I have uploaded rc3 candidates to https://downloads.python.org/pypy/ and the checksums can be found in the PR to pypy.org https://608f07a183d23c00083f6115--keen-mestorf-442210.netlify.app/download_a... The changes are in the release note. https://doc.pypy.org/en/latest/release-v7.3.5.html: - The new windows 64-bit builds improperly named c-extension modules with the same extension as the 32-bit build (issue 3443) - Use the windows-specific PC/pyconfig.h rather than the posix one - A change to the python 3.7 sysconfig.get_config_var('LIBDIR') was wrong, leading to problems finding libpypy3-c.so for embedded PyPy (issue 3442). - Instantiate distutils.command.install schema for PyPy-specific implementation_lower - Four upstream (CPython) security patches were applied - When assigning the full slice of a list, evaluate the rhs before clearing the list (issue 3440) - On Python2, PyUnicode_Contains accepts bytes as well as unicode. - Update the packaged sqlite3 to 3.35.5 on windows. While not a bugfix, this seems like an easy win. Added in this rc3: ----------------------- - Fix the return type for |_Py_HashDouble| which impacts 64-bit windows - Delay thread-checking logic in greenlets until the thread is actually started (continuation of issue 3441 <https://foss.heptapod.net/pypy/pypy/-/issues/3441>) - Fix for json-specialized dicts (issue 3460 <https://foss.heptapod.net/pypy/pypy/-/issues/3460>) - Specialize |ByteBuffer.setslice| which speeds up binary file reading by a factor of 3 - Test and fix a broken code path in _sqlite3 (issue 3432) Please try them out Matti
