# HOOPS Communicator 2024.4.0

HOOPS Communicator 2024.4.0 is based on HOOPS Visualize 2024.4.0, HOOPS Exchange 2024.4.0, and HOOPS Publish 2024.4.0.

## Enhancements

ESM

HOOPS Communicator WebViewer follows new ESM standards and can now load Javascript via ESM. With release 2024.4.0, the beta period ends and official support starts. Using ESM is recommended for all new developements. Tech Soft 3D also encourages existing integrations of the WebViewer API to migrate to ESM in order to fully benefit of all future development in the WebViewer. Details are available here. We also have a migration guide.

## Functional Changes

Path Changes

ESM libraries have been relocated from COMMUNICATOR_INSTALL_DIR/web_viewer/esm/ to the COMMUNICATOR_INSTALL_DIR/web_viewer directory. Non-ESM libraries have been relocated to COMMUNICATOR_INSTALL_DIR/web_viewer/deprecated.

## Deprecation

Legacy version of WebViewer IIFE API is deprecated. Newer versions are provided with identical API following the standard ESM, UMD, and IIFE. `Communicator.SubentityProperties` is now deprecated and hidden.

## API Changes

New API to compensate for deprecation of `Communicator.SubentityProperties`:

- `Utils::isLineElement(prop: object): boolean`
- `Utils.isCircleElement(prop: object): boolean`
- `Utils.isOtherEdgeElement(prop: object): boolean`
- `Utils.isPlaneElement(prop: object): boolean`
- `Utils.isFace(prop: object): boolean`
