=======================================================================
PyPy v7.3.13: release of python 2.7, 3.9, and 3.10, released 2023-09-29
=======================================================================
The PyPy team is proud to release version 7.3.13 of PyPy.
This is primarily a security/bug-fix release. CPython released security
patches, and this release also improves the ability to use type
specifications via ``PyType_FromSpec`` and friends. There are also some
small speed-ups.
The release includes three different interpreters:
- PyPy2.7, which is an interpreter supporting the syntax and the features of
Python 2.7 including the stdlib for CPython 2.7.18+ (the ``+`` is for
backported security updates)
- PyPy3.9, which is an interpreter supporting the syntax and the features of
Python 3.9, including the stdlib for CPython 3.9.18.
- PyPy3.10, which is an interpreter supporting the syntax and the features of
Python 3.10, including the stdlib for CPython 3.10.13. Note it requires at
least cython 0.29.35 or cython 3.0.0b3.
The interpreters are based on much the same codebase, thus the multiple
release. This is a micro release, all APIs are compatible with the other 7.3
releases. It follows after 7.3.12 release on June 16, 2023.
We recommend updating. You can find links to download the v7.3.13 releases here:
https://pypy.org/download.html
We would like to thank our donors for the continued support of the PyPy
project. If PyPy is not quite good enough for your needs, we are available for
`direct consulting`_ work. If PyPy is helping you out, we would love to hear about
it and encourage submissions to our blog_ via a pull request
to https://github.com/pypy/pypy.org
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: bug fixes,
`PyPy`_ and `RPython`_ documentation improvements, or general `help`_ with making
RPython's JIT even better.
If you are a python library maintainer and use C-extensions, please consider
making a HPy_ / CFFI_ / cppyy_ version of your library that would be performant
on PyPy. In any case, both `cibuildwheel`_ and the `multibuild system`_ support
building wheels for PyPy.

What is PyPy?
=============
PyPy is a Python interpreter, a drop-in replacement for CPython
It's fast (`PyPy and CPython 3.7.4`_ 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.
We provide binary builds for:
* **x86** machines on most common operating systems
(Linux 32/64 bits, Mac OS 64 bits, Windows 64 bits)
* 64-bit **ARM** machines running Linux (``aarch64``).
* Apple **M1 arm64** machines (``macos_arm64``).
* **s390x** running Linux
PyPy support Windows 32-bit, Linux PPC64 big- and little-endian, and Linux ARM
32 bit, but does not release binaries. Please reach out to us if you wish to
sponsor binary releases for those platforms. Downstream packagers provide
binary builds for debian, Fedora, conda, OpenBSD, FreeBSD, Gentoo, and more.

Changelog
=========
For all versions
----------------
- Update to ssl 1.1.1w, or 3.0.10 when embedding libraries for a portable build
Bugfixes
~~~~~~~~
- Report exceptions that are created when forcing an oefmt as unraisable (issue
3978_)
Speedups and enhancements
~~~~~~~~~~~~~~~~~~~~~~~~~
- Shrink the size of the PyPy binaries by about ~700KiB by auto-generating
fewer versions of the RPython dict and list types.
- Speed up tracing and code generation in the JIT slightly by reducing the size
in memory of one of its central data structures, the ``MIFrame``. This is
done by not allocating three lists of length 256 for the registers in the
MIFrames and the blackhole frames. Almost all jitcodes have much smaller
frame sizes.
- Improve ``str.strip()`` to make it better optimizable by the JIT.
- Make access to ``sys.flags`` faster by making sure the JIT can constant-fold
the access most of the time. (especially important on py3.x, where every
``bytes.decode`` call checks ``sys.flags.utf8_mode``)
- Speed up the flowspace a lot for huge functions. This makes building the PyPy
binary a little bit faster.
- Make ``UnicodeIO`` store its data in a list of ``r_int32``, as opposed to
using the rpython (Python2.7) unicode type. we want to get rid of the unicode
type and also it requires an extra copy all the time.
- Make every Python integer that doesn't fit into a machine word use one word
less memory by storing the sign differently.
Python 3.9+
-----------
- Create c-extension modules used in tests as part of the build (in
package.py), not as part of testing.
Bugfixes
~~~~~~~~
- More selectively clear ``StopIteration`` exceptions on ``tp_iternext`` (issue
3956_). Diagnosed and fixed by a new contributor.
- Copy less when creating a venv by using a ``PYPY_PORTABLE_DEPS.txt`` file to
state which dlls to copy in a portable build (issue 3611_)
- On macos ``sendfile`` can return an error while sending part of the file
(issue 3964_)
- Fixes on both app-level and C level for ``Py_TPFLAGS_BASETYPE=0`` (issue
2742_). Also set ``PyType_Type.tp_itemsize`` to ``sizeof(PyMemberDef)`` like
on CPython
- Fix ``PyType_FromSpecWithBases`` to correctly use ``Py_tp_doc``,
``Py_tp_members`` in spec, fix ``__module__`` assignment, better handle
``__name__`` and ``tp_name``
- Hide ``functools`` wrappers from the stack when reporting warnings (issue
3988_)
- Fix edge case of datetime isoformat parsing (issue 3989_)
- Accept NULL ``tp_doc`` (bpo-41832_)
- Align ``nb_int`` with ``PyNumber_Long`` (to get consistent error messages)
- Handle ``pathlib.Path`` objects in ``_ssl`` (issue 4002_)
- Implement ``_PyLong_AsInt`` which is not part of the stable API but used in
testing
Speedups and enhancements
~~~~~~~~~~~~~~~~~~~~~~~~~
- Avoid compiling a new regex where not needed (in ``email``, ``csv``, and
elsewhere) (issue 3961_)
Python 3.10
-----------
Bugfixes
~~~~~~~~
- Fix, test locking in HMAC update (issue 3962_)
- When re-assigning to ``type.__bases__``, rebuild the cpyext type struct
(issue 3976_)
- Add missing slot macro ``Py_am_send`` (issue 3990_)
