eCBA Release notes

Versioning is a process of tracking changes to a database or software over time, allowing users to understand how the database has evolved and to easily roll back changes if necessary. As changes are made to the UI/UX of the database, it will be documented here in the release notes and this will include a brief description of the change, and the date it was made. We also use GitHub as the version control system to manage changes to the database by our developers. This allows us to track changes over time, roll back changes if necessary, and collaborate with others on the database.

Updated eCBA video walkthroughs

MinorOperational pre-release

Based on user feedback, we've enhanced our video walkthrough content by restructuring it into three focused segments for better user experience. The updated series includes: (1) 'Introduction to eCBA' providing an overview of the application, (2) 'The eCBA in Practice' guiding users through project setup and screening processes, and (3) 'Interpreting Your Results' helping users understand and analyze their screened variant outcomes. This segmented approach makes the learning process more manageable and allows users to easily find specific guidance when needed.
