Core Engine Release 4.43

September 2025

We upgraded! What's new? Learn more about new features, technical changes and solved bugs in 4App Core Engine.
Note on upgrading: If you skip a version when upgrading, check all release and patch notes in between for important information. They apply cumulative.
Note on individualization: If your 4ALLPORTAL is highly customized or if you installed individual apps, please contact your implementation partner before upgrading. We recommend checking your custom contents, especially layouts and object renderers, carefully after an upgrade.

Technical Changes & Admin Instructions

Extendable Lists in CEObjectListItemRenderer

The existing component, CEObjectListItemRenderer, has been enhanced with the extendedContent parameter to support expandable panels in lists. This allows users to access extra content without having to leave the current view. The configuration supports subpanels and object renderers (both read-only). It automatically provides an 'Expand' button next to a list entry as soon as the extendedContent configuration contains items. To ensure optimal performance, the extendable content is only loaded when a panel is opened.

Search for Versions

We have implemented the option to configure a version search. Configurators can now use relation fields `version_parent_file.title` and `version_parent_file.metadata` to search for a version's title and/or a version's metadata.
Further information: For requirements and a configuration guide, refer to the documentation How to Configure a Version Search.

New Metadata Mapping Set Instructions

We have added two new set_instructions for workflow action "metadata mapping":

• list_add_before[:item|:json:content] to insert a value immediately before a referenced list entry
• list_add_after[:item|:json:content] to insert a value immediately after a referenced list entry

The optional suffixes item and json:content can be added to both instructions (e.g. list_add_after:json:{"id":"870de9b7-b65d-4eef-a328-b21b182592c7","link_module":"file"}).
Please note: Both instructions are additive and do not change the existing behavior of other list operations.
What to do: Existing set scripts keep working unchanged. Use these new instructions where you previously had to rebuild lists manually.

Unified Magick Command

We now use the unified magick command (ImageMagick 7+) instead of convert, identify, compare and identify.
