# Enhancements

## **Stable `hash_id` Introduced for HELLO\_CNAR and HELLO\_CUSTOM SoT (Source of Truth)**

To address the non-persistent nature of `cnar_id`, which changes across releases even for the same address, this version introduces a new `hash_id` field as a stable and unique identifier.\
The `hash_id` ensures consistent identification of address records across releases, improving data traceability and integration reliability for systems consuming the `HELLO_CNAR` and `HELLO_CUSTOM` SoT (Source of Truth).

## **Province Field Included in Address Search for Custom Address Data Framework**

In version 3.1, the custom framework was introduced to support flexible address indexing and validation. However, the initial implementation did not include the **province** field in the `indexed_content`, which led to failed searches when province data was provided as input.

Version 3.2 resolves this issue by including the province field in the `indexed_content`—the internal representation of indexed address fields used for search and validation. This enhancement ensures more accurate and complete address matching when province information is part of the query.

## **Integrated Build Script for HELLO\_CUSTOM  SoT (Source of Truth) in Harmony Package**

Previously, building the `HELLO_CUSTOM` SoT (introduced in version [3.1.0](/harmony-suite/release-notes/version-3.1.0.md)) required a separate tool package. In this release, the build process has been streamlined: the build script is now included directly within the Harmony package under the `tools` folder.

Users can now build the index using a simplified command such as:

```
build_hello_index.bat plugin/custom/beans.xml TEST
```

Scripts are provided for both Windows (`.bat`) and Linux (`.sh`) environments, making the setup more accessible and reducing the need for external dependencies.
