Recently I received 20 one-year licenses from JetBrains for the PyCharm IDE (Professional) and other JetBrains products (the licenses cover their "All Products Pack") for use in Python development. There are 11 licenses available - of the licenses I asked for last year, nine people took them up, so those are in use and come out of the allocation of 20.
Those of you who took up the licences last time should find that the tools continue to work normally. The licences expire on 27 November 2018.
If any others of you are interested in using these licenses, let me know off-list and I will forward the license access details to you. To access the licenses, you will need to have (or create) a JetBrains account.
On behalf of the Python development community and the Python 3.7 release
team, I'm happy to announce the availability of Python 3.7.0b3. b3 is
the third of four planned beta releases of Python 3.7, the next major
release of Python, and marks the end of the feature development phase
for 3.7. You can find Python 3.7.0b3 here:
Among the new major new features in Python 3.7 are:
* PEP 538, Coercing the legacy C locale to a UTF-8 based locale
* PEP 539, A New C-API for Thread-Local Storage in CPython
* PEP 540, UTF-8 mode
* PEP 552, Deterministic pyc
* PEP 553, Built-in breakpoint()
* PEP 557, Data Classes
* PEP 560, Core support for typing module and generic types
* PEP 562, Module __getattr__ and __dir__
* PEP 563, Postponed Evaluation of Annotations
* PEP 564, Time functions with nanosecond resolution
* PEP 565, Show DeprecationWarning in __main__
* PEP 567, Context Variables
Please see "What’s New In Python 3.7" for more information.
Additional documentation for these features and for other changes
will be provided during the beta phase.
Beta releases are intended to give you the opportunity to test new
features and bug fixes and to prepare their projects to support the
new feature release. We strongly encourage you to test your projects
with 3.7 during the beta phase and report issues found to
https://bugs.python.org as soon as possible.
While the release is 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 (2018-05-21). Our goal
is have no ABI changes after beta 3 and no code changes after rc1.
To achieve that, it will be extremely important to get as much exposure
for 3.7 as possible during the beta phase.
Attention macOS users: there is a new installer variant for
macOS 10.9+ that includes a built-in version of Tcl/Tk 8.6. This
variant is expected to become the default version when 3.7.0 releases.
Check it out! We welcome your feedback. As of 3.7.0b3, the legacy
10.6+ installer also includes a built-in Tcl/Tk 8.6.
Please keep in mind that this is a preview release and its use is
not recommended for production environments.
The next planned release of Python 3.7 will be 3.7.0b4, currently
scheduled for 2018-04-30. More information about the release schedule
can be found here:
nad(a)python.org -- 
Python 3.6.5 is now available. 3.6.5 is the fifth maintenance release of
Python 3.6, which was initially released in 2016-12 to great interest.
Detailed information about the changes made in 3.6.5 can be found in its
change log. You can find Python 3.6.5 and more information here:
See the "What’s New In Python 3.6" document for more information about
features included in the 3.6 series. Detailed information about the
changes made in 3.6.5 can be found in the change log here:
Attention macOS users: as of 3.6.5, there is a new additional installer
variant for macOS 10.9+ that includes a built-in version of Tcl/Tk 8.6.
This variant is expected to become the default variant in future
releases. Check it out!
The next maintenance release is expected to follow in about 3 months,
around the end of 2018-06.
Thanks to all of the many volunteers who help make Python Development and
these releases possible! Please consider supporting our efforts by
volunteering yourself or through organization contributions to the Python
nad(a)python.org -- 
Just a reminder that 3.7.0b3 is almost upon us. Please get your
feature fixes, bug fixes, and documentation updates in before
2018-03-26 ~23:59 Anywhere on Earth (UTC-12:00). That's a little over
3.5 days from now.
IMPORTANT: We are now entering the final phases of 3.7.0. After the
tagging for 3.7.0b3, the intention is that the ABI for 3.7.0 is
frozen. After next week's 3.7.0b3, there will only be two more
opportunities planned for changes prior to 3.7.0 final:
- 2018-04-30 3.7.0 beta 4
- 2018-05-31 3.7.0 release candidate
As I've noted in previous communications, we need to start locking
down 3.7.0 so that our downstream users, that is, third-party package
developers, Python distributors, and end users, can test their code
with confidence that the actual release of 3.7.0 will hold no
unpleasant surprises. So after 3.7.0b3, you should treat the 3.7
branch as if it is already released and in maintenance mode. That
means you should only push the kinds of changes that are appropriate
for a maintenance release: non-ABI-changing bug and feature fixes and
documentation updates. If you find a problem that requires an
ABI-altering or other significant user-facing change (for example,
something likely to introduce an incompatibility with existing users'
code or require rebuilding of user extension modules), please make
sure to set the b.p.o issue to "release blocker" priority and describe
there why you feel the change is necessary. If you are reviewing PRs
for 3.7 (and please do!), be on the lookout for and flag potential
incompatibilities (we've all made them).
Thanks again for all of your hard work towards making 3.7.0 yet
another great release!

Cheryl Sabella kindly migrated a patch I'd put on bpo some time ago
but forgotten about onto github. The PR (#6158) is ready to go (I
think) but this is the first time since the migration to github that
I've done a merge, and I'm not quite sure what the workflow is :-( I
didn't see much in the devguide (which covers how to write a PR, how
to test it etc, but not so much how to merge it, unless I missed
something, or it's so simple that the little I did find is all that's
Am I right that all I need to do is hit "Squash and Merge", tidy up
the commit message, and that's it for master? This is a doc change
which should probably go into 3.7 - so I presume I just add the "Needs
backport" label and Miss Islington does the rest? (I assume doc fixes
are still OK for 3.7 at this point?)
Is there anything else I've missed? (Do I need another approver? I'm
assuming not, for a doc fix).
Sorry for the dumb questions - if I've missed a glaringly obvious
explanation, feel free to let me know. I'm just a little nervous that
it's *so* simple I feel I must have missed something!
PS Thanks to everyone who has worked on the new github workflow. What
I've done so far has been really straightforward, and if I'm right in
what I think I need to do above, then you've made the rest of the
process beautifully simple, too!

FWIW this butts up against PyCon UK 2018, which starts Saturday
September 15th and runs for five days. I suppose it's getting harder
and harder to throw a dart at a wall calendar and land on a date which
*doesn't* have a PyCon running. But still, I can think of one person

It’s that time again: time to start thinking about the Python Language
Summit! The 2018 summit will be held on Wednesday, May 9, from 10am to
4pm, at the Huntington Convention Center in Cleveland, Ohio, USA. Your
befezzled and befuddled hosts Barry and Larry will once more be behind
the big desk in front.
The summit’s purpose is to disseminate information and spark
conversation among core Python developers. It’s our yearly opportunity
to get together for an in-person discussion, to review interesting
developments of the previous year and hash out where we’re going next.
And we have lots to talk about! 3.7 is in beta, and we've all
collectively started work on 3.8 too.
As before, we’re using Google Forms to collect signups. Signups are
open now; the deadline to sign up is Wednesday April 18th, 2018 (AoE).
Please do us a favor and sign up sooner rather than later. The signup
form is simpler this year--I bet most people can be done in less than
One difference from last year: there are now *two* forms. The first
form is for signing up to attend (the "Request For Invitation" form),
and the second form is for proposing a talk. Please note: if you want
to present, you still need to fill out the Request For Invitation form
too. (Yes, it's more complicated this way, sorry. But having both on
the same form kind of enforced a one-to-one mapping, and it's really a
many-to-many mapping: one person might propose multiple talks, and one
talk might have multiple presenters. Overall this should be less
You can find links to *both* forms on the official Python Language
Summit 2018 page:
A few notes:
* There will be lightning talks! Signups will only be available
during the Language Summit itself.
* You don’t need to be registered for PyCon in order to attend the summit!
* We’ll have badge ribbons for Language Summit participants, which
we’ll hand out at the summit room in the morning.
* We're inviting Jake Edge from Linux Weekly News to attend the summit
and provide press coverage again. Jake’s done a phenomenal job of
covering the last few summits, providing valuable information not
just for summit attendees, but also for the Python community at
large. Jake’s coverage goes a long way toward demystifying the
summit, while remaining respectful of confidential information
that’s deemed “off the record” ahead of time by participants.
One big final note (please read this!):
When using Google Forms, you /can/ edit your responses later! When
you fill out the form and hit Submit, the submission complete page
(the one that says "Thanks for playing!") will have a link on it
labeled "Edit your response". BOOKMARK THIS LINK! You can use this
link at /any time/ to edit your response, up to the point that
signups close on April 18th. Keep in mind, you'll need to bookmark
each response independently: once for signing up to attend ("Request
For Invitation"), and once for each talk proposal you submit.
Again, /please/ be sure to save this bookmark yourself--we don't
know how to find the link for you later if you don't save it.
We hope to see you at the summit!
