**Full Changelog**: https://github.com/take-kun/mercapi/compare/v0.3.0...v0.4.0

**BREAKING CHANGE** Dropped support for mapping protocol, i.e. accessing response models properties with `object['key']` will not work anymore. Migrate to `dataclasses.asdict(object)['key']`.

Features
- [dataclasses](https://docs.python.org/3/library/dataclasses.html) support implemented for response objects (#11)
- search results (`SearchResults`) pagination methods (14)
- fetching full item details (`Item`) from seller profile listing (`Items/SellerItem`)

Fixes
- nested lists of `ResponseModel` objects not included in dictionary casting (8)

Fixes
- nested models not included in dictionary casting (5)

Features
- all data model classes (subclasses of `ResponseModel`) implement mapping protocol and can be used as dictionaries

Fixes
- subclasses of `ResponseModel` properly use typed named tuples for lists of properties
