======================================= 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: https://pypy.org/download.html 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. .. _`pypy 2.2 and cpython 2.7.2`: https://speed.pypy.org 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
