2.39 Upgrade Notes¶

Please ensure you have read the upgrade notes from the PREVIOUS RELEASE, if upgrading from an earlier version

Web Apps¶

The previous data approval Struts-based web module is removed, and superseded by the React-based data approval web app.

Tracker¶

Relationships are now soft-deletable entities. This means that when they are deleted, they are still in the database but they are still used in validations. So if an import is trying to reference a soft-deleted relationship, the importer will return an error.
In previous versions Relationships were identified by their UID or by a combination of Relationship Type, from field and to field. From 2.39 Relationships are only identified by their UID. This is causing a potential breaking change as earlier a payload with a Relationship without a specified UID could be imported multiple times without errors (just a warning that updating the relationship was not possible), while now the import is throwing an error stating that a Relationship of the same type and linking the same entities already exists.

API¶

Metadata attribute validation: Validation of metadata attributes will be executed when saving objects with attribute values in the maintenance app. Validation rules are now based on the Attribute.ValueType. Most of those rules are straightforward. For instance value type "number" will only accept digits. On the other hand, "phone number" has a regular expression validation rule "^[0-9+\$\$#\\.\\s\\/ext-]{6,50}$". As a result of this new validation feature, you might get errors when editing metadata objects which now have invalid attribute values. In that case please update the values and save the object.
Old tracker APIs deprecated: The old tracker API endpoints for importing tracked and event data are now deprecated. We encourage developers of apps and extensions do transition over to the new endpoints. Server-to-server sync will continue to use the old API endpoints. This includes all API calls which are made with the import strategy SYNC. Deprecated API endpoints (except SYNC) are:
```
- /api/trackedEntityInstances
- /api/enrollments
- /api/events
```
These endpoints have been replaced with the new tracker endpoint:
```
- /api/tracker/
```

Deprecated endpoints have been removed: (see deprecated-features )
- XML support in metadata APIs as well as in metadata import and export has been removed.
- The POST /api/dataAnalysis/stdDevOutlier and POST /api/dataAnalysis/minMaxOutlier API endpoints are removed. These endpoints are superseded by the /api/outlierDetection API which offers higher performance and more sophisticated outlier detection.
- The POST /api/dataAnalysis/followup API endpoint for reading follow-up data values is removed. This endpoint is superseded by the GET /api/dataAnalysis/followup API endpoint.
- The type field in the /api/analytcs API endpoint metadata > headers response is removed. Instead use the valueType field.
