Known Issues

List of deprecated SudachiPy API:
- MorphemeList.empty(dict: Dictionary)
  - This also needs a dictionary as an argument.
- Morpheme.split(mode: SplitMode)
- Morpheme.get_word_info()
- Most of instance attributes are not exported: e.g. Dictionary.grammar, Dictionary.lexicon.
  - See API reference page for supported APIs.
Dictionary Build is not supported: sudachipy build and sudachipy ubuild will not work, please use 0.5.3 in another virtual environment for the time being until the feature is implemented: #13
