 # CHANGELOG

+## 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
+* Fixed unneeded reuse of singletons in collaborating containers. 
+  Containers now first attempt to autowire components and fallback to collaboration when it fails.  
+  [#169](https://github.com/AliSoftware/Dip/issues/169), [@ilyapuchka](https://github.com/ilyapuchka)
+
+## 5.1
+
+* Dropped Swift 2.3 support.  
+  [#150](https://github.com/AliSoftware/Dip/issues/150), [@ilyapuchka](https://github.com/ilyapuchka)
+* Added custom logging function.  
+  [#146](https://github.com/AliSoftware/Dip/issues/146), [@Pr0Ger](https://github.com/Pr0Ger)
+  
+#### Fixed
+
+* Fixed Swift 3.1 warnings.  
+  [#145](https://github.com/AliSoftware/Dip/issues/145), [@DenHeadless](https://github.com/DenHeadless)
+* Fixed collaboration shared references.  
+  [#151](https://github.com/AliSoftware/Dip/issues/151), [@ilyapuchka](https://github.com/ilyapuchka)
+* Fixed autowiring when using tags.  
+  [#154](https://github.com/AliSoftware/Dip/issues/154), [@ilyapuchka](https://github.com/ilyapuchka)
+
+## 5.0.4
+
+#### Fixed
+
+* Fixed broken compatibility for Swift 2.3 API in `resolve(tag:arguments:)` method.  
+  [#135](https://github.com/AliSoftware/Dip/issues/135), [@ilyapuchka](https://github.com/ilyapuchka)
+  
 ## 5.0.3

 * Added Swift 2.3 compatibility. `swift2.3` brunch is no longer maintained.

 Dependency Injection is a pattern (more precisely - a set of patterns) as well as a singleton. And any pattern can be abused. DI can be used in a [wrong way]((http://www.loosecouplings.com/2011/01/dependency-injection-using-di-container.html)), container can easily become a service locator. You should carefully decide when to use DI, you should not inject everything and everywhere and define a protocol for every single class you use. For every tool there is a right time and the same way as singleton can harm you the same way DI and protocols abuse can make your code unnececerry complex.
