## [Unreleased]

## [0.3.0] - 2025-12-11

### Added
- CHANGELOG file
- Expose version via `Money.version/0`
- Add and run doctests for `sigil_M/2` and `allocate/2`
- Add support for underscores when using sigil shorthand
- `Money.Util.normalize_ratios/1` as a test helper for testing `Money.allocate/2`
  with fractional allocation parts (instead of integer) to recreate a specific
  complex test case. It's not yet part of the public API - still deciding.

- Fix handling of negative amounts for `Money.allocate/2`

### Changed
- README minor edits

### Added

- Add specs and types for string functions

### Changed
