin Rigo & everybody
