* [3.13] gh-143698: correctly check `scheduler` and `setpgroup` values for `os.posix_spawn[p]` (GH-143699)
Fix an issue where passing invalid arguments to `os.posix_spawn[p]` functions
raised a SystemError instead of a TypeError, and allow to explicitly use `None`
for `scheduler` and `setpgroup` as specified in the docs.

gh-144694: Fix re.Match.group() doc claiming [1..99] range limit (GH-144696)
The documentation incorrectly stated that numeric group arguments
must be in the range [1..99]. This limit was removed in Python 3.5
(bpo-22437). Replace with "a positive integer" since the next
sentence already documents the IndexError for out-of-range values.

gh-144833: Fix use-after-free in SSL module when SSL_new() fails (GH-144843)
In newPySSLSocket(), when SSL_new() returns NULL, Py_DECREF(self)
was called before _setSSLError(get_state_ctx(self), ...), causing
a use-after-free. Additionally, get_state_ctx() was called with
self (PySSLSocket*) instead of sslctx (PySSLContext*), which is
a type confusion bug.
Fix by calling _setSSLError() before Py_DECREF() and using
sslctx instead of self for get_state_ctx().

gh-143650: Fix importlib race condition on import failure (GH-143651)
Fix a race condition where a thread could receive a partially-initialized
module when another thread's import fails. The race occurs when:
1. Thread 1 starts importing, adds module to sys.modules
2. Thread 2 sees the module in sys.modules via the fast path
3. Thread 1's import fails, removes module from sys.modules
4. Thread 2 returns a stale module reference not in sys.modules
The fix adds verification after the "skip lock" optimization in both Python
and C code paths to check if the module is still in sys.modules. If the
module was removed (due to import failure), we retry the import so the
caller receives the actual exception from the import failure rather than
a stale module reference.
