Hi everybody,

We updated our module repositories with the latest libraries and functionalities.

Central Repository 3.68.0

UI

The MWT library 3.7.0 and 3.7.1 improve layout, rendering, benchmarks tooling and add new hooks in the widget lifecycle listener, and the Widget library 5.6.0 and 5.6.1 add a method in List to track its orientation.

  • “ej.library.ui.mwt” new version added (3.7.1)
    • Add setX() and setY() methods in Widget.
    • Optimize layout and rendering for widgets (or containers) with default outlines and dimension to reduce Java heap usage and minimize computations.
    • Add widget and animation lifecycle listeners for debug.
    • Add an utility to benchmark animations.
    • Add additional traces for easier profiling.
  • “ej.library.ui.widget” new version added (5.6.1)
    • Add List.isHorizontal() method to simplify retrieval of orientation.

NET

The ECOM-WIFI 2.1 Test Suite 0.2.2 fixes its module version.

MicroAI

The MicroAI ecosystem gets a coordinated update to 2.3.0. The MicroAI API introduces a configurable MicroAI heap, the MicroAI Mock aligns with the new API, and the brand-new MicroAI Test Suite adds a property to configure the memory pool size and migrates to the MicroEJ Library plugin.
