## [Unreleased]

## [0.3.1] - 2026-11-02

### Fixed

- `yaml_to_json` now treats `!!binary`-tagged scalars as literal strings instead
  of silently base64-decoding them, preventing value corruption for annotated
  YAML documents.

### Added

- Regression tests for ragged-row rejection in CSV/TSV and `!!binary`
  string preservation.
- Documented that non-string YAML keys are stringified, matching mainstream
  YAML-to-JSON converters.

## [0.3.0] - 2026-11-02

### Added

- YAML output for all tabular sources: `csv_to_yaml`, `tsv_to_yaml`, `json_to_yaml`.
- YAML input for all tabular targets: `yaml_to_csv`, `yaml_to_tsv`, `yaml_to_json`.
- Direct `csv_to_tsv` and `tsv_to_csv` conversions.
- CLI subcommands for every new route.
- YAML support uses `serde-saphyr` (pure Rust, YAML 1.2, no C dependency).

### Fixed

- `csv_to_json` / `tsv_to_json` now strip UTF-8 BOM before parsing, so
  Excel-exported files no longer produce headers like `\u{feff}name`.
- `yaml_to_json` uses `strict_booleans` to avoid the YAML 1.1 "Norway problem":
  `yes`/`no`/`on`/`off` are kept as strings, matching YAML 1.2 semantics.
- `json_to_yaml` and `yaml_to_json` preserve `null` values instead of
  stringifying them.
- `json_to_csv` / `json_to_tsv` build the header from the union of all object
  keys in first-appearance order, guaranteeing stable round-trips regardless
  of per-object key ordering.
- `json_to_tsv` correctly quotes cells containing tab characters, preventing
  line-splitting corruption.
- Dependencies pinned to `serde-saphyr` `0.0.29` (pure Rust, YAML 1.2, no C
  dependency) to keep the crate portable to Android/Termux.

## [0.2.0] - 2026-11-02

### Added

- `tsv_to_json` and `json_to_tsv` library functions.
- `tsv-to-json` and `json-to-tsv` CLI subcommands.
- TSV support reuses the same lossless conversion engine as CSV, with
  identical duplicate-header and nested-value rejection rules.

## [0.1.2] - 2026-11-02

### Fixed

- `csv_to_json` now errors on duplicate CSV headers instead of silently
  dropping columns.
- `json_to_csv` now collects the union of keys across all objects instead
  of using only the first object's keys, which silently dropped data.
- `json_to_csv` now errors on nested JSON objects/arrays instead of
  stringifying them and corrupting round-trips.

## [0.1.1] - 2026-11-02

### Changed

- Rename crate from `sheeter` to `sheeter-engine` to avoid collision with an
  existing crate on crates.io. Import path changes from `sheeter::` to
  `sheeter_engine::`.

## [0.1.0] - 2026-11-02

### Added

- Initial release of Sheeter CLI.
- CSV to JSON conversion.
- JSON to CSV conversion.
- Support for reading from and writing to files.
