This milestone document outlines the progress made toward releasing the DataTools4Heart (DT4H) Toolbox components into the appropriate software repositories. The toolbox aims to provide a comprehensive, privacy-preserving suite of tools for federated cardiology data analysis, including data ingestion, harmonisation, machine learning, and synthetic data generation, among others. Approximately half of the planned components have been successfully developed and are now available in public or restricted repositories, depending on their maturity.
