# Enhancements

## G-NAF Enhanced Postcode Allocation

Enhanced locality‑level postcode allocation in G‑NAF to ensure it more accurately reflects and respects the raw postcode values present in the source dataset.

## CNARGeocode GROUP Matching – Accented vs. De‑accented Input

Matching logic has been updated to ensure **accent‑insensitive processing**, allowing GROUP matches to be returned regardless of whether the input is accented or de‑accented.

## Addition of `rdNumber` to CUSTOM Response

The `rdNumber` field is now included in the CUSTOM response payload, ensuring attribute parity with CNAR and enabling consumers to access this value directly.

## CNAR PDPChangedItem Scope – Missing Postcode & Standardisation Changes

The PDPChangedItem scope for CNAR has been updated to correctly capture and report **postcode updates** and **all relevant standardisation changes**, ensuring full visibility of field-level modifications.

## **Security Enhancements**

A series of security vulnerabilities identified through assessments have been addressed in this release. These fixes improve system resilience, mitigate potential attack vectors, and ensure compliance with the latest security requirements.

## Deprecated Modules

As part of ongoing platform optimisation, several legacy modules have been **deprecated** in this release. These components were phased in this version to streamline the product architecture and support a more modern, maintainable codebase.
