v2.1.0 — Snowball 3.1.1, Sesotho, 34 languages

Added

• Sesotho (st) stemmer — new in Snowball 3.1.0, brings the total to 34 languages
• Test corpus voc_st.txt / res_st.txt from snowball-data

Changed

• All stemmers regenerated from Snowball 3.1.1 (were Snowball 3.0.0)
• Stemming results change for words containing apostrophes and elisions in Danish,
  Estonian, Finnish, German, Italian, Lithuanian, Norwegian and Polish
• English — skis stems to ski again (regression introduced upstream in Snowball 3.0.0)
• Danish — undoubling restricted to consonant pairs that actually occur in Danish
• Finnish — illative fallback now removes -n when the vowel before -han/-hen/-hin/-hon/-hän/-hön
  does not match; illative form -hun removed
• Lithuanian — -er- is no longer removed before regular suffixes
• Test corpora for Danish, Estonian, Finnish, French, German and Norwegian synced with snowball-data
• Dev dependencies updated: pnpm 11.19.0, @types/node 22.20.1, tsx 4.23.2, vitest 4.1.10, wasm-pack 0.15.0

Fixed

• Node.js entry no longer logs using deprecated parameters for the initialization function —
  the WASM binary is passed to init() as { module_or_path }

Note

• Sesotho is inserted alphabetically into the Languages enum, so the numeric values of
  Spanish through Yiddish shift by one. Code using Languages.X or ISO codes is unaffected;
  hardcoded numeric values are not.
