## [Unreleased]
88

9-
* Nothing
9+
This release includes changes to some interfaces. This is a breaking change if you use these interfaces in your own code.
10+
11+
### Added
12+
13+
* Added `OneRelationInterface` and `ManyRelationInterface` to differentiate between singular and plural relations.
14+
15+
### Changed
16+
17+
* Moved `setType` and `getType` from `RelationInterface` to a separate interface; `TypedRelationInterface`.
18+
* Added type hints to `ItemInterface::setRelation`.
19+
* Added return type hint to `Item::hasAttribute`.
20+
21+
### Removed
22+
23+
* Removed `RelationInterface` in favor of `OneRelationInterface` and `ManyRelationInterface`.
24+
* Removed `setId` and `getId` from `HasOneRelation` and `MorphToRelation`. These operations should be performed on the included item.
25+
* Removed `setType` and `getType` from morph relations. Use regular relations if you want to set the type.
