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.

June 25 2026|v2.9.7

Unsaved Changes Protection

Major

Project forms are now protected against accidental data loss. If the user moves away from a form with unsaved edits — stepping between sections, switching tabs or projects, or closing the browser tab — the application prompts you to save first, continue without saving, or stay on the page. Saving from the prompt validates and stores your work before taking you to your destination. Save feedback has also been improved, with a clear notification if a save does not complete.

June 2 2026|v2.9.3

Project Cloning

MajorPatch

Users can now clone an existing project directly from their projects list. The clone workflow creates a new project under the current user account - prefixed with the copied title with [clone]. Uploaded project documents are not copied across to the new project. General project action feedback has also been improved with clearer success and error notifications.

May 27 2026|v2.9.1

Localized Form Guidance

Minor

Locale-based language content has been added to all remaining info modals across the application forms. These components are now dynamically built from our shared key tree structure making future updates easier to maintain across all supported languages.
