In [changeset:"0c634de4e6950ec6fb83ab420b4af9c645b28acd" 0c634de]:
{{{#!CommitTicketReference repository=""
revision="0c634de4e6950ec6fb83ab420b4af9c645b28acd"
Refs #36593 -- Made ModelAdmin.list_select_related = False more efficient.
This change makes `list_select_related = False` avoid unnecessary joins by
only
selecting the related fields that are actually used in `list_display`.
Consequently, it avoids one code path that calls
`QuerySet.select_related()`
with no arguments, which is targeted for deprecation.
