* Add os.add_dll_directory()
* Add memfd_create() and flags
* Add type annotation to flags
* Add stat_result.st_reparse_tag and flags
* Add ncurses_version
* Add Path.link_to()
* Add Picker.reducer_override()
* Add plistlib.UID
* Add has_dualstack_ipv6() and create_server()
* Add shlex.join()
* Add SSL methods and fields
* Add Python 3.8 statistics functions and classes
* Remove obsolete sys.subversion
* Add sys.unraisablehook
* Add threading.excepthook
* Add get_native_id() and Thread.native_id
* Add Python 3.8 tkinter methods
* Add CLOCK_UPTIME_RAW
* Add SupportsIndex
* Add typing.get_origin() and get_args()
* Add unicodedata.is_normalized
* Add unittest.mock.AsyncMock
Currently this is just an alias for Any like Mock and MagicMock. All of
these classes should probably be sub-classing Any and add their own
methods. See also #3224.
* Add unittest cleanup methods
* Add IsolatedAsyncioTestCase
* Add ElementTree.canonicalize() and C14NWriterTarget
* cProfile.Profile can be used as a context manager
* Add asyncio task name handling
* mmap.flush() now always returns None
* Add posonlyargcount to CodeType
While it may eventually be useful to mark the exceptions that can be
raised from a function or method, the semantics are currently undefined
and unclear.
This is a continuation of #3291, which was the initial fix for #3201.
The 2-arg version of iter() turns a callable into an iterator. The
changes made in #3291 introduce an Any return type for both the
callable's return type and the iterator's type, while in reality the
return type of the function is always the same as the iterator's type.
PR #3269 added some version checks for the argument type to setLevel
and the existence of NullHandler. While these features weren't present
in early versions of Python 3, they *are* present in Python 2.7, which
leads to false positives.
Modified __add__ method in tuple class to allow it to accept tuples with different generic parameter types. This allows, for example:
a = (1, )
b = a + (2.4, )
The function `threading.setprofile` can be called with a `None` value to
clear the profile function. This does unset the function from the
existing threads, it only clears the callback function so that new
threads are created without the profiling hook installed.
