+## [3.0.1](https://github.com/ByteBardOrg/AsyncAPI.NET/compare/v3.0.0...v3.0.1) (2026-08-02)
+### Bug Fixes
+* corrected rule ([#36](https://github.com/ByteBardOrg/AsyncAPI.NET/issues/36)) ([0496eb5](https://github.com/ByteBardOrg/AsyncAPI.NET/commit/0496eb5549abf3095e960ed870fa25eb71f463c6))
+
+# [3.0.0](https://github.com/ByteBardOrg/AsyncAPI.NET/compare/v2.1.2...v3.0.0) (2026-06-10)
+### Features
+* Complete 3.0.0 support with full backwards and forwards compatibility
+
+### Bug Fixes
+* add `ApplicableVersions` property to validation rules ([#25](https://github.com/ByteBardOrg/AsyncAPI.NET/issues/25)) ([5e4ed51](https://github.com/ByteBardOrg/AsyncAPI.NET/commit/5e4ed51045b97f595d2e4d6287406b227763d43d))
+* small adjustments in deserialization validation ([#29](https://github.com/ByteBardOrg/AsyncAPI.NET/issues/29)) ([eeb9d8f](https://github.com/ByteBardOrg/AsyncAPI.NET/commit/eeb9d8f8aedd811b2fc4c32c692868ff47a00824))
+* fix(avro)!: support named type references (#32) ([310868a](https://github.com/ByteBardOrg/AsyncAPI.NET/commit/310868a6e6cb9d0a4feba3ba0b473c031e1d494e)), closes [#32](https://github.com/ByteBardOrg/AsyncAPI.NET/issues/32)
+
+### BREAKING CHANGES
+* All properties and fields have been updated to match the 3.0.0 spec. 2.x specs fed into the reader will get upgraded in terms of dotnet object model, but can be output as both v2 or v3
+* `AvroMap.Values` now uses `AsyncApiAvroSchema` instead of `AvroPrimitiveType`.
+* refactor: error and warning collection in document reader
+
+Changed how validation errors and warnings are added to the diagnostic collection. Previously, all items from the validation result were iterated over. This change explicitly separates the handling of AsyncApiValidatorError into diagnostic.Errors and AsyncApiValidatorWarning into diagnostic.Warnings, ensuring correct categorization of validation feedback.
+
+* docs: add schema wiki page
+* remove docs file
+
