Added str.removeprefix and str.removesuffix methods and corresponding
bytes, bytearray, and collections.UserString methods to remove affixes
from a string if present. See PEP 616 for a full description.
The constant values of future flags in the __future__ module
is updated in order to prevent collision with compiler flags.
Previously PyCF_ALLOW_TOP_LEVEL_AWAIT was clashing
with CO_FUTURE_DIVISION.
Fix the Windows implementation of os.waitpid() for exit code
larger than "INT_MAX >> 8". The exit status is now interpreted as an
unsigned number.
os.waitstatus_to_exitcode() now accepts wait status larger than
INT_MAX.
Previously, python.org macOS installers did not alter the Current version
symlink in /Library/Frameworks/Python.framework/Versions when installing
a version of Python 3.x, only when installing 2.x. Now that Python 2 is
retired, it's time to change that. This should make it a bit easier
to embed Python 3 into other macOS applications.
It is possible to use either '-isysroot /some/path' (with a space) or
'-isysroot/some/path' (no space in between). Support both forms in
places where special handling of -isysroot is done, rather than just
the first form.

* Add underscores to long numbers to improve readability
* Use bigger dataset in the bootstrapping example
* Convert single-server queue example to more useful multi-server queue
Avoid linear runtime of ShareableList.__getitem__ and
ShareableList.__setitem__ by storing running allocated bytes in
ShareableList._allocated_bytes instead of the number of bytes for
a particular stored item.

Fixes Issue39285
The example incorrectly returned True for match.
Furthermore the example is ambiguous in its usage of PureWindowsPath.
Windows is case-insensitve, however the underlying match functionality
utilizes fnmatch.fnmatchcase.

* Use ast module to find class definition
* Add NEWS entry
* Fix class with multiple children and move decorator code to the method
* Fix PR comments
1. Use node.decorator_list to select decorators
2. Remove unwanted variables in ClassVisitor
3. Simplify stack management as per review
* Add test for nested functions and async calls
* Fix pydoc test since comments are returned now correctly
* Set event loop policy as None to fix environment related change
* Refactor visit_AsyncFunctionDef and tests
* Refactor to use local variables and fix tests
* Add patch attribution
* Use self.addCleanup for asyncio
* Rename ClassVisitor to ClassFinder and fix asyncio cleanup
* Return first class inside conditional in case of multiple definitions. Remove decorator for class source.
* Add docstring to make the test correct
* Modify NEWS entry regarding decorators
* Return decorators too for bpo-15856
* Move ast and the class source code to top. Use proper Exception.
The uname binary on Android does not support -p [1]. Here is a sample

* Replace PY_INT64_T with int64_t
* Replace PY_UINT32_T with uint32_t
* Replace PY_UINT64_T with uint64_t
sha3module.c no longer checks if PY_UINT64_T is defined since it's
always defined and uint64_t is always available on platforms
supported by Python.
Add random.randbytes() function and random.Random.randbytes()
method to generate random bytes.
Modify secrets.token_bytes() to use SystemRandom.randbytes()
rather than calling directly os.urandom().
Rename also genrand_int32() to genrand_uint32(), since it returns an
unsigned 32-bit integer, not a signed integer.
The _random module is now built with Py_BUILD_CORE_MODULE defined.
Add a new internal pycore_byteswap.h header file with the following
functions:
* _Py_bswap16()
* _Py_bswap32()
* _Py_bswap64()
Use these functions in _ctypes, sha256 and sha512 modules,
and also use in the UTF-32 encoder.
sha256, sha512 and _ctypes modules are now built with the internal
C API.
