# This is a beta preview of Python 3.8 Python 3.8 is still in development. This release, 3.8.0b4 is the last of four planned beta release previews. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. # Call to action We **strongly encourage** maintainers of third-party. --------------------------------------------------------------------------------Fedora Update Notification FEDORA-2019-d11594bf0a 2019-09-14 16:29:06.039466 --------------------------------------------------------------------------------Name : python38 Product : Fedora 31 Version : 3.8.0~b4 Release : 1.fc31 URL : https://www.python.org/ Summary : Version 3.8 of the Python interpreter Description : Python 3.8 package for developers. This package exists to allow developers to test their code against a newer version of Python. This is not a full Python stack and if you wish to run your applications with Python 3.8, update your Fedora to a newer version once Python 3.8 is stable. --------------------------------------------------------------------------------Update Information: # This is a beta preview of Python 3.8 Python 3.8 is still in development. This release, 3.8.0b4 is the last of four planned beta release previews. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. # Call to action We **strongly encourage** maintainers of third-party Python projects to **test with 3.8** during the beta phase and report issues found to [the Python bug tracker](https://bugs.python.org) as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2019-09-30). Our goal is have noABI changes after beta 3 and no code changes after 3.8.0rc1, the release candidate. To achieve that, it will be extremely important to get as much exposure for 3.8 as possible during the beta phase. Please keep in mind that this is a preview release and its use is **not** recommended for production environments. # Major new features of the 3.8 series, compared to 3.7 Some of the new major new features and changes in Python 3.8 are: * [PEP 572](https://peps.python.org/pep-0572/), Assignment expressions * [PEP 570](https://peps.python.org/pep-0570/), Positional-only arguments * [PEP 587](https://peps.python.org/pep-0587/), Python Initialization Configuration (improved embedding) * [PEP 590](https://peps.python.org/pep-0590/), Vectorcall: a fast calling protocol for CPython * [PEP 578](https://peps.python.org/pep-0578/), Runtime audit hooks * [PEP 574](https://peps.python.org/pep-0574/), Pickle protocol 5 with out-of-band data * Typing-related: [PEP 591](https://peps.python.org/pep-0591/) (Final qualifier), [PEP 586](https://peps.python.org/pep-0586/) (Literal types), and [PEP 589](https://peps.python.org/pep-0589/) (TypedDict) * Parallel filesystem cache for compiled bytecode * Debug builds share ABI as release builds * f-strings support a handy `=` specifier for debugging * `continue` is now legal in `finally:` blocks * on Windows, the default `asyncio` event loop is now `ProactorEventLoop` * on macOS, the _spawn_ start method is now used by default in `multiprocessing` * `multiprocessing` can now use shared memory segments to avoid pickling costs between processes * `typed_ast` is merged back to CPython * `LOAD_GLOBAL` is now 40% faster * `pickle` now uses Protocol 4 by default, improving performance There are many other interesting changes, please consult the "What's New" page in the documentation for a full list.
