### Changed
* BREAKING [#186](https://github.com/Dynamoid/Dynamoid/pull/186) Consistent behavior for `Model.where({}).all` (@andrykonchin)

* <= 1.3.x behaviour - find returns nil or smaller array.
* New behaviour - it raises RecordNotFound if one or more records can not be found for the requested ids
* BREAKING [#196](https://github.com/Dynamoid/Dynamoid/pull/196) Return value of `#save` (@andrykonchin)
* <= 1.3.x behaviour - save returns self if model is saved successfully
* New behaviour - it returns true
* [#185](https://github.com/Dynamoid/Dynamoid/pull/185) `where`, finders and friends take into account STI (single table inheritance) now (@andrykonchin)
* query will return items of the model class and all subclasses
* [#190](https://github.com/Dynamoid/Dynamoid/pull/190) Allow passing options to range when defining attributes of the document (@richardhsu)
* Allows for serialized fields and passing the serializer option.
