In late 2017, Canvas made its initial release of an updated Gradebook (https://community.canvaslms.com/docs/DOC-13333-canvas-release-new-gradebook). Since that time, Canvas has released a series of updates to ensure stability of this tool and add new features making this new tool comparable to the existing one. As of late 2018/early 2019, Canvas has achieved feature parity between the current and revised gradebook.
UC Berkeley plans to release the new gradebook to bCourses during Summer 2019, pending final confirmation of functionality and feature parity of this revised tool. This gradebook should introduce some new grading features, and improve gradebook loading time in large courses.
