9**Change Reason**
10
11In the previous routing table configuration file, only a key of the string type can be configured for the **data** field. The query interface provided by the bundle manager module parses the field value. In this version, this restriction is removed, and the field can be set to a JSON string of any type. The query interface does not parse the field value. Instead, it returns the JSON string, which needs to be parsed by the caller. The type of the **data** field in the query interface is changed from a DataItem array to a string.

13**Change Impact**

15This change is a non-compatible change. The build will fail if you do not change the type of the **data** field in your code.
