Refs #36593 -- Deprecated setting ModelAdmin.list_select_related to True.

2026-05-11T16:32:30Z

Now that calling `QuerySet.select_related()` without arguments is deprecated, this commit deprecates the corresponding admin features.

Reverted inadvertent changes to PK formatting in tests.

Bad conflict resolution in 63c56cda133a85a158502891c40465bc0331d3d9 reverted bits of d007fcf7291cc3c24d4545e23c759bde22b6a8a6.

Fixed #10919 -- Added delete_confirmation_max_display to ModelAdmin.

2026-04-23T02:22:55Z

The new ModelAdmin.delete_confirmation_max_display attribute allows limiting the number of related objects shown on the delete confirmation page. When the limit is reached, a "…and N more objects." message is shown. The feature relies on a new truncated_unordered_list template filter added to django.contrib.admin.templatetags.admin_filters. Thanks Jacob Tyler Walls for the review and guidance, Tobias McNulty for the report, and terminator14 for the solution suggested.

2026-04-22T21:06:29Z

Refs #36949 -- Removed hardcoded pks in modeladmin tests.

Fixed #36949 -- Improved RelatedFieldWidgetWrapper s.

2026-04-02T15:09:37Z

Regression in 4187da258fe212d494cb578a0bc2b52c4979ab95.

Modified tests to format PKs with %s rather than %d.

2026-02-10T21:04:24Z

It's how Django formats values internally and makes tests compatible with databases that use non-integer primary keys.

Fixed #36804 -- Fixed admin system check crash for missing models.
