# Core Engine Release 4.18
September 2024
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
- Loading animation: We have improved the loading animation in the main views of all modules to help users visualize the upcoming objects.
# Solved Bugs
- Fix the error texts of field renderers. They were displayed in warning color instead of error color.
- Fix not displaying the contents of a deleted object in the details pop-up of admin snap-in "Deleted objects"
- Fix not displaying dimension pop-up values of a deleted object in admin snap-in "Deleted objects"
- Fix not displaying a custom primary logo for themes other than the "default" theme
- Fix the renderer validation value option "ce_all_accessible_modules" by replacing it with "ce_all_modules". This avoids errors for users who do not have access to configured modules (e.g. in module Filetransfer).
- Fix not retrieving session embedded properties if the 4ALLPORTAL API URL was not set or not reachable
# How to Get These Improvements
