mmucklo/inflect

First major release of mmucklo/inflect in over a decade. Modernizes the PHP baseline, ports tests to PHPUnit 10, moves to PSR-4, adds GitHub Actions CI with Codecov and Scrutinizer, tightens types, and expands correctness.

⚠️ Breaking changes

• PHP 8.1+ required. Previous floor was PHP 5.3.17. Callers on ≤ PHP 8.0 cannot upgrade — stay on the php5.3 branch for back-ported fixes to the legacy baseline.
• PSR-4 file layout. src/Inflect/Inflect.php moved to src/Inflect.php. Composer autoload changed from psr-0 to psr-4. autoload.php.dist was removed.
• Inflect is now final. Subclassing is no longer supported. Locale support (v2.2) will extend via composition.
• Static rule tables (\$plural, \$singular, \$irregular, \$uncountable) and caches are now private. External code that was reading or mutating these will break. Supported extension APIs are roadmap §5 (v2.1).
• pluralize(null) / singularize(null) now throw TypeError. Previously returned null silently. Empty strings still return '' without error.
• pluralizeIf uses strict comparison (===) for the count check. Callers passing '1' as a string now hit the plural branch.
• phpunit.xml-dist renamed to phpunit.xml.dist (PHPUnit 10 convention). CI automation reading the old name must update.

✨ Added

• GitHub Actions CI on PHP 8.1 / 8.2 / 8.3 / 8.4 (#13).
• Codecov coverage reporting (98.07% on master) (#13, #16).
• Scrutinizer quality analysis (#13, #17).
• 9 new irregular inflections: datum/data, criterion/criteria, phenomenon/phenomena, cactus/cacti, nucleus/nuclei, syllabus/syllabi, curriculum/curricula, medium/media, bacterium/bacteria (#9).
• 10 new uncountables: news, aircraft, software, hardware, luggage, advice, traffic, furniture, metadata, multimedia (#9).
• Case preservation on irregular transforms: Man → Men, Children → Child (previously lowercased) (#9).
• Double-inflection guard: pluralize('people') now returns 'people' (was 'peoples'); singularize('datum') stays 'datum' (was 'data') (#9).
• Case-insensitive uncountable lookup in pluralize() to match singularize() behavior (#9).
• declare(strict_types=1), string/int parameter and return types on all public methods (#14).
• Typed static properties (PHP 7.4+ syntax) (#14).
• Expanded test suite: 117 tests / 118 assertions, ported to namespaced PHPUnit\Framework\TestCase with #[DataProvider] attributes (#12, #14).
• ROADMAP.md documenting planned improvements and the locale-support path (A: vendored; B: sibling mmucklo/inflections package) (#8, #11, #15).

🔧 Changed

• PHPUnit bumped from 3.7.* to ^10.5 (#12).
• Autoload switched from PSR-0 to PSR-4; tests live in the Inflect\Tests namespace (#12).
• Short array syntax ([]) throughout the class (#14).
• Issue #4 fix (singularization of -ss words like business, wellness) is included.

🗑 Removed

• autoload.php.dist — obsoleted by Composer PSR-4 autoload.
• .travis.yml — replaced by GitHub Actions.

🌿 Branching

• master — active development, PHP 8.1+.
• php5.3 — back-port branch for critical fixes on the legacy baseline. All v2.0 correctness fixes were back-ported (#10).
