Core Engine Release 5.4

February 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.

New Features and Improvements

Dimensions Admin Snap-in

In the new Dimensions admin snap-in (via General system configurations > System settings), you can now create new and manage existing dimensions, e.g. by adding or removing dimension values. Configurations formerly made in the file system can now be made here.

Please note: Changes to existing dimensions should be carefully considered in advance, as they may affect existing metadata and configurations, such as workflows.
Further information: Dimensions documentation

4APQL: Support for Functions

We have added support for the following functions in 4APQL: currentUser, currentRole, getObject. They are helpful, for example, when a reference to the current user is required.

Technical Changes & Admin Instructions

Update of Embedded Tools

We have updated the following embedded tools:

• ImageMagick: version 7.1.2-13
• FFmpeg: version 8.0.1
• ExifTool: version 13.50
• Ghostscript: version 10.06.0

Metric Changes

• The following metrics have been marked for removal:
  • 4allportal_daily_active_user
  • 4allportal_monthly_active_user
  • 4allportal_active_user_all_time
  • 4allportal_login_attempts
  • 4allportal_login_attempts_successful
• The metric 4allportal_average_session_duration has been removed.
• The metric 4allportal_number_slow_queries has been replaced by 4allportal_core_slow_queries.

SearchActor: Additional Sort Fields

You can now add additional sort fields to further control the sorting of a search list. This is particularly helpful when there are many identical entries in a result list, such as project name or last name. Based on the additional sort fields, you can control how identical results are displayed, e.g. in descending order by creation date or first name. The additional sort fields work in the background and need to be added to a layout. Further Information: SearchActor Parameters
