# Core Engine Release 4.45
October 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.
# Improvements
- Assign users: Wherever in the system a user can be selected and assigned to an object (e.g., a collection, task, or saved filter), only those users who actually have access to the corresponding module are now displayed for selection.
# Technical Changes & Admin Instructions
# New Query Function: module_access
We have added the new query function hasModuleAccess(<moduleName>), which allows users to be filtered by their access rights to a module:
- Access:
hasModuleAccess(<moduleName>)orhasModuleAccess(<moduleName>) = true - No access:
hasModuleAccess(<moduleName>) = false
The argument <moduleName> supports the following notations: 'file', "file", or file.
This function can be applied to both the user and ce_role modules.
