and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [0.1.0] - 2025-12-27

### Added
- String-keyed schema fields and nested object schema DSL (`Schema.object/1`).
- Built-in format types (`:date`, `:datetime`, `:uuid`, `:null`, `{:nullable, type}`).
- JSON encode/decode helpers with transform pipeline (`Sinter.JSON`, `Sinter.Transform`, `Sinter.NotGiven`).
- Example runner `examples/run_all.sh` and refreshed example suite.

### Changed
- Big-bang refactor of core schema/validation architecture per technical design.
- JSON Schema validation now uses `jsv` 0.13.1 with Draft 2020-12 default and Draft 7 provider support.
- Provider JSON Schema generation applies strictness recursively for nested objects.
- Schema inference avoids atom leaks by defaulting to string keys.

### Fixed
- Required/default ordering so defaults apply before required checks.
- `validate_many/3` base path ordering.

## [0.0.2] - 2025-12-27

### Changed
- Switched JSON Schema validation to `ex_json_schema` v0.11.2.
- Updated generated `$schema` to JSON Schema Draft 7 for validator compatibility.
- Removed custom JSON Schema structural validation helpers in favor of meta-schema validation.
