+### Download dependencies from installApps and installTestApps settings
+
+The DownloadProjectDependencies action now downloads app files from URLs specified in the `installApps` and `installTestApps` settings. Previously, URL validation was done at build time without downloading. Now the files are downloaded upfront, improving error detection and build reliability.
+
 ### Set default values for workflow inputs
 
 The `workflowDefaultInputs` setting now also applies to `workflow_call` inputs when an input with the same name exists for `workflow_dispatch`.
