    Product     : Fedora 29
    Version     : 3.8.0~b4
    Release     : 1.fc29
    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 no ABI
    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://www.python.org/dev/peps/pep-0572/), Assignment expressions *   [PEP
    570](https://www.python.org/dev/peps/pep-0570/), Positional-only arguments *

    Runtime audit hooks *   [PEP 574](https://www.python.org/dev/peps/pep-0574),
    Pickle protocol 5 with out-of-band data *   Typing-related: [PEP

    586](https://www.python.org/dev/peps/pep-0586) (Literal types), and [PEP
    589](https://www.python.org/dev/peps/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.  The next pre-release of Python 3.8 and the first release candidate will
    be 3.8.0rc1, currently scheduled for 2019-09-30.  # More resources  *   [Online
