Oct 1, 2025Monthly summary for 2025-10: Delivered improvements to LMS Sync UX and corrected campaign timing in the code-dot-org repository. The LMS sync feature now uses a tooltip to clarify the disabled state and includes a robust error-handling path to reauthorize Google Classroom when permissions are insufficient, improving reliability and reducing user friction. The Korean campaign start date was corrected to accurately reflect the active period, ensuring campaign data integrity and reporting accuracy.

Aug 1, 2025August 2025 performance snapshot for code-dot-org/code-dot-org focusing on business value, data integrity, and user-facing reliability across Teach and Levelbuilder. Delivered a key database migration to remove the content root type column, enabling a simpler schema and easier maintenance. Executed comprehensive cleanup of content root references, including a cleanup/revert/revert-revert sequence to eliminate stale references and reduce technical debt. Implemented routing and redirect improvements to stabilize navigation and onboarding: added a permanent redirect for single-unit courses and modular sign-in redirect support. Strengthened data integrity with backfills for sections without course data and section course IDs, and aligned course_content/sync_in to use course version while resolving remaining unit.course_version references. Introduced unit group tooling with a new unit group script and canonical URL handling for single-unit courses to improve organization and discoverability.

May 1, 2025May 2025 delivered a focused set of Levelbuilder and modular-course improvements that tighten workflow, performance, and test stability. Key features include an All Courses page for viewing/creating/editing courses, safeguarded unit group management, and a migration toward a modular /courses/ URL structure with nested unit routes. Performance enhancements were achieved via a First Unit optimization to reduce database query counts and ensure proper redirection. In addition, modular course reliability was improved through test stability work, navigation/callback URL fixes, and i18n-related fixes, along with re-enabling shared units where appropriate. These changes collectively improve editing efficiency, data integrity, course lifecycle management, and test reliability, enabling faster deployments and scalable course modularization.
