Issue 359: Python 3.15 Is Here and Python 3.16 Alpha 1
News
Python 3.15.0 (final) is here!
Python 3.15 is out, with explicit lazy imports (PEP 810), built-in frozendict and sentinel types, UTF-8 as the default encoding, and a JIT that runs 7-12% faster depending on the platform. If you use IDLE or tkinter on macOS 27, read the release notes first: menu dialogs can hang.
Python 3.16.0 alpha 1 is now available
The first of seven alphas for Python 3.16 is out, with features landing until the May 4, 2027 beta and the final release planned for October 5, 2027. Library maintainers are invited to start testing now.
Django Software Foundation
Django Steering Council Meetings - 2026
Notes from the October 5 meeting with the Fellows: the set-returning DEP needs reviewers, every memcached Python client is now defunct, and Python 3.15 support raises questions about makedirs permission semantics. PyPy 8.0 support and the Sovereign Tech Fund's resilience program were also on the agenda.
Wagtail CMS News
We have a stellar group of speakers for Wagtail Space 2026
The schedule is out for this year's online, half-day Wagtail Space, opening with Thibaud Colas's State of Wagtail. Talks cover running Wagtail at scale on Kubernetes, measuring a site's web emissions, agent readiness, and Wagtail Preen, a new codemod CLI.
Updates to Django
Last week we had 26 pull requests merged into Django by 9 different contributors - including a first-time contributor! Congratulations to Abheet for having their first commits merged into Django - welcome on board!
New in Django 6.2:
- The
nowtemplate tag now supports passing a template variable as the format string.
New in Django 6.1:
- To improve accessibility, the admin's breadcrumbs are now rendered as
<li>elements within an<ol>instead of<div>elements. The breadcrumb for the current page is now marked witharia-current="page". - Added compatibility for
oracledb26.0.0+ (#37411). - Fixed a regression in Django 6.1 where the YAML serializer crashed if passed the
sort_keysoption (#37405). - Fixed a regression in Django 6.1 where a
Valueexpression with aNonevalue and an output field other thanJSONFieldcrashed on SQLite when used in a top-levelJSONFieldinlookup (#37403). Using such an expression in anINlookup is likely unintended, since SQLNULLcannot match any value.
Django Fellow Reports
Django Fellow Report - Jacob
Jacob cleared a spike of release blockers for 6.1.2, all but two of them found internally using a model, and added compatibility for python-oracledb 26. He also fixed a YAML serializer crash with sort_keys and landed prep work for multiline template tags.
Django Fellow Report - Sarah
Sarah shipped the October 6 security release (four CVEs plus a follow-up across three versions), the most complex she has done, and reviewed fixes like @non_atomic_requests now recognizing async views. Discussions about contributor sustainability mean Django may sit out next summer's GSoC.
Django Fellow Report - Natalia
Natalia confirmed a low-severity vulnerability and prepared its patch, filed two public hardening tickets (multipart boundaries and response header characters), and paused new HackerOne submissions. She also opened a PR to replace Django's vendored makedirs with os.makedirs() on Python 3.15+.

Django: set up its test suite with uv
Adam Johnson's alternative to the official contributing setup: one uv pip install -e . -r tests/requirements/py3.txt gets Django and its test requirements into a fresh virtual environment. If pylibmc won't compile, filter it out with grep -v and process substitution, and Django skips only the memcached tests.
Towards Async Transactions in Django
Transactions need ordered queries, but async tasks interleave at every await, so one task's rollback can throw away another's writes. Carlton Gibson lays out the design worked out at the Django on the Med sprints: async with transaction.atomic() gets its own worker thread and connection, with only the opening task allowed to nest. He is aiming for 6.2, and a follow-up post says the asgiref release it depends on is due at the end of October. django-filter 26.2 is also out, adding Python 3.15 and escaping LinkWidget labels by default.
Personal Replacement for Echofeed
With Echofeed winding down, Paul Traylor built his own blog-to-Mastodon pipeline on Django's new tasks framework. His django-feedparser-low package handles feed scraping with ETag and 304 support, and a feed_filter decorator ties a task to an Entry's post_save so each feed can trigger its own processing.
Django Beginners: Part 2
Andrew Miller fleshes out his django.contrib.beginners idea as "guardrails" (stricter, silenceable warnings against common foot-guns) and "scaffolds" (starting points like the registration view django.contrib.auth leaves out), in a package meant to be outgrown. He wants to build it with a group from day one and is looking for collaborators.
Django Day Copenhagen 2026 and Secrets
Efe Oge recaps the talks that stuck with him, from Tom Carrick on rate limiting to Denny on timezones, and the hallway finding behind his own signing talk: most teams hand secret management to Ansible Vault or Kubernetes rather than Django.
Iframes that finally fit their content
Chrome 154 adds frame-sizing: content-height, so an iframe grows to fit its content with one line of CSS instead of postMessage and ResizeObserver plumbing. The catch: the embedded page has to opt in with a responsive-embedded-sizing meta tag naming the origins allowed to size it.
Core Dispatch #11
Six weeks of CPython news: Python 3.15.0 final, new PEPs for None-aware access and coalescing operators, PEP 755 withdrawn in favor of PyPI policy, the inaugural Python Packaging Council election results, and two new core developers.

Django Job Board
Django roles were light this week, so here are two machine learning openings at HFT Architecture, one senior and one junior, that should appeal to Python and Django developers looking to branch out.

Projects
pradeeppc/django-permission-tracer
DRF permissions end up spread across permission_classes, @action overrides, get_permissions() and composed expressions. This resolves all of it into an endpoint-to-permission map, traces which operand denied a given request, and flags endpoints an anonymous user can reach, with --fail-on-unprotected for CI.
pradeeppc/django-q-watchdog
When a django-q worker dies mid-task, the task simply vanishes: no failed row, no traceback. This records each task as it starts and heartbeats while it runs, so lost and timed-out tasks land in django-q's own Failed tasks, and a hung one gets reported as frozen.

Pycon NL: what's inside an asyncio event loop? - Taras Kozlov
(One of my summaries of the 2026 one-day Pycon NL conference in Utrecht, NL).
An asyncio event loop is defined by asyncio.AbstractEventLoop. That's a large API with more than 50 public methods, but only three are fundamental. At the lowest useful leve, the loop manages callbacks, i/o and timers.
- We need a way to put events on a queue and a way to grab events from a queue and execute them. call_soon()
- We need timers too, for callbacks that must be run after some time. call_later()
- Sleep only knows about time. Often we want to sleep until the next time, unless a socket becomes ready first. So we need a "sleep" that can be interrupted by I/O readiness. add_reader(), add_writer()
His own example implementation of asyncio for educational purposes is at: https://github.com/tarasko/eduloop , it is only 250 lines. Handy if you want to understand asyncio.
He showed this simple example code, incrementally implementing the points above.
The nice thing about asyncio is coroutines. A coroutine is an extended kind of function that can be paused and resumed. The result is a "future". A future represents an eventual result of an async operation. So: a future is pending until somebody supplies either a result or an exception.
For network connection there's Transport and Protocol.

Pycon NL: building resumable Python pipelines - Yuvraj Singh Pathania
(One of my summaries of the 2026 one-day Pycon NL conference in Utrecht, NL).
Full title: fire, forget, regret: building resumable Python pipelines.
If you run a task in an async loop, there's often no reference to the task. So it can be garbage collected! You can solve that by keeping a reference in some list. But even then, the whole process can die. What happens with your task then?
Often you have to re-run the task. He himself is into LLMs, so failed tasks that you have to re-run can become expensive.
BackgroundTasks is part of FastAPI and it works great for spinning off longer running tasks. Real handy, but there is no retry mechanism and no recoverability in case of crashes. "Fire-and-forget".
You can use specific task queues. ARQ, Celery, Dramatiq. In this case, the job itself is safe and can be re-tried. But not the individual steps within the job.
What he wants is durable execution. Write down every step you finish; on restart, skip what is written. It can save you lots of time (and possibly money). It might be simpler to set up than you think.
His code + slides are at https://github.com/batman004/fire-forget-regret
