CHANGELOG.md

 ## 0.0.1
 
 * TODO: Describe initial release.
+## 0.1.5
+The main changes are as following:
+1. The new version do the page jump (URL route) based on the inherited FlutterViewController or Activity. The jump procedure will create new instance of FlutterView, while the old version just reuse the underlying FlutterView
+2. Avoiding keeping and reusing the FlutterView, there is no screenshot and complex attach&detach logical any more. As a result, memory is saved and black or white-screen issue occured in old version all are solved.
+3. This version also solved the app life cycle observation issue, we recommend you to use ContainerLifeCycle observer to listen the app enter background or foreground notification instead of WidgetBinding.
+4. We did some code refactoring, the main logic became more straightforward.
+
+
+### API changes
+From the point of API changes, we did some refactoring as following:
+#### iOS API changes
+1. FlutterBoostPlugin's startFlutterWithPlatform function change its parameter from FlutterViewController to Engine
+2. 
+**Before change**
+```objectivec
+FlutterBoostPlugin
+- (void)startFlutterWithPlatform:(id<FLBPlatform>)platform onStart:(void (^)(FlutterViewController *))callback;
+```
+
+**After change**
+
+```objectivec
+FlutterBoostPlugin2
+- (void)startFlutterWithPlatform:(id<FLB2Platform>)platform
+                         onStart:(void (^)(id<FlutterBinaryMessenger,
+                                           FlutterTextureRegistry,
+                                           FlutterPluginRegistry> engine))callback;
+
+```
+
+2. FLBPlatform protocol removed flutterCanPop、accessibilityEnable and added entryForDart
+**Before change:**
+```objectivec
+@protocol FLBPlatform <NSObject>
+@optional
+//Whether to enable accessibility support. Default value is Yes.
+- (BOOL)accessibilityEnable;
+// flutter模块是否还可以pop
+- (void)flutterCanPop:(BOOL)canpop;
+@required
+- (void)openPage:(NSString *)name
+          params:(NSDictionary *)params
+        animated:(BOOL)animated
+      completion:(void (^)(BOOL finished))completion;
+- (void)closePage:(NSString *)uid
+         animated:(BOOL)animated
+           params:(NSDictionary *)params
+       completion:(void (^)(BOOL finished))completion;
+@end
+```
+**After change:**
+```objectivec
+@protocol FLB2Platform <NSObject>
+@optional
+- (NSString *)entryForDart;
+    
+@required
+- (void)open:(NSString *)url
+   urlParams:(NSDictionary *)urlParams
+        exts:(NSDictionary *)exts
+      completion:(void (^)(BOOL finished))completion;
+- (void)close:(NSString *)uid
+       result:(NSDictionary *)result
+         exts:(NSDictionary *)exts
+   completion:(void (^)(BOOL finished))completion;
+@end
+```
+
+#### Android API changes
+Android mainly changed the IPlatform interface and its implementation.
+It removed following APIs:
+```java
+Activity getMainActivity();
+boolean startActivity(Context context,String url,int requestCode);
+Map getSettings();
+```
+
+And added following APIs:
+
+```java
+void registerPlugins(PluginRegistry registry) 方法
+void openContainer(Context context,String url,Map<String,Object> urlParams,int requestCode,Map<String,Object> exts);
+void closeContainer(IContainerRecord record, Map<String,Object> result, Map<String,Object> exts);
+IFlutterEngineProvider engineProvider();
+int whenEngineStart();
+```

 # FlutterBoost
 A next-generation Flutter-Native hybrid solution. FlutterBoost is a Flutter plugin which enables hybrid integration of Flutter for your existing native apps with minimum efforts.The philosophy of FlutterBoost is to use Flutter as easy as using a WebView. Managing Native pages and Flutter pages at the same time is non-trivial in an existing App. FlutterBoost takes care of page resolution for you. The only thing you need to care about is the name of the page(usually could be an URL).
