Description

# 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.
