For maintaining an audit trail of metadata changes over time and developing, testing, and releasing projects independently, the recommended development model is:

Package Development: This model supports modular development, allowing developers to create, test, and deploy packages independently. It provides version control and a clear audit trail of changes, ensuring that metadata changes are tracked and managed efficiently.

Independent Projects: Package development allows multiple projects to be developed in parallel without interference, making it ideal for complex environments with multiple ongoing initiatives.

Package development provides the structure and control needed for managing metadata and development processes effectively.
