[RELEASE] Python 3.8.0b2 is now available for testing
by Łukasz Langa 08 Jul '19

08 Jul '19

After a few days of delay, but somewhat cutely timed with the US Independence Day, I present you Python 3.8.0b2: https://www.python.org/downloads/release/python-380b2/ <https://www.python.org/downloads/release/python-380b2/> This release is the second 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. The next pre-release of Python 3.8 will be 3.8.0b3, currently scheduled for 2019-07-29. 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. No more non-bugfixes allowed on the “3.8” branch The time has come, team. Please help make Python 3.8 as stable as possible and keep all features not currently landed for Python 3.9. Don’t fret, it’ll come faster than you think. - Ł

[RELEASE] Python 3.7.4rc2 is now available for testing
by Ned Deily 02 Jul '19

02 Jul '19

Python 3.7.4rc2 is now available. 3.7.4rc2 is the second release preview of the next maintenance release of Python 3.7, the latest feature release of Python. Assuming no further critical problems are found prior to 2019-07-08, no code changes are planned between this release candidate and the final release. The release candidate is intended to give you the opportunity to test the new security and bug fixes in 3.7.4. Because of the small number of changes between rc1, the original release preview, and rc2, we are planning on an abbreviated exposure cycle so we can get the final release to you as soon as possible. We strongly encourage you to test your projects and report issues found to https://bugs.python.org/ as soon as possible. Please keep in mind that this is a preview release and, thus, is not recommended for production environments. You can find the release files, a link to the changelog, and more information here: https://www.python.org/downloads/release/python-374rc2/ -- Ned Deily nad(a)python.org -- []
