[0.3.0] - 2026-07-23

Collation resolution carries all collation-affecting BCP 47 -u- keywords (kn, ks, kc, kf, ka, kb, kr, kv) into the collation name, so collate(f.name, "en-u-kn-true") finds a natural-sort collation created in a migration.
create_collation/2 accepts tailoring options (:strength, :numeric, :case_level, :case_first, :alternate, :backwards) using the Localize.Collation.Options vocabulary. Primary and secondary strengths default to a nondeterministic collation, enabling case/accent-insensitive equality and unique indexes.
mix localize.ecto.audit and Localize.Ecto.Audit report collation version drift with per-index remediation SQL, database default collation drift, server-versus-application Unicode/ICU/CLDR versions, and time zone inventory differences.
Localize.Ecto.Type.TimeZone is an Ecto type for IANA time zone identifiers, canonicalizing aliases and BCP 47 short zone ids against the CLDR inventory; at_time_zone/2 applies a validated AT TIME ZONE.
Localize.Ecto.TextSearch.config_for/2 resolves a locale to the best PostgreSQL text search configuration, and ts_match/2,3 builds a locale-aware to_tsvector … @@ websearch_to_tsquery match.
lower/1,2, upper/1,2 and initcap/1,2 apply locale-aware case mapping via the locale's collation ("INDIGO" lowercases to "ındıgo" under "tr").

Initial release.

Localize.Ecto.collate/1,2 query macros applying PostgreSQL ICU COLLATE clauses to query expressions and comparisons, resolved from a locale or the current Localize locale.
Locale-to-collation resolution via CLDR language matching, including BCP 47 -u-co- collation types and direct collation names.
Localize.Ecto.Migration.create_collation/2 and drop_collation/2 for creating ICU collations reversibly in migrations, and collated/2 for building collated indexes with Ecto.Migration.index/3.
