## [Unreleased]

## [0.2.1] - 2024-06-12

### Fixed

- Fix the exception when a string contains unicode characters.


## [0.2.0] - 2024-05-08

### Added

- Add support for `int8`, `uint8`, `uint16`, `uint32`, `uint64`, `large_string`, and `large_binary` type.
- Support listing functions.

### Breaking Changes

- `json` and `decimal` type are no longer mapped to `LargeString` and `LargeBinary` respectively. They are now mapped to [extension types](https://arrow.apache.org/docs/format/Columnar.html#format-metadata-extension-types) with `String` as the storage type.
    - `json`: `ARROW:extension:name` = `arrorudf.json`
    - `decimal`: `ARROW:extension:name` = `arrowudf.decimal`
