DJANGO DEPRECATES SELECT_RELATED() WITH NO ARGUMENTS

Django is removing the footgun of calling `select_related()` without arguments, forcing developers to be explicit about which relations they want to optimize.

The main event is a deprecation wave [1] that closes off a common mistake: calling `QuerySet.select_related()` with no args used to load every relation, defeating the purpose of the method entirely. This lands alongside a companion deprecation [2] that removes the corresponding `ModelAdmin.list_select_related = True` shortcut, which had the same problem. The infrastructure work behind this is solid—the team also removed unnecessary ordering from compound queries [3] and cleaned up test dependencies on generated columns [4], both of which reduce unnecessary database operations. On the admin side, hardcoded primary keys are gone from permission tests [5], making the test suite more maintainable as it scales. Benchmark infrastructure is tracking performance across ubuntu-latest [6], so you'll see the real-world impact of these changes roll in.

Action items

→ Audit your codebase for bare select_related() calls before the next Django LTS django/django [plan]
→ Check ModelAdmin subclasses for list_select_related = True and replace with explicit tuples django/django [plan]
