 # CHANGELOG

+## Develop
+
+## 7.1.1
+
+* Fixed using `StoryboardInstantiatable` with SPM  ([#233](https://github.com/AliSoftware/Dip/pull/233)).
+
+## 7.1.0
+
+* You can now use a shorthand syntax for resolving a single property using a key path, i.e. `resolvingProperty(\.value)`.
+* Swift 5.0 support ([#224](https://github.com/AliSoftware/Dip/pull/224)).
+* Fixed resolving nested types with the same local names ([#221](https://github.com/AliSoftware/Dip/pull/221)).
+* `@Injected` and `@IntectedWeak` property wrappers ([#225](https://github.com/AliSoftware/Dip/pull/225)).
+* Thread safety can be disabled on container level.
+
+## 7.0.1
+
+* Added a workaround for Swift 4.2 regression related to retaining weak properties ([#214](https://github.com/AliSoftware/Dip/issues/214)).
+  For that auto-injection can be disabled or enabled for the whole container or individula registrations.
+
+## 7.0.0
+
+* Swift 4.2 support.
+* Fixed some issues when reusing instances previously resolved as optionals.
+* Dip-UI is now part of Dip.
+
+## 6.1
+
+* Swift 4.1 support.
+* Fixed crashes resolving singletons using collaborating containers.
+  [#179](https://github.com/AliSoftware/Dip/pull/179), [@trimmurrti](https://github.com/trimmurrti)
+  [#182](https://github.com/AliSoftware/Dip/pull/182), [@tapsandswipes](https://github.com/tapsandswipes)
+
 ## 6.0

 * Swift 4 support
