What’s New in libchewing 0.9.0 (August 11, 2024)

Features
- Support two new input modes:
  - Fuzzy mode - support prefix search, partial zhuyin search, toneless input.
  - Simple mode - like the traditional input method on Windows 95 which does not perform any intelligent phrasing.
- Allow space key for pagination regardless of space_is_select_key mode.
- Merge DOWN and SPACE key behavior in pagination.
- A new option to disable fullwidth toggle key.
- Workman layout support.
- Load embedded mini dictionary if system dictionaries were not found.
- Automatically load extra dictionaries found in search path
  - ${CHEWING_PATH}/dictionary.d/*.dat
- Automatic snapshot selections when the curser is moved.
Developer Features
- BREAKING: Remove language_mode and character_form methods (Rust).
- BREAKING: Remove unused pinyin.tab file
- BREAKING: Remove most unused C code but keep compat C headers.
- Bump minimum supported Rust version to 1.77
- Enable ELF symbol versioning. All existing symbols are marked as version CHEWING_0.5 and new symbols from this release are marked as CHEWING_0.9.
- A new set of configuration API:
  - chewing_config_has_option
  - chewing_config_get_int
  - chewing_config_set_int
  - chewing_config_get_str
  - chewing_config_set_str
- New API to get runtime library version:
  - chewing_version
  - chewing_version_major
  - chewing_version_minor

  - chewing_version_extra
- New API to acknowledge output buffers:
  - chewing_ack

Bug Fixes
- Separate special handling by pinyin variants (#298)
- Panic when selecting phrases backwards at the end of buffer. (introduced in v0.8.0)
Dictionary

- Generate test cases from fuzzer input.
Miscellaneous Tasks
- Drop outdated ChangeLog
- Add option to turn off tests run
- Use system corrosion if available
- Regenerate chewing.h using latest cbindgen
- Include CTest and use the built-in BUILD_TESTING option
- Manage SQLite dependency with CMake
- Print status about SQLite3 module
- Remove unused test files
- Bump Corrosion to v0.5
