v2.0.0

Added

• 16 new languages compiled from Snowball 3.0.1 sources:
  Armenian, Basque, Catalan, Czech, Esperanto, Estonian, Hindi, Indonesian, Irish, Lithuanian, Nepali, Norwegian, Persian, Polish, Serbian, Yiddish
• Finnish added to supported languages in README (was already implemented)
• Functional API — three levels of usage:
  • Named language functions: russian('бегущий') → 'бег'
  • Factory: createStemmer('ru') returns a reusable (word: string) => string
  • Raw: stem('ru', 'бегущий')
• ISO 639-1 code support — pass 'ru', 'en', etc. alongside Languages enum values
• Browser support — conditional exports (node / browser / default); single --target web WASM build shared by both environments; WASM initializes automatically on import, no init() call needed
• Interactive demo at demo/index.html — word-by-word stemming diff with 33 language samples
• GitHub Actions workflow deploying the demo to GitHub Pages

Changed

• Minimum Node.js version is now 22
• Package is now pure ESM ("type": "module") — use import instead of require
• Entire codebase migrated from JavaScript to TypeScript 6 (module: NodeNext)
• SOLID architecture: single-responsibility modules, dependency injection via iso-map.ts
• wasm-bindgen updated from 0.2.45 to 0.2.121
• Rust codebase migrated to edition 2024 — removed extern crate, updated module paths to crate:: prefix
• Snowball runtime (SnowballEnv, Among) replaced with official Snowball 3.0 version: i32 positions, new go_in_grouping / go_out_grouping methods, all algorithms recompiled from source
• opt-level = "s" added to release profile (optimize for size)
• Test suite migrated to Vitest, one test per language (43 tests total)
• packageManager field set to pnpm@11

Removed

• Class-based new Stemmer(Languages.X) API (replaced by functional API above)
• CommonJS support — package is ESM-only
• serde / serde_derive dependencies
