 ## Helm Chart Changes
 
 This release introduces more important changes to the Helm chart configuration:
 
 ### Breaking changes
 
-#### Merge of MobSF parsers
+#### Tags
 
-Mobsfscan Scan" has been merged into the "MobSF Scan" parser. The "Mobsfscan Scan" scan_type has been retained to keep deduplication working for existing Tests, but users are encouraged to move to the "MobSF Scan" scan_type.
+`tag` and `repositoryPrefix` fields have been deprecated. Currently, image tags used in containers are derived by default from the `appVersion` defined in the Chart.  
+This behavior can be overridden by setting the `tag` value in `images.django` and `images.nginx`.  
+If fine-tuning is necessary, each container’s image value can also be customized individually (`celery.beat.image`, `celery.worker.image`, `django.nginx.image`, `django.uwsgi.image`, `initializer.image`, and `dbMigrationChecker.image`).  
+Digest pinning is now supported as well.
