gh-143054: Disallow non-top-level Cut for now (GH-143622)
...
The behaviour of Cut in nested parentheses, Repeat, Opt, and similar
is somewhat chaotic. Apparently even the academic papers on PEG aren't
as clear as they could be.
And it doesn't really matter. Python only uses top-level cuts.
When that changes, we can clarify as much as necessary (and even
change the implementation to make sense for what we'll need).
Document that this is deliberately unspecified, and add a test to
make sure any decision is deliberate, tested and documented.

gh-143706: Fix sys.argv not set during multiprocessing forkserver __main__ preload ( #143717 )
...
The forkserver was not passing sys.argv to its main() function, causing
sys.argv to be empty during `__main__` module import in child processes. This
fixes a non-obvious regression inadvertently introduced by the gh-126631 main
preloading fix.

Bump automatic certificate update on Windows during builds (GH-143741)
...
Without this, OpenSSL that we use to download external dependencies might use a stale certificate store and be unable to connect to servers. We need to use a Windows-specific HTTP client that uses CryptoAPI directly to trigger certificate updates.
We only do it on failure to avoid hitting servers twice. And we only do it once per each URL.

gh-140795: Remove 'exc' field in SSLObject (gh-143491)

The 'exc' field was used by our debug SSL callbacks. Keep the exception
in the normal per-thread state to avoid shared mutable state between
threads.
This also avoids a reference count leak if the Python callback raised an
exception because it can be called multiple times per SSL operation.
