 ## Changelog
 
+### 1.10
+
+Move creation of guice injector from `onConfigurationRead()` to `onApplicationStart()`.
+We found that method `onConfigurationRead()` can be called many times during application lifetime (on every application.conf change).
+It causes creating multiple instances of guice injector, thus causing memory leaks.
+
+### 1.9
+
+  * Added guava 23.0 dependency (Guice actually doesn't work without it)
+  * upgrade to play 1.5.1 (which adds methods Injector.setBeanSource() and automatically injects controllers' instances)
+
+### 1.8
+
+  * upgrade to play 1.5
+
+### 1.7
+
+  * create request.controllerInstance even if action method is static
+
+### 1.6
+
+  * upgrade guice to 4.1.0 and include multibindings
+
 ### 1.5
 
   * support injecting of non-static dependencies into controllers
