0.4.0 - 2026-04-05

Fixed

• Bcp47LanguageTag.parse now uses typed catch (e) { if (e is! ArgumentError) rethrow; } instead of catch (_) {}, preventing silent swallowing of genuine runtime errors.
• kIrregularTags and kRegularTags replaced with explicit const <String>[...] list literals.

Changed

• Bcp47Subtags changed from Iterable<String> to List<String>.
• Bcp47GrandfatheredTag.irregular changed from late final to final (computed inline).
• Bcp47Lookup and Bcp47Validator members promoted to top-level functions; deprecated class wrappers retained for backward compatibility.

0.3.0 - 2026-03-28

Fixed

• Fix == and hashCode in Bcp47LanguageTagMixin to use structural, case-insensitive comparison (was identity-based, causing map/set lookups to fail).
• Fix Bcp47BasicLanguageRange.parse to accept single-subtag ranges (e.g. 'en', 'de').

Changed

• Update IANA registry data (registry date 2025-08-25, latest record 2024-12-12).

Added

• Add Bcp47Lookup with basicFilter, extendedFilter, and lookup (RFC 4647 §3.3 and §3.4).
• Add Bcp47LangTag.copyWith for type-safe field replacement.
• Add /// doc comments to all public API members.
