==========================
What's new in PyPy2.7 5.8+
==========================
.. this is a revision shortly after release-pypy2.7-v5.7.0
.. startrev: 44f31f6dd39f
Add cpyext interfaces for ``PyModule_New``
Correctly handle `dict.pop`` where the ``pop``
key is not the same type as the ``dict``'s and ``pop``
is called with a default (will be part of release 5.7.1)
.. branch: issue2522
Fix missing tp_new on w_object called through multiple inheritance
(will be part of release 5.7.1)
.. branch: lstrip_to_empty_string
.. branch: vmprof-native
PyPy support to profile native frames in vmprof.
.. branch: reusing-r11
.. branch: branch-prediction
Performance tweaks in the x86 JIT-generated machine code: rarely taken
blocks are moved off-line. Also, the temporary register used to contain
large constants is reused across instructions.
.. branch: vmprof-0.4.4
.. branch: controller-refactor
Refactor rpython.rtyper.controllerentry.
.. branch: PyBuffer-backport
Internal refactoring of buffers and memoryviews. Memoryviews will now be
accepted in a few more places, e.g. in compile().
.. branch: sthalik/fix-signed-integer-sizes-1494493539409
.. branch: cpyext-obj-stealing
Redo much of the refcount semantics in PyList_{SG}etItem to closer match
CPython and ensure the same PyObject stored in the list can be later
retrieved
.. branch: cpyext-recursionlimit
Implement Py_EnterRecursiveCall and associated functions
.. branch: pypy_ctypes_nosegfault_nofastpath
Remove faulty fastpath from ctypes
.. branch: sockopt_zero
Passing a buffersize of 0 to socket.getsockopt
.. branch: better-test-whatsnew
.. branch: faster-rstruct-2
Improve the performance of struct.pack and struct.pack_into by using raw_store
or gc_store_indexed whenever possible. Moreover, enable the existing
struct.unpack fast path to all the existing buffer types, whereas previously
it was enabled only for strings
.. branch: Kounavi/fix-typo-depricate-to-deprecate-p-1495624547235
.. branch: PyPy_profopt_enabled
Add profile-based optimization option ``profopt``, and specify training data
via ``profoptpath``
