+## Summary
+This release focuses on enhancing data security and integrity. Additional columns have been masked to further protect sensitive information, and outbound data validation has been strengthened to ensure only records with valid NHS numbers are processed. These changes improve compliance and data quality across the platform.
+
+### Improvements
+- Masked additional columns (`DATE_OF_BIRTH_DAY`, `DATE_OF_DEATH_DAY`) in PERSON_PDS_LATEST, PERSON_PDS_VERSIONED, and PERSON_PDS_VERSIONED_ENTITLED tables to enhance data privacy. *[PR: [#87](https://github.com/NHSISL/LondonDataservices.Transform.OLIDS_Enrichment/pull/87)]*
+  > 🎯 ***Impact:*** Strengthens data protection by ensuring more sensitive fields are consistently masked across key tables.
+
+- Enhanced validation in the NDOO Outbound view to include only records with a valid 10-digit NHS number or a valid hashed NHS number, with support for both production and development/test environments. *[PR: [#88](https://github.com/NHSISL/LondonDataservices.Transform.OLIDS_Enrichment/pull/88)]*
+  > 🎯 ***Impact:*** Improves data quality and compliance by filtering out records with invalid NHS numbers, reducing the risk of processing incorrect or test data in production.

+## Summary
+This release introduces enhanced masking policy governance for NDOO and PDS tables, focusing on schema naming consistency, expanded column coverage, and improved environment-specific policy management. These updates strengthen data privacy controls and ensure that development and production environments are governed more accurately and consistently.
+
+### Improvements
+- Updated masking policy governance for NDOO and PDS tables, including schema renaming to `NDOO_REQUEST`, expanded masking to cover additional columns such as `SK_PATIENT_ID`, and improved environment-specific policy assignment for development and production. Also added a post-hook for adaptive column governance in the project configuration. *[PR: [#89](https://github.com/NHSISL/LondonDataservices.Transform.OLIDS_Enrichment/pull/89)]*
+  > 🎯 ***Impact:*** Ensures more consistent and comprehensive data masking across environments, improving data privacy and governance while reducing manual configuration errors.

+> The below is a summary of the changes since the previous release [v3.0.3](https://github.com/NHSISL/LondonDataservices.Transform.OLIDS_Enrichment/releases/tag/releases%2Fv3.0.3).
+## Summary
+
+This release delivers significant enhancements to the OLIDS Enrichment platform, introducing new data integration layers, improved terminology management, and expanded support for data opt-out governance. Key highlights include the addition of a "Combine" schema for unifying datasets, integration of Local Data Opt-Out (LDOO) alongside National Data Opt-Out (NDOO), and comprehensive updates to concept and mapping tables to ensure referential integrity and historical tracking. Several improvements also standardize table naming and update package dependencies, supporting both EMIS and TPP data sources. These changes collectively strengthen data consistency, governance, and usability for downstream consumers.
+
+### New Features
+
+- Add new SQL views to combine datasets ([#74](https://github.com/NHSISL/LondonDataservices.Transform.OLIDS_Enrichment/pull/74))
+  > ✨ ***Feature:*** Introduces a "Combine" schema with 30 new views to unify EMIS datasets, laying the groundwork for future integration of TPP Primary Care, Community, and Mental Health data. This enables more comprehensive and streamlined data analysis across sources.
+
+- Adding Terminology components ([#93](https://github.com/NHSISL/LondonDataservices.Transform.OLIDS_Enrichment/pull/93))
+  > ✨ ***Feature:*** Adds new terminology objects and updates for UPRN and PDS ingestion, improving the platform's ability to manage and process standardised clinical terminology and supporting more robust data linkage.
+
+- Add Local Data Opt Out (LDOO) model and tests ([#94](https://github.com/NHSISL/LondonDataservices.Transform.OLIDS_Enrichment/pull/94))
+  > ✨ ***Feature:*** Adds support for the Local Data Opt-Out (LDOO) data source, integrates it with existing National Data Opt-Out (NDOO) enrichment, and updates masking and sharing views. This ensures both opt-out types are governed and available for downstream use, with comprehensive unit tests for reliability.
+
+### Improvements
+
+- Concept and Concept Map Updates ([#92](https://github.com/NHSISL/LondonDataservices.Transform.OLIDS_Enrichment/pull/92))
+  > 🎯 ***Impact:*** Adds missing concepts, ensures only current code versions are included, and improves referential integrity between concept and concept_map tables. Introduces historic mapping tracking and new metadata columns, enhancing data accuracy and auditability.
+
+- Mapping table updates for TPP and adding LDOO ([#95](https://github.com/NHSISL/LondonDataservices.Transform.OLIDS_Enrichment/pull/95))
+  > 🎯 ***Impact:*** Updates mapping tables to support TPP Community and Mental Health ingestion and incorporates LDOO, broadening the scope of data ingestion and improving data governance.
+
+- Update package revisions for EMIS_OLIDS and OLIDS_Share ([#96](https://github.com/NHSISL/LondonDataservices.Transform.OLIDS_Enrichment/pull/96))
+  > 🎯 ***Impact:*** Updates package dependencies to the latest revisions, ensuring compatibility and access to recent features and fixes.
+
+### Bug Fixes
+
+- Standardize table names in masking policies for TPP data ([#91](https://github.com/NHSISL/LondonDataservices.Transform.OLIDS_Enrichment/pull/91))
+  > 🐞 ***Fix:*** Updates masking policies to use standardized table names for TPP data, aligning them with EMIS naming conventions and reducing the risk of misconfiguration or data access issues.
