Brian #1: Advent of Code starts today

A few changes, like 12 days this year, which honestly, I’m grateful for.

Michael #2: Django 6 is coming

Expected December 2025

Django 6.0 supports Python 3.12, 3.13, and 3.14

Built-in support for the Content Security Policy (CSP) standard is now available, making it easier to protect web applications against content injection attacks such as cross-site scripting (XSS).

The Django Template Language now supports template partials, making it easier to encapsulate and reuse small named fragments within a template file.

Django now includes a built-in Tasks framework for running code outside the HTTP request–response cycle. This enables offloading work, such as sending emails or processing data, to background workers.

Email handling in Django now uses Python’s modern email API, introduced in Python 3.6. This API, centered around the email.message.EmailMessage class

Brian #3: Advanced, Overlooked Python Typing

get_args, TypeGuard, TypeIs, and more goodies

Michael #4: codespell

Learned from this PR for the Talk Python book.

Fix common misspellings in text files.

It's designed primarily for checking misspelled words in source code (backslash escapes are skipped), but it can be used with other files as well.

It does not check for word membership in a complete dictionary, but instead looks for a set of common misspellings. Therefore it should catch errors like "adn", but it will not catch "adnasdfasdf".

It shouldn't generate false-positives when you use a niche term it doesn't know about.

Extras

Brian:

Is mkdocs maintained?

Hatch 1.16

Michael:

Follow up on tach from Gerben Dekker:

tach has been unmaintained for a bit but is not anymore. It was the main product from Gauge which is a Y combinator startup that pivoted to something unrelated and abandoned tach. However, https://github.com/DetachHead forked it but now got access to the main repo and has committed to maintaining it.

ruff analyze graph is fully independent of tach - we actually started to look into alternatives for tach when it became unmaintained and then found ruff analyze graph.

For our use case, with just a bit of manipulation on top of ruff analyze graph we replaced our use of deptry (which was slower - and I try to be careful depending on one-man projects).

A Review of Michael Kennedy’s book, “Talk Python in Production” - Thanks Doug
