• The DBAPI v2.0 compliance and Enhanced Pythonic Features sections have been moved and improved for clarity, and the example code now demonstrates a realistic query using Entra ID Interactive authentication.

Roadmap Updates:

• The ROADMAP.md file has been replaced with a concise feature matrix table, showing planned and in-progress features with estimated timelines, instead of a narrative roadmap.
