Python 3.8.4 is released. Here is how to install Python 3.8.4 in Ubuntu Linux. Python 3.8.4 is the newest major release of the Python programming language, and it contains many new features and optimizations.
Python 3.8.4
The Python Package Index (PyPI) hosts thousands of third-party modules for Python. Both Python’s standard library and the community-contributed modules allow for endless possibilities.
Python is developed under an OSI-approved open source license, making it freely usable and distributable, even for commercial use.
Major new features of the 3.8 series, compared to 3.7
Security
- bpo-41162: Audit hooks are now cleared later during finalization to avoid missing events.
- bpo-29778: Ensure
python3.dllis loaded from correct locations when Python is embedded (CVE-2020-15523).
Core and Builtins
- bpo-41247: Always cache the running loop holder when running
asyncio.set_running_loop. - bpo-41252: Fix incorrect refcounting in _ssl.c’s
_servername_callback(). - bpo-41218: Python 3.8.3 had a regression where compiling with ast.PyCF_ALLOW_TOP_LEVEL_AWAIT would aggressively mark list comprehension with CO_COROUTINE. Now only list comprehension making use of async/await will tagged as so.
- bpo-41175: Guard against a NULL pointer dereference within bytearrayobject triggered by the
bytearray() + bytearray()operation. - bpo-39960: The “hackcheck” that prevents sneaking around a type’s __setattr__() by calling the superclass method was rewritten to allow C implemented heap types.
Library
- bpo-41235: Fix the error handling in
ssl.SSLContext.load_dh_params(). - bpo-41193: The
write_history()atexit function of the readline completer now ignores anyOSErrorto ignore error if the filesystem is read-only, instead of only ignoringFileNotFoundErrorandPermissionError. - bpo-41043: Fixed the use of
glob()in the stdlib: literal part of the path is now always correctly escaped. - bpo-39384: Fixed email.contentmanager to allow set_content() to set a null string.
IDLE
- bpo-37765: Add keywords to module name completion list. Rewrite Completions section of IDLE doc.
- bpo-41152: The encoding of
stdin,stdoutandstderrin IDLE is now always UTF-8.
