The following chapters describe the changes to perform in the application according the MicroEJ UI Pack used to build the MicroEJ Platform.

From 12.x to 13.x¶

Update ej.api#microui dependency to the latest available version 3.x.
Add ej.api#drawing dependency.

   <dependency org="ej.api" name="drawing" rev="1.0.3"/>
</dependencies>

From 10.x to 12.x¶

In MicroEJ application launcher > Configuration tab > MicroUI: check Use Flying Images when the application is using the flying images (property com.microej.library.microui.flyingimage.enabled).
