 ### 0.8.0 [BREAKING CHANGES]
 
+- [class-transformer](https://github.com/typestack/class-transformer) and [class-validator](https://github.com/typestack/class-validator) are now peer dependencies.
+
 #### Features
 
 - extract generic `@Session()` deocorator into `@SessionParam()` and `@Session()` (ref [#335][#348][#407])
 - restore/introduce `@QueryParams()` and `@Params()` missing decorators options (ref [#289][#289])
 - normalize param object properties (for "queries", "headers", "params" and "cookies"), with this change you can easily validate query/path params using `class-validator` (ref [#289][#289])
 - improved params normalization, converting to primitive types is now more strict and can throw ParamNormalizationError (e.g. when number is expected but an invalid string (NaN) has been received) (ref [#289][#289])
