- lagoon.OrderBy takes variadic lagoon.OrderOption values; lagoon.Collate(name) emits a validated, double-quoted COLLATE clause (e.g. "pl-x-icu") - remove the exported CheckLocale and the ICU pl-PL check from Open and Use - framework test containers and per-test databases are plain PostgreSQL - lagoon README, root README and docs pages drop the locale requirement; queries-and-pagination gains a "Sorting with a collation" section backed by ExampleCollate
