*This release rectifies an issue that was identified in the automated grid transformation process for converting GDA2020 → GDA94 within version 4.6.6.   The transformation logic applied to ORIG and NAT coordinate columns producing incorrect results under specific conditions.   This update resolves the issue and ensures correct coordinate handling and transformation behavior.*

## **Release Notes – Auto Grid Transformation v2.2**

**Issue Summary:**

When performing automated grid transformation from GDA2020 to GDA94, the system incorrectly handled the coordinate values stored in the ORIG and NAT columns.  
The GDA2020 ORIG coordinates were copied directly into the NAT columns as if no transformation occurred.  
This behavior caused NAT coordinates to remain unchanged (still in GDA2020), while being labelled as GDA94, leading to downstream inconsistencies in spatial reporting and grid‑based calculations.

**Resolution:**

The underlying MDS assembly and DDL responsible for grid transformation logic has been corrected.

**Key Fixes:**

- NAT coordinates are now correctly recalculated when transforming from GDA2020 → GDA94.
- ORIG coordinates remain untouched and retain their original GDA2020 values.
- NAT coordinates now correctly store the transformed GDA94 values.
- Grid_ID assignment logic has been updated to ensure correct grid attribution during transformation.
- The transformation workflow now behaves consistently across all grid conversion scenarios.

**Impact:**

- Existing datasets affected by the incorrect transformation may require reprocessing to ensure coordinate accuracy.
- New transformations executed after this update will produce correct NAT coordinate values and grid identifiers.

**Recommendations:**

Users relying on NAT coordinates for spatial analysis, reporting, or downstream automation should:

- Re-run grid transformations for affected records.
- Validate coordinate outputs where GDA2020 → GDA94 conversions were previously applied.
