MicroEJ Repositories October 2026 Second Update

Good news everyone,

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

Central Repository 4.2.0

UI

In UI Pack 14.5.5, the simulator can run without its window, for example on a CI agent: see the ej.fp.headless option (and the Image and Font Generators no longer fail on a machine without an X server). The Low Level API adds the LLUI_DISPLAY_FORMAT and LLUI_DISPLAY_BPP defines, so a BSP can check its display format at compile time. See the migration guide before you upgrade.

VG

In VG Pack 1.8.3, the text measure and the text drawing now respect the MicroVG API specification, on the device and on the simulator; existing layouts may therefore move by a few pixels: see the migration guide.

Developer Repository

UI

The Front Panel widgets (whose Display widget now supports the headless mode) and the DMA2D, VGLite and NemaGFX Abstraction Layers are compatible with UI Pack 14.5.5.

VG

The VGLite and NemaVG Abstraction Layers and the FreeType and HarfBuzz C modules are compatible with VG Pack 1.8.3 and fix several issues.

The Central and Developer Repositories are accessible by default in MICROEJ SDK and provide libraries to enrich your applications and help development. Please consult our Javadoc for more information.

Happy coding!
