4 Commits • 1 Features
Oct 1, 2025October 2025 monthly summary for instructure/canvas-lms. Delivered a new Peer Review Overrides API enabling creation and application of peer review overrides via the Assignment API, including section-specific and student-specific due dates. Hardened the peer review subsystem by preventing unsupported Sub Assignments and by simplifying differentiation tag enablement logic to reflect account-level settings, addressing test reliability. Fixed the Bulk Assignment Edit UI label issue in the stacked layout and added tests to verify label correctness across stacked and fixed layouts. These changes improve instructor scheduling flexibility, system robustness, and UI clarity, supported by expanded test coverage.
