“View Collection” button: on collection cards (the collections index, the related-collections sidebar, and collection-grid website sections) the button ignored the configured translated or custom label and always showed English. It now uses the configured label everywhere collection cards appear.
Min/max passenger warning: the booking-form warning shown when a departure is below its minimum or near its maximum was overridden by an easily-missed per-trip field that the editor auto-filled, so customised or translated wording was silently ignored. It now always uses the configured text, on the booking form and in the related confirmation emails.
Why the change: most sites were overriding their own localization without realising this per-trip field existed. Rather than keep a setting that quietly shadows Localization, it has been removed; warning text is still customisable per language under Website > Localization.
