+=====================================
+PyPy2.7 and PyPy3.5 v5.9 dual release
+=====================================
+
+The PyPy team is proud to release both PyPy2.7 v5.9 (an interpreter supporting
+Python 2.7 syntax), and a beta-quality PyPy3.5 v5.9 (an interpreter for Python
+3.5 syntax). The two releases are both based on much the same codebase, thus
+the dual release. Note that PyPy3.5 supports Linux 64bit only for now.
+
+This new PyPy2.7 release includes the upstream stdlib version 2.7.13, and
+PyPy3.5 includes the upstream stdlib version 3.5.3.
+
+NumPy and Pandas now work on PyPy2.7. Issues that appeared as excessive memory
+use were cleared up and other incompatibilities were resolved. The C-API
+compatibility layer does slow down code which crosses the python-c interface
+often, we have ideas on how it could be improved, and still recommend
+using pure python on PyPy or interfacing via CFFI_. Many other modules
+based on C-API exentions now work on PyPy as well.
+
+Cython 0.27 (released last week) should support more projects with PyPy, both
+on PyPy2.7 and PyPy3.5 beta.
+
+We optimized the JSON parser for recurring string keys, which should decrease
+memory use to 50% and increase parsing speed by up to 15% for large JSON files
+with many repeating dictionary keys (which is quite common).
+
+CFFI_, which is part of the PyPy release, has been updated to 1.11.1,
+improving an already great package for interfacing with C. CFFI now supports
+complex arguments in API mode, as well as ``char16_t`` and ``char32_t`` and has
+improved support for callbacks.
+
+Please let us know if your use case is slow, we have ideas how to make things
+faster but need real-world examples (not micro-benchmarks) of problematic code.
+
+Work sponsored by a Mozilla grant_ continues on PyPy3.5; numerous fixes from
+CPython were ported to PyPy. Of course the bug fixes and performance
enhancements
+mentioned above are part of both PyPy2.7 and PyPy3.5 beta.
+
+As always, this release fixed many other issues and bugs raised by the
+growing community of PyPy users. We strongly recommend updating.
+
+You can download the v5.9 releases here:
+
+ http://pypy.org/download.html
+
+We would like to thank our donors for the continued support of the PyPy
+project.
+
+We would also like to thank our contributors and
+encourage new people to join the project. PyPy has many
+layers and we need help with all of them: `PyPy`_ and `RPython`_ documentation
+improvements, tweaking popular `modules`_ to run on pypy, or general `help`_
+with making RPython's JIT even better.

+
+What is PyPy?
+=============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7 and CPython 3.5. It's fast (`PyPy and CPython 2.7.x`_ performance
comparison)
+due to its integrated tracing JIT compiler.
+
+We also welcome developers of other `dynamic languages`_ to see what RPython
+can do for them.
+
+The PyPy 2.7 release supports:
+
+ * **x86** machines on most common operating systems
+ (Linux 32/64 bits, Mac OS X 64 bits, Windows 32 bits, OpenBSD, FreeBSD)
+
+ * newer **ARM** hardware (ARMv6 or ARMv7, with VFPv3) running Linux,
+
+ * big- and little-endian variants of **PPC64** running Linux,
+
+ * **s390x** running Linux
+

+======================================================================================
+
+See also issues that were resolved_
+
+Note that these are also merged into PyPy 3.5
+
+* New features and cleanups
+
+ * Add support for ``PyFrozenSet_New``, ``PyObject_HashNotImplemented``,
+ ``PyObject_Print(NULL, ...)``, ``PyObject_RichCompareBool(a, a, ...)``,
+ ``PyType_IS_GC`` (does nothing), ``PyUnicode_FromFormat``
+ * ctypes ``char_p`` and ``unichar_p`` indexing now CPython compatible
+ * ``gcdump`` now reports largest object
+ * More complete support in the ``_curses`` CFFI module
+ * Add cPickle.Unpickler.find_global (issue 1853_)
+ * Fix ``PyErr_Fetch`` + ``PyErr_NormalizeException`` with no exception set
+ * Simplify ``gc.get_referrers()`` to return the opposite of
``gc.get_referents()``
+ * Update RevDB to version pypy2.7-v5.6.2
+ * Previously, ``instance.method`` would return always the same bound method
+ object, when gotten from the same instance (as far as ``is`` and ``id()``
+ can tell). CPython doesn't do that. Now PyPy, like CPython, returns a
+ different bound method object every time. For ``type.method``, PyPy2 still
+ returns always the same *unbound* method object; CPython does it for
built-in
+ types but not for user-defined types
+ * Link to disable PaX protection for the JIT when needed
+ * Update build instructions and an rarely used Makefile
+ * Recreate support for using leakfinder in cpyext tests which had suffered
+ bit-rot, disable due to many false positives
+ * Add more functionality to ``sysconfig``
+ * Added ``_swappedbytes_`` support for ``ctypes.Structure``
+ * Better support the ``inspect`` module on ``frames``
+
+* Bug Fixes
+
+ * Fix issue 2592_ - cpyext ``PyListObject.pop``, ``pop_end`` must return a
value
+ * Implement ``PyListOjbect.getstorage_copy``
+ * Fix for ``reversed(dictproxy)`` issue 2601_
+ * Fix for duplicate names in ctypes' ``_fields__``, issue 2621_
+ * Update built-in ``pyexpat`` module on win32 to use UTF-8 version not UTF-16
+ * ``gc.get_objects`` now handles objects with finalizers more consistently
+ * Fixed memory leak in ``SSLContext.getpeercert`` returning validated
+ certificates and ``SSLContext.get_ca_certs(binary_mode=True)``
+ (_get_crl_dp) `CPython issue 29738`_
+
+* Performance improvements:
+
+ * Improve performance of ``bytearray.extend`` by rewriting portions in
app-level
+ * Optimize list accesses with constant indexes better by retaining more
+ information about them
+ * Add a jit driver for ``array.count`` and ``array.index``
+ * Improve information retained in a bridge wrt ``array``
+ * Move some dummy CAPI functions and ``Py*_Check`` functions from RPython
into
+ pure C macros
+ * In the fast ``zip(intlist1, intlist2)`` implementation, don't wrap and
unwrap
+ all the ints
+ * Cache string keys that occur in JSON dicts, as they are likely to repeat
+
+* RPython improvements
+
+ * Do not preallocate a RPython list if we only know an upper bound on its
size
+ * Issue 2590_: fix the bounds in the GC when allocating a lot of objects
with finalizers
+ * Replace magical NOT RPYTHON comment with a decorator
+ * Implement ``socket.sendmsg()``/``.recvmsg()`` for py3.5
+ * Reduce excessive ``memory_pressure`` for ``_SSLContext`` objects and add
+ ``memory_pressure`` for ``_SSLSocket`` objects
+
+* Degredations
+
+ * Disable vmprof on win32, due to upstream changes that break the internal
``_vmprof`` module

+ * Fix for ``reversed(mapping object)`` issue 2601_
+ * Fixing regression with non-started generator receiving non-``None``, should

-What's new in PyPy2.7 5.9+
-==========================
-
-.. this is a revision shortly after release-pypy2.7-v5.8.0
-.. startrev: 558bd00b3dd8
-
-In previous versions of PyPy, ``instance.method`` would return always
-the same bound method object, when gotten out of the same instance (as
-far as ``is`` and ``id()`` can tell). CPython doesn't do that. Now
-PyPy, like CPython, returns a different bound method object every time.
-For ``type.method``, PyPy2 still returns always the same *unbound*
-method object; CPython does it for built-in types but not for
-user-defined types.
-
-.. branch: cffi-complex
-.. branch: cffi-char16-char32
-
-The two ``cffi-*`` branches are part of the upgrade to cffi 1.11.
-
-.. branch: ctypes_char_indexing
-
-Indexing into char* behaves differently than CPython
-
-.. branch: vmprof-0.4.8
-
-Improve and fix issues with vmprof
-
-.. branch: issue-2592
-
-CPyext PyListObject.pop must return the value
-
-.. branch: cpyext-hash_notimpl
-
-If ``tp_hash`` is ``PyObject_HashNotImplemented``, set
``obj.__dict__['__hash__']`` to None
-
-.. branch: cppyy-packaging
-
-Renaming of ``cppyy`` to ``_cppyy``.
-The former is now an external package installable with ``pip install cppyy``.
-
-.. branch: Enable_PGO_for_clang
-
-.. branch: nopax
-
-At the end of translation, run ``attr -q -s pax.flags -V m`` on
-PAX-enabled systems on the produced binary. This seems necessary
-because PyPy uses a JIT.
-
-.. branch: pypy_bytearray
-
-Improve ``bytearray`` performance (backported from py3.5)
-
-.. branch: gc-del-limit-growth
-
-Fix the bounds in the GC when allocating a lot of objects with finalizers,
-fixes issue #2590
-
-.. branch: arrays-force-less
-
-Small improvement to optimize list accesses with constant indexes better by
-throwing away information about them less eagerly.
-
-
-.. branch: getarrayitem-into-bridges
-
-More information is retained into a bridge: knowledge about the content of
-arrays (at fixed indices) is stored in guards (and thus available at the
-beginning of bridges). Also, some better feeding of information about known
-fields of constant objects into bridges.
-
-.. branch: cpyext-leakchecking
-
-Add support for leakfinder in cpyext tests (disabled for now, due to too many
-failures).
-
-.. branch: pypy_swappedbytes
-
-Added ``_swappedbytes_`` support for ``ctypes.Structure``
-
-.. branch: pycheck-macros
-
-Convert many Py*_Check cpyext functions into macros, like CPython.
-
-.. branch: py_ssize_t
-
-Explicitly use Py_ssize_t as the Signed type in pypy c-api

+=========================
+What's new in PyPy2.7 5.9
+=========================
+
+.. this is a revision shortly after release-pypy2.7-v5.8.0
+.. startrev: 558bd00b3dd8
+
+In previous versions of PyPy, ``instance.method`` would return always
+the same bound method object, when gotten out of the same instance (as
+far as ``is`` and ``id()`` can tell). CPython doesn't do that. Now
+PyPy, like CPython, returns a different bound method object every time.
+For ``type.method``, PyPy2 still returns always the same *unbound*
+method object; CPython does it for built-in types but not for
+user-defined types.
+
+.. branch: cffi-complex
+.. branch: cffi-char16-char32
+
+The two ``cffi-*`` branches are part of the upgrade to cffi 1.11.
+
+.. branch: ctypes_char_indexing
+
+Indexing into char* behaves differently than CPython
+
+.. branch: vmprof-0.4.8
+
+Improve and fix issues with vmprof
+
+.. branch: issue-2592
+
+CPyext PyListObject.pop must return the value
+
+.. branch: cpyext-hash_notimpl
+
+If ``tp_hash`` is ``PyObject_HashNotImplemented``, set
``obj.__dict__['__hash__']`` to None
+
+.. branch: cppyy-packaging
+
+Renaming of ``cppyy`` to ``_cppyy``.
+The former is now an external package installable with ``pip install cppyy``.
+
+.. branch: Enable_PGO_for_clang
+
+.. branch: nopax
+
+At the end of translation, run ``attr -q -s pax.flags -V m`` on
+PAX-enabled systems on the produced binary. This seems necessary
+because PyPy uses a JIT.
+
+.. branch: pypy_bytearray
+
+Improve ``bytearray`` performance (backported from py3.5)
+
+.. branch: gc-del-limit-growth
+
+Fix the bounds in the GC when allocating a lot of objects with finalizers,
+fixes issue #2590
+
+.. branch: arrays-force-less
+
+Small improvement to optimize list accesses with constant indexes better by
+throwing away information about them less eagerly.
+
+
+.. branch: getarrayitem-into-bridges
+
+More information is retained into a bridge: knowledge about the content of
+arrays (at fixed indices) is stored in guards (and thus available at the
+beginning of bridges). Also, some better feeding of information about known
+fields of constant objects into bridges.
+
+.. branch: cpyext-leakchecking
+
+Add support for leakfinder in cpyext tests (disabled for now, due to too many
+failures).
+
+.. branch: pypy_swappedbytes
+
+Added ``_swappedbytes_`` support for ``ctypes.Structure``
+
+.. branch: pycheck-macros
+
+Convert many Py*_Check cpyext functions into macros, like CPython.
+
+.. branch: py_ssize_t
+
+Explicitly use Py_ssize_t as the Signed type in pypy c-api
