#### 3.0.0-2 Data Binding Changes The following changes have been made:
- Bugfix: Bindable properties of widgets were wrong displayed in SceneComposer. The problem has been solved, by replacing the function bound global string variable with a function bound global map that maps the meta info property instance to the corresponding editor string. - Bugfix: Data binding was no longer working correctly on target builds with O2 optimization enabled. For this, Courier::DataBindingPrivate::DataItemDescriptor structure was modified.
#### 3.0.0-3 Visualization Changes The following changes have been made:
- Composite Group support was added.

For this, [Courier::ViewHandler::SetFontStoreProviderCallback](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_handler.html#a7747f74f80b57fd376b13f942d927009) and [Courier::ViewHandler::GetDefaultFontStore](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_handler.html#a99a7c93fcae6feb74fa279b250181ab8) were added. - Bugfix: Fix added for animation invalidate mechanism to correctly invalidate related scenes. For this, the following has been modified: - The enum [Courier::AnimationInvalidator::Setter](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_animation_invalidator.html#af1757d61530f8617d19c127ebdb01a58) has been modified; - Scene3DPtrVector and Scene2DPtrVector typedefs were removed. - Bugfix: interface changed for [Courier::ViewHandler::Init()](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_handler.html#aa48e5f58172e21058b426313076f068a) method to accept every kind of [Candera::AssetConfig](http://dev.doc.cgistudio.at/APILINK/class_candera_1_1_asset_config.html "Asset configuration that encapsulates various asset repositories Custom AssetConfig classes can be de..."). For this, the following has been modified: - *assetConfiguration* parameter type changed from [Courier::AssetConfiguration](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_asset_configuration.html)\* to [Candera::AssetConfig](http://dev.doc.cgistudio.at/APILINK/class_candera_1_1_asset_config.html "Asset configuration that encapsulates various asset repositories Custom AssetConfig classes can be de...")\* for [Courier::AssetAccessor::Init](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_asset_accessor.html#a3a9167051a8e1f79cb788b202d9d2e5e) and IViewHandler::Init method. - Bugfix: Fixed wrong touch input handling on overlay surfaces. For this, the following has been modified: - *pointerId* and *sourceId* parameters have been added to [Courier::TouchInfo](http://dev.doc.cgistudio.at/APILINK/struct_courier_1_1_touch_info.html) constructor. - Bugfix: Fixed issue related to wrong loading of scene's content for [Courier::LoadReqMsg](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_load_req_msg.html). For this, the following has been modified: - The [Courier::LoadReqMsg](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_load_req_msg.html) will provide the same behavior as before to keep backward compatibility. A new [Courier::TryLoadReqMsg](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_try_load_req_msg.html) and [Courier::TryAsyncLoadReqMsg](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_try_async_load_req_msg.html) were introduces. [Courier::TryLoadReqMsg](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_try_load_req_msg.html) creates the render target if the layer is not already used. Otherwise nothing is done for the render target. Also, [Courier::TryLoadReqMsg](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_try_load_req_msg.html) tries to upload the scene (this may fail if there is currently no EGL context available - in this case a normal [Courier::LoadReqMsg](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_load_req_msg.html) should be sent before activating the view). The new [Courier::TryAsyncLoadReqMsg](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_try_async_load_req_msg.html) will have the same behavior as [Courier::TryLoadReqMsg](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_try_load_req_msg.html) after the scene context if fully loaded; - A new *forceEnable* parameter has been added to [Courier::Renderer::EnableLayer](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_renderer.html#ac9666429200a0206d45a5bfac018ca72) method; - A new *forceUpload* parameter has been added to [Courier::View::LoadContent](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view.html#a85d92339f636384dd0de6304e1f12a2c), [Courier::ViewContainer::LoadContent](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_container.html#a5a441a6a19c3384f836402d7fce13dea), Courier::ViewHandler::SetCurrentLoadingViewScene, [Courier::ViewScene::PartialLoad](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_scene.html#aa5948a3074888d610b5fe49b4590fc03), [Courier::ViewScene::AsyncLoadContent](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_scene.html#aaa661133250c429fa5b72c2e4543c304), [Courier::ViewScene2D::LoadContent](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_scene2_d.html#aaa170676e8d0c104d8a936a43ede55ad), [Courier::ViewScene2D::PartialLoad](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_scene2_d.html#a9f6b89253e362eca3d5ff7c7b6222f77) and [Courier::ViewScene2D::AsyncLoadContent](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_scene2_d.html#a272dc00207c0d5ee2f5bac8e4ca86224), [Courier::ViewScene3D::LoadContent](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_scene3_d.html#ad0c1cdafc4452c9a8a8f10ec355cf503), [Courier::ViewScene3D::PartialLoad](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_scene3_d.html#a6814d08ab6613216df1cdce5f30a0145) and [Courier::ViewScene3D::AsyncLoadContent](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_scene3_d.html#aa06f66a32764a69a2827bc6268fbe5c4) methods. - Bugfix: No proper clean was done when active transitions received [Courier::ShutdownMsg](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_shutdown_msg.html) message. [Courier::TransitionHandler::Finalize](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_transition_handler.html#a26ea30a1d14df8102a2a0e14b9c50bb2) method has been added. This method will first finish active transitions and second destroy all created transitions to bring the transition handler into a finalized state. The [Courier::TransitionHandler::Finalize](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_transition_handler.html#a26ea30a1d14df8102a2a0e14b9c50bb2) method will finalize the [Courier::TransitionHandler](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_transition_handler.html) (if set), stop all animations and finalize the views. Handling of transition errors has also been added. For this, [Courier::Transition::TransitionError](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_transition.html#a4b9ea742e375e23d8be6f753a1563245) enum, [Courier::Transition::SetLastTransitionError](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_transition.html#ae9ecee210e99963887886906e17fd77f) method and [Courier::Transition::GetLastTransitionError](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_transition.html#a46b2bb1cf67ccd907ae76a7731d38ad1) method were introduced. - Bugfix: Wrong dependent views' invalidation. The new interface allows to add dependency views to another view for one camera or for all cameras using [Courier::View::AddInvalidationDependency](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view.html#ada3ff0817050b58c1c39e6aa59cb06d1) method. To remove the dependency [Courier::View::RemoveInvalidationDependency](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view.html#a4e53f67e0b2a76d9ac3e498fc6fad1db) can be used for one camera dependency or for all camera dependencies (it always has to be called in a symmetric way to the Add call). Also, [Courier::View::GetFirstInvalidationDependency](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view.html#a3c70b12fbb995c827b9e0af523612163) was introduced. - Bugfix: no means to retrieve an animation player for a given animation ID. For this [Courier::ViewHandler::GetAnimationPlayer](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_handler.html#a696c09d4550ced831f7b539ab1f9f936) was made public. - Bugfix: Wrong sorting of widgets' vector. The default behavior can be changed by calling the new [Courier::ViewScene::SetWidgetSortingStrategy](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_scene.html#a190dd404e88488a942292286005ac982 "Set the strategy for the order in which widgets are processed. By default and for backward compatibil...") method. [Courier::ViewScene::GetWidgetSortingStrategy](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_scene.html#a9de03e5428b8d909435c0c8293ac5510) returns the current set strategy. - Bugfix: Too long processing time for [Courier::ViewReqMsg](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_req_msg.html). For this, *initContent* parameter was added to [Courier::ViewReqMsg](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_view_req_msg.html) message for Create and CreateAll actions. This member should be set to false to delay the initialization of the scene from the first loading of the scene.
#### 3.0.0-4 AddOns Changes The following changes have been made:
- Bugfix: Fixed render block issue due to Wayland input handler. For this, Courier::InputHandling::WaylandContext::GetEventQueue method was added; - Bugfix: [Courier::TouchHandling::TouchSession::GetFrameworkWidgets()](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_touch_handling_1_1_touch_session.html#a73c4ea0558f4523d55863cab99e0371e) not accessible for derived classes. To fix this, [Courier::TouchHandling::TouchSession::GetFrameworkWidgets()](http://dev.doc.cgistudio.at/APILINK/class_courier_1_1_touch_handling_1_1_touch_session.html#a73c4ea0558f4523d55863cab99e0371e) was moved in the protected area; - Bugfix: TouchSession is not working. For this, the down state management was replaced with a more dynamic approach that also considers non-linear source Ids. cCOURIER\_DEFAULT\_MAX\_TOUCHPOINTER\_COUNT was set to 10 in Courier::TouchHandling class and Courier::TouchHandling::TouchSessionBase::InvalidSourceId const was declared to indicate a invalid surface Id.
