v0.11.0

What's New in libchewing 0.11.0 (January 10, 2026)

• Features

  • cli: Now outputs and reads dictionary metadata in source file
  • cli: Detects mismatched phrase word count and syllable count
  • cli: Ignores empty line or line starts with # when processing dictionary
  • editor: Support optional sorting candidates by frequency. Previously the
    candidates are always sorted by their order in the dictionary.

• Developer Features

  • New API chewing_handle_KeyboardEvent() can be used to support any
    keyboard layout combination without updating libchewing. Other keyboard
    handling API will be deprecated in future release.
  • New API chewing_new3() and chewing_get_defaultDictonaryNames() can be
    used to initialize a chewing context with specific dictionaries enabled.
  • New boolean config option chewing.sort_candidates_by_frequency can be
    set to enable sorting candidates by frequency.
  • Rust type SyllableSlice is removed from public interfaces.
  • Provide libchewing as a Swift package (C based API only).

• Bug Fixes

  • Auto shift cursor after candidate selection now moves the cursor to the
    next phrase instead of the next word.
  • Fixed a bug when switching input mode from Chinese to English, the state
    can be stuck in entering bopomofo.
  • Fixed the frequency estimation function used by phrase learning to really
    take last used time into consideration. Also assign higher frequency to
    newly learned phrases.

• Changes

  • SQLite support is now fully optional and disabled by default
  • rust: new sqlite-bundled feature can be used to build with bundled sqlite
    to simplify the build configuration on Windows
  • cli: will try to migrate to new schema when dumping chewing.sqlite3 file
  • Use less heuristic when calculating phrase segmentation score.
  • Reimplement scoring algorithm to use conditional probability.
  • cli: init-database will no longer normalize the frequency of single word
    phrase to zero.
  • autolearn: new phrases with break words inside will be learned both with
    and without the break word.
  • rust: simplified dictionary API.
  • rust: the DictionaryMut trait is merged back to the Dictionary trait.
  • rust: the Editor::set_editor_options now accepts a closure for setting
    options in place.
