 ### Changed
 
+- Source files have been organized into a package hierarchy to accommodate Java projects. The import prefix is `earth.groundctrl.fluent`.
+
 - The Mica workaround for non-AMD GPUs is no longer automatically tested in `FluentApp.onCreateStage`. You can use `Windows.isAmdGpu` to do this check manually. The idea behind this change is to be able to set the required system properties in Java's `main` function, i.e. before the JavaFX runtime is initialized.
 
+### Fixed
+
+- Fixed "Determinate ProgressBar" sample in demo app.
