+# Changelog

+## 0.1.1 (2026-04-06)
+
+### Bug Fixes
+
+- **normalize:** Handle `nullable: true` without `type` in OpenAPI 3.0 schemas. Schemas using `nullable` on `allOf` compositions or bare description objects were not being normalized, causing Ajv to throw `"nullable" cannot be used without "type"`.
+
+## 0.1.0 (2026-04-06)
+
+### Features
+
+- Initial release
+- Validate JSON payloads against OpenAPI 3.0/3.1 specs
+- Full `$ref` resolution with nested component references
+- OpenAPI 3.0 to 3.1 schema normalization (`nullable`, `exclusiveMinimum`, `exclusiveMaximum`)
+- Human-friendly validation error messages
+- Reusable Ajv instance for performance
+- CI/publish workflows
