Bump django-htmx from 1.28.0 to 1.29.0

[dependabot]

Bumps django-htmx from 1.28.0 to 1.29.0.

Changelog

Sourced from django-htmx's changelog.

1.29.0 (2026-08-06)

• Vendor some stable htmx extensions, named per their htmx 4 versions: htmx-2-compat, hx-browser-indicator, hx-download, hx-head, hx-optimistic, hx-preload, hx-prompt, hx-ptag, hx-sse, hx-targets, hx-upsert, and hx-ws. Render their script tags with the new extensions argument of the htmx_script :doc:template tags \<template_tags>, which selects the extension files matching the htmx version in use:

  .. code-block:: django

  {% htmx_script version=4 extensions="hx-sse,hx-ws" %}
  

  hx-head, hx-preload, hx-sse, and hx-ws are available for both htmx versions 2 and 4; the rest are htmx 4 only.

  The special name htmax renders htmx 4’s htmax bundle of htmx plus its most popular extensions, in place of the plain htmx script:

  .. code-block:: django

  {% htmx_script version=4 extensions="htmax" %}
  

  PR [#614](https://github.com/adamchainz/django-htmx/issues/614) <https://github.com/adamchainz/django-htmx/pull/614>. Thanks to Rex Zhang for initial work in PR [#575](https://github.com/adamchainz/django-htmx/issues/575) <https://github.com/adamchainz/django-htmx/pull/575/commits>.

• Upgrade the vendored htmx 2 to version 2.0.10 <https://github.com/bigskysoftware/htmx/blob/master/CHANGELOG.md#2010---2026-04-21>__.

  PR [#594](https://github.com/adamchainz/django-htmx/issues/594) <https://github.com/adamchainz/django-htmx/pull/594>__.

• Upgrade the vendored htmx 4 to version 4.0.0-beta6 <https://github.com/bigskysoftware/htmx/releases/tag/v4.0.0-beta6>__.

  PR [#610](https://github.com/adamchainz/django-htmx/issues/610) <https://github.com/adamchainz/django-htmx/pull/610>__.

• Add support for the polling tags protocol of the htmx 4 |hx-ptag extension|__:

  • :attr:HtmxDetails.ptag <django_htmx.middleware.HtmxDetails.ptag> reads the HX-PTag request header directly.

  • The :func:django_htmx.http.ptag view decorator implements the protocol, with an API mirroring Django’s |etag decorator|__. It computes the current tag with the given function and, when the HX-PTag request header matches, returns a 304 (Not Modified) response without calling the view, making htmx skip the swap. Otherwise, it calls the view and sets the HX-PTag response header.

  .. |hx-ptag extension| replace:: hx-ptag extension __ https://four.htmx.org/extensions/hx-ptag

  .. |etag decorator| replace:: etag decorator __ https://docs.djangoproject.com/en/stable/topics/conditional-view-processing/

  PR [#613](https://github.com/adamchainz/django-htmx/issues/613) <https://github.com/adamchainz/django-htmx/pull/613>__.

• Switch package build backend from setuptools to uv_build <https://docs.astral.sh/uv/concepts/build-backend/>__. This makes builds with uv about nine times faster, since uv runs the backend natively, without creating a build environment or spawning a Python process. Additionally, source distributions no longer include test files, which setuptools previously included incompletely, missing the files needed to actually run them.
