35316	Support scalars as query parameters in admin changelist filters (for backward compatibility).	Manolis Stamatogiannakis	nobody	"Ticket #1873 added support for multi-valued query parameters in admin changelist filters. Because only list types are supported, older code that e.g. extends SimpleListFilter or BooleanFieldListFilter will break.

The latter (extending BooleanFieldListFilter) may even be completely unsupported. See notes in PR for #1873.

Overall, user code needs to introduce version conditionals if it is required to support both Django 4.x and Django 5. The reason is that Django 4.x only supports scalar types as query parameter values, while Django 5 only supports lists.

Since supporting both scalars and lists should be possible without adding complexity to the Django codebase, it would be good to continue supporting scalars, perhaps with a deprecation warning, if necessary."	Uncategorized	closed	contrib.admin	5.0	Normal	wontfix		Sarah Boyce	Unreviewed	1	0	0	0	1	0
