7.3.5 rc3 tarballs are up

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_advanced.html#checksums 


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)
