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
# Version Comparison
Users can now compare two versions of an object, such as an image or a product, to get a quick overview of the differences between two versions. When comparing to the current version, users can also transfer metadata from an archived version to the current version. The "Compare versions" action appears in the toolbox when two versions are selected in the "Versions" tab. This functionality is already familiar from the "Compare objects" feature.
Admin instruction: This feature needs to be enabled for each module and role separately in the role-based module settings (feature permission "Allow version comparison", default: disabled).
# Improvements
- Large search results: We have improved the sorting of search results with more than 15,000 objects. Users can now continue to use the available sort fields and sort order even with high search results.
# Solved Bugs
- Fix missing dimensions when retrieving the object of a PAP connector
- Fix throwing OIS events even when a watermark configuration field changes (now skipped)
- Fix the need to enter a value to enable the 'Is filled' and 'Is not filled' search operators. The input field is now disabled when selecting "Is filled" or "Is not filled".
- Fix unexpected error message e.g. when opening eTicket create popup
