Changelog

Sourced from django-upgrade's changelog.

1.32.0 (2026-08-18)

• Support Python 3.15.

  PR [#681](https://github.com/adamchainz/django-upgrade/issues/681) <https://github.com/adamchainz/django-upgrade/pull/681>__.

• Fix :ref:utils_text <utils_text> fixer to rewrite unescape_entities() calls with html.unescape(). Previously it incorrectly used html.escape(), which performs the inverse operation.

  PR [#684](https://github.com/adamchainz/django-upgrade/issues/684) <https://github.com/adamchainz/django-upgrade/pull/684>__.

• Fix :ref:index_together <index_together> fixer crash on empty index_together declarations.

  PR [#685](https://github.com/adamchainz/django-upgrade/issues/685) <https://github.com/adamchainz/django-upgrade/pull/685>__.

• Fix :ref:index_together <index_together> fixer to not add a duplicate indexes declaration when the existing one is not a list or tuple literal.

  PR [#686](https://github.com/adamchainz/django-upgrade/issues/686) <https://github.com/adamchainz/django-upgrade/pull/686>__.

• Fix :ref:index_together <index_together> fixer to add a missing comma when extending a multiline indexes list that has no trailing comma.

  PR [#687](https://github.com/adamchainz/django-upgrade/issues/687) <https://github.com/adamchainz/django-upgrade/pull/687>__.

• Fix :ref:index_together <index_together> fixer to keep an empty indexes tuple a tuple when extending it with a single index.

  PR [#716](https://github.com/adamchainz/django-upgrade/issues/716) <https://github.com/adamchainz/django-upgrade/pull/716>__.

• Fix :ref:format_html <format_html> fixer to skip calls with a parenthesized argument, where removing the .format() call would create a tuple.

  PR [#717](https://github.com/adamchainz/django-upgrade/issues/717) <https://github.com/adamchainz/django-upgrade/pull/717>__.

• Fix :ref:null_boolean_field <null_boolean_field> fixer to add a missing comma before null=True when the final argument contains commas within brackets.

  PR [#688](https://github.com/adamchainz/django-upgrade/issues/688) <https://github.com/adamchainz/django-upgrade/pull/688>__.

• Fix fixers that modify call arguments to not treat a comment inside otherwise empty parentheses as an argument, which made the :ref:null_boolean_field <null_boolean_field> fixer produce invalid syntax.

  PR [#718](https://github.com/adamchainz/django-upgrade/issues/718) <https://github.com/adamchainz/django-upgrade/pull/718>__.

• Fix :ref:test_http_headers <test_http_headers> fixer to avoid a double comma when the existing headers= dict has a trailing comma.

  PR [#689](https://github.com/adamchainz/django-upgrade/issues/689) <https://github.com/adamchainz/django-upgrade/pull/689>__.

• Fix :ref:test_http_headers <test_http_headers> fixer to insert converted headers at the start of an existing headers= dict. Django gives headers= entries precedence over HTTP_ arguments, and the last duplicate key wins in a dict literal, so appending converted entries at the end previously flipped which value took effect.

  PR [#723](https://github.com/adamchainz/django-upgrade/issues/723) <https://github.com/adamchainz/django-upgrade/pull/723>__.

• Fix :ref:testcase_databases <testcase_databases> fixer to rewrite multi_db = False to databases = ["default"] rather than databases = [].
