+=======================================
+PyPy 2.2 - Incrementalism
+=======================================
+
+We're pleased to announce PyPy 2.2, which targets version 2.7.3 of the Python
+language. This release main highlight is the introduction of the incremental
+garbage collector, sponsored by the `Raspberry Pi Foundation`_.
+
+This release also contains several bugfixes and performance improvements.
+
+You can download the PyPy 2.2 release here:
+
+ http://pypy.org/download.html
+
+We would like to thank our donors for the continued support of the PyPy
+project. We showed quite a bit of progress on all three projects (see below)
+and we're slowly running out of funds.
+Please consider donating more so we can finish those projects! The three
+projects are:
+
+* Py3k (supporting Python 3.x): the release PyPy3 2.2 is imminent.
+
+* STM (software transactional memory): a preview will be released very soon,
+ as soon as we fix a few bugs
+
+* NumPy: the work done is included in the PyPy 2.2 release. More details below.
+
+.. _`Raspberry Pi Foundation`: http://www.raspberrypi.org
+
+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`: http://speed.pypy.org
+
+Highlights
+==========
+
+* Our Garbage Collector is now "incremental". It should avoid almost
+ all pauses due to a major collection taking place. Previously, it
+ would pause the program (rarely) to walk all live objects, which
+ could take arbitrarily long if your process is using a whole lot of
+ RAM. Now the same work is done in steps. This should make PyPy
+ more responsive, e.g. in games. There are still other pauses, from
+ the GC and the JIT, but they should be on the order of 5
+ milliseconds each.
+
+* The JIT counters for hot code were never reset, which meant that a
+ process running for long enough would eventually JIT-compile more
+ and more rarely executed code. Not only is it useless to compile
+ such code, but as more compiled code means more memory used, this
+ gives the impression of a memory leak. This has been tentatively
+ fixed by decreasing the counters from time to time.
+
+* NumPy has been split: now PyPy only contains the core module, called
+ ``_numpypy``. The ``numpy`` module itself has been moved to
+ ``https://bitbucket.org/pypy/numpy`` and ``numpypy`` disappeared.
+ You need to install NumPy separately with a virtualenv:
+ ``pip install git+https://bitbucket.org/pypy/numpy.git``;
+ or by directly doing
+ ``git clone https://bitbucket.org/pypy/numpy.git``,
+ ``cd numpy``, ``python setup.py install``.
+
+* non-inlined calls have less overhead
+
+* Things that use ``sys.set_trace`` are now JITted (like coverage)
+
+* JSON encoding used to be very fast, now decoding is as well
+
+* various buffer copying methods experience speedups (like list-of-ints to
+ ``int[]`` buffer from cffi)
+
+* We finally wrote (hopefully) all the missing ``os.xxx()`` functions,
+ including ``os.startfile()`` on Windows and a handful of rare ones
+ on Posix.
+
+* numpy has a rudimentary C API that cooperates with ``cpyext``
+
+Cheers,
+Armin Rigo and Maciej Fijalkowski

+.. startrev: 4cd1bc8b3111
-.. branch: sanitise_bytecode_dispatch
-Make PyPy's bytecode dispatcher easy to read, and less reliant on RPython
-magic. There is no functional change, though the removal of dead code leads
-to many fewer tests to execute.
-
-.. branch: fastjson
-Fast json decoder written in RPython, about 3-4x faster than the pure Python
-decoder which comes with the stdlib
-
-.. branch: improve-str2charp
-Improve the performance of I/O writing up to 15% by using memcpy instead of
-copying char-by-char in str2charp and get_nonmovingbuffer
-
-.. branch: flowoperators
-Simplify rpython/flowspace/ code by using more metaprogramming. Create
-SpaceOperator class to gather static information about flow graph operations.
-
-.. branch: package-tk
-Adapt package.py script to compile CFFI tk extension. Add a --without-tk switch
-to optionally skip it.
-
-.. branch: distutils-cppldflags
-Copy CPython's implementation of customize_compiler, dont call split on
-environment variables, honour CFLAGS, CPPFLAGS, LDSHARED and LDFLAGS on Unices.
-
-.. branch: precise-instantiate
-When an RPython class is instantiated via an indirect call (that is, which
-class is being instantiated isn't known precisely) allow the optimizer to have
-more precise information about which functions can be called. Needed for Topaz.
-
-.. branch: ssl_moving_write_buffer
-
-.. branch: pythoninspect-fix
-Make PyPy respect PYTHONINSPECT variable set via os.putenv in the same process
-to start interactive prompt when the script execution finishes. This adds
-new __pypy__.os.real_getenv call that bypasses Python cache and looksup env
-in the underlying OS. Translatorshell now works on PyPy.
-
-.. branch: add-statvfs
-Added os.statvfs and os.fstatvfs
-
-.. branch: statvfs_tests
-Added some addition tests for statvfs.
-
-.. branch: ndarray-subtype
-Allow subclassing ndarray, i.e. matrix
-
-.. branch: ndarray-sort
-Implement ndarray in-place sorting (for numeric types, no non-native byte
order)
-
-.. branch: pypy-pyarray
-Implement much of numpy's c api in cpyext, allows (slow) access to ndarray
-from c
-
-.. branch: kill-ootype
-
-.. branch: fast-slowpath
-Added an abstraction for functions with a fast and slow path in the JIT. This
-speeds up list.append() and list.pop().
-
-.. branch: curses_fixes
-
-.. branch: foldable-getarrayitem-indexerror
-Constant-fold reading out of constant tuples in PyPy.
-
-.. branch: mro-reorder-numpypy-str
-No longer delegate numpy string_ methods to space.StringObject, in numpy
-this works by kind of by accident. Support for merging the refactor-str-types
-branch
-
-.. branch: kill-typesystem
-Remove the "type system" abstraction, now that there is only ever one kind of
-type system used.
-
-.. branch: kill-gen-store-back-in
-Kills gen_store_back_in_virtualizable - should improve non-inlined calls by
-a bit
-
-.. branch: dotviewer-linewidth
-.. branch: reflex-support
-.. branch: numpypy-inplace-op
-.. branch: rewritten-loop-logging
-.. branch: no-release-gil
-.. branch: safe-win-mmap
-.. branch: boolean-indexing-cleanup
-.. branch: cpyext-best_base
-.. branch: cpyext-int
-.. branch: fileops2
-
-.. branch: nobold-backtrace
-Work on improving UnionError messages and stack trace displays.
-
-.. branch: improve-errors-again
-More improvements and refactorings of error messages.
-
-.. branch: improve-errors-again2
-Unbreak tests in rlib.
-
-.. branch: less-stringly-ops
-Use subclasses of SpaceOperation instead of SpaceOperator objects.
-Random cleanups in flowspace.
-
-.. branch: file-support-in-rpython
-make open() and friends rpython
-
-.. branch: incremental-gc
-Added the new incminimark GC which performs GC in incremental steps
-
-.. branch: fast_cffi_list_init
-fastpath for cffi.new("long[]")
-
-.. branch: remove-eval-frame
-remove a pointless abstraction
-
-.. branch: jit-settrace
-Allow the jit to continue running when sys.settrace() is active, necessary to
-make coverage.py fast
-
-.. branch: remove-numpypy
-Remove lib_pypy/numpypy in favor of external numpy fork
-
-.. branch: jit-counter
-Tweak the jit counters: decay them at minor collection (actually
-only every 32 minor collection is enough). Should avoid the "memory
-leaks" observed in long-running processes, actually created by the
-jit compiling more and more rarely executed paths.
-
-.. branch: fix-trace-jit
-Fixed the usage of sys.settrace() with the JIT. Also made it so using
-sys.settrace() doesn't cause the GIL to be released on every single iteration.
-
-.. branch: rordereddict
-Implement OrderedDict in RPython
