bpo-45383: Get metaclass from bases in PyType_From* (GH-28748)
This checks the bases of of a type created using the FromSpec
API to inherit the bases metaclasses. The metaclass's alloc
function will be called as is done in `tp_new` for classes
created in Python.

gh-90494: Reject 6th element of the __reduce__() tuple (GH-93609)
copy.copy() and copy.deepcopy() now always raise a TypeError if
__reduce__() returns a tuple with length 6 instead of silently ignore
the 6th item or produce incorrect result.

gh-87961: Remove outdated notes from functions that aren't in the Limited API (GH-93581)
* Remove outdated notes from functions that aren't in the Limited API
Nowadays everything that *is* in the Limited API has a note added
automatically.
These notes could mislead people to think that these functions
could never be added to the limited API. Remove them.

gh-93584: Make all install+tests targets depends on all (GH-93589)
All install targets use the "all" target as synchronization point to
prevent race conditions with PGO builds. PGO builds use recursive make,
which can lead to two parallel `./python setup.py build` processes that
step on each others toes.
"test" targets now correctly compile PGO build in a clean repo.

Fix `PurePath.relative_to` links in the pathlib documentation. (GH-93268)
These are currently broken as they refer to :meth:`Path.relative_to` rather than :meth:`PurePath.relative_to`, and `relative_to` is a method on `PurePath`.

gh-79096: Protect cookie file created by {LWP,Mozilla}CookieJar.save() (GH-93463)
Note: This change is not effective on Microsoft Windows.
Cookies can store sensitive information and should therefore be protected
against unauthorized third parties. This is also described in issue #79096.
The filesystem permissions are currently set to 644, everyone can read the
file. This commit changes the permissions to 600, only the creater of the file
can read and modify it. This improves security, because it reduces the attack
surface. Now the attacker needs control of the user that created the cookie or
a ways to circumvent the filesystems permissions.
This change is backwards incompatible. Systems that rely on world-readable
cookies will breake. However, one could argue that those are misconfigured in
the first place.
gh-89973: Fix re.error in the fnmatch module. (GH-93072)
Character ranges with upper bound less that lower bound (e.g. [c-a])
are now interpreted as empty ranges, for compatibility with other glob
pattern implementations. Previously it was re.error.
gh-93442: Make C++ version of _Py_CAST work with 0/NULL. (#93500)
Add C++ overloads for _Py_CAST_impl() to handle 0/NULL. This will allow
C++ extensions that pass 0 or NULL to macros using _Py_CAST() to
continue to compile. Without this, you get an error like:
invalid ‘static_cast’ from type ‘int’ to type ‘_object*’
The modern way to use a NULL value in C++ is to use nullptr. However,
we want to not break extensions that do things the old way.

gh-93156 - fix negative indexing into absolute `pathlib.PurePath().parents` (GH-93273)
When a `_PathParents` object has a drive or a root, the length of the
object is *one less* than than the length of `self._parts`, which resulted
in an off-by-one error when `path.parents[-n]` was fed through to
`self._parts[:-n - 1]`. In particular, `path.parents[-1]` was a malformed
path object with spooky properties.
This is addressed by adding `len(self)` to negative indices.

📝 Make sure the phrase "constant-time compare" actually appears in the docs (GH-93396)
This is purely for SEO as this is the actual generic name for this kind of method and it currently does not appear in a Google search for "python constant time compare". Not creating an issue or setting this up for backports as its trivial (I think) and not a functional change.
"The Warnings Filter" section of the warnings module documentation
describes the message and module filters as "a string containing a
regular expression". While that is true when they are arguments to the
filterwarnings function, it is not true when they appear in -W or
$PYTHONWARNINGS where they are matched literally (after stripping any
starting/ending whitespace). Update the documentation to note when they
are matched literally. Also clarify that module matches the
"fully-qualified module name", rather than "module name" which is
ambiguous.

* bpo-42272: remove bad submodule warning filter doc
The `error:::mymodule[.*]` example in the "Describing Warning Filters"
section of the warnings module documentation does not behave as the
comment describes. Since the module portion of the filter string is
interpreted literally, it would match a module with a fully-qualified
name that is literally `mymodule[.*]`.
Unfortunately, there is not a way to match '"module" and any subpackages
of "mymodule"' as documented, since the module part of a filter string
is matched literally. Instead, update the filter and comment to match
only "mymodule".
