The views.settings:ui.exposed_filter_any_label configuration key has been removed, along with its select field on the Views settings form (/admin/structure/views/settings).
The setting only ever controlled the label shown for the "Any" row in a view's grouped exposed filter configuration table in the admin UI. It had no effect on what site visitors see: the exposed filter widget itself has always rendered "- Any -" regardless of this setting.
Before
Sites could choose between "<Any>" (old_any) and "- Any -" (new_any) for the top row label in the grouped exposed filters configuration table. The chosen value was stored in views.settings:ui.exposed_filter_any_label.
After
The setting and its form field are removed. The grouped exposed filters configuration table always shows "- Any -", matching what visitors already saw on the exposed filter form. A post-update function removes the key from existing sites' configuration.
What you need to do
If your code reads views.settings:ui.exposed_filter_any_label (via config or the config schema), remove that usage - the key no longer exists after running database updates. No action is needed if you only relied on the default exposed filter behavior, since that was never affected by this setting.
