Core Engine Release 5.5

March 2026

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

API Key Default Values

We now set explicit default values for the description and name fields of the module api_key. This prevents potential null errors when creating or updating an API key.

User License Type

In preparation for simplified role management, such as that of consumer roles, the field "user_license_type" is now visible for each role in the "Role configurations" admin snap-in (patch 5.5.3 and higher).
Please note: A role's license type must be configured in accordance with the contract terms.
