The time has come for Python 3.8.0b1:
https://www.python.org/downloads/release/python-380b1/ =
<https://www.python.org/downloads/release/python-380b1/>
This release is the first 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 3.8.0b2, currently scheduled for 2019-07-01.


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.


A new challenger has appeared!

With the release of Python 3.8.0b1, development started on Python 3.9. =
The =E2=80=9Cmaster=E2=80=9D branch in the cpython repository now tracks =
development of 3.9 while Python 3.8 received its own branch, called =
simply =E2=80=9C3.8=E2=80=9D.


Acknowledgments

As you might expect, creating new branches triggers a lot of changes in =
configuration for all sorts of tooling that we=E2=80=99re using. =
Additionally, the inevitable deadline for new features caused a flurry =
of activity that tested the buildbots to the max. The revert hammer got  =
used more than once.

I would not be able to make this release available alone. Many thanks to =
the fearless duo of Pablo Galindo Salgado and Victor Stinner for =
spending tens of hours during the past week working on getting the =
buildbots green for release. Seriously, that took a lot of effort. We =
are all so lucky to have you both.

Thanks to Andrew Svetlov for his swift fixes to asyncio and to Yury =
Selivanov for code reviews, even when jetlagged. Thanks to Julien Palard =
for untangling the documentation configs. Thank you to Zachary Ware for =
help with buildbot and CI configuration. Thanks to Mariatta for helping =
with the bots. Thank you to Steve Dower for delivering the Windows =
installers.

Most importantly though, huge thanks to Ned Deily who not only helped me =
understand the scope of this special release but also did some of the =
grunt work involved.

Last but not least, thanks to you for making this release more meaty =
than I expected. There=E2=80=99s plenty of super exciting changes in =
there. Just take a look at =E2=80=9CWhat=E2=80=99s New =
<https://docs.python.org/3.8/whatsnew/3.8.html>=E2=80=9D!


One more thing

Hey, fellow Core Developer, Beta 2 is in four weeks. If your important =
new feature got reverted last minute, or you decided not to merge due to =
inadequate time, I have a one time offer for you (restrictions apply). =
If you:

find a second core developer champion for your change; and
in tandem you finish your change complete with tests and documentation =
before Beta 2
then I will let it in. I=E2=80=99m asking for a champion because it=E2=80=99=
s too late now for changes with hasty design or code review. And as I =
said, restrictions apply. For instance, at this point changes to =
existing APIs are unlikely to be accepted. Don=E2=80=99t start new work =
with 3.8 in mind. 3.9 is going to come sooner than you think!
