3.0.0

Breaking Changes

• ROL → RON: Romanian currency code updated from deprecated ROL to current ISO 4217 code RON across all transformers
• PHPUnit 9 → 11: Test infrastructure upgraded (requires PHP 8.2+)

New Features

• Base currency list: All currency transformers now support a canonical set of 51 currencies. Previously several transformers had only 2–14 currencies; all now have full coverage
• MXN (Mexican Peso): Added to all currency transformers that were missing it
• Malay currency transformer: MalaysianCurrencyTransformer renamed to MalayCurrencyTransformer for naming consistency with MalayNumberTransformer

Bug Fixes

• Swedish: Fixed capitalized Minus prefix, sjutio → sjuttio (70), missing plural inflection for millions/billions
• Danish: Missing og connector after hundreds (e.g. et hundrede en → et hundrede og en)
• German currency: eins Euro → ein Euro for amounts of 1, and ein tausend → eintausend (wrong word separator)
• Yoruba: Zero returned empty string instead of odo
• Romanian currency: Negative amounts ignored the minus sign

Test Coverage

• Added ~120 new test cases across 16 transformers covering: negative numbers, full numeric ranges, and newly added currencies
• Added MXN test cases in 8 languages (English, German, Polish, Russian, Spanish, French, Danish, Turkish)

CI / Infrastructure

• Migrated from Code Climate to Qlty.sh for coverage reporting (QLTY_COVERAGE_TOKEN)
• xdebug now installed via pecl instead of deprecated install-php-extensions (fixes PHP 8.5 support)
• HTML coverage report saved as CircleCI artifact
• PHPUnit annotations (@dataProvider) replaced with PHP 8 attributes (#[DataProvider])
• Data provider methods made public static (PHPUnit 11 requirement)
• Abstract base test classes renamed: CurrencyTransformerTest → CurrencyTransformerTestCase, NumberTransformerTest → NumberTransformerTestCase

Removed

• src/Legacy/Numbers/Words/Locale/Uz.php: dead code - Uzbek has its own modern transformer
