+## Test Insights Dashboard
+
+The test insights dashboard helps you track student performance and identify common issues across submissions. Access it from the assignment page to view:
+
+### Error Explorer
+
+View and analyze test failures across all student submissions:
+
+- **Error grouping**: Automatically groups similar test failures together
+- **Affected students**: See which students are experiencing each error
+- **Email export**: Copy affected students' email addresses for bulk communication
+- **Global error pins**: Pin important errors to track them across assignments
+
+### Regrade Workflow
+
+Launch targeted regrades directly from the error explorer:
+
+1. **Select errors**: Choose which error groups need regrading
+2. **Preselect submissions**: The autograder page automatically preselects affected submissions
+3. **Regrade dialog**: Choose between:
+   - Specific commits from the repository history
+   - Manual SHA entry for precise version control
+4. **Auto-promote**: Optionally promote the regrade results automatically
+
+This workflow streamlines the process of fixing grading issues and re-evaluating student work without manual submission selection.

 Lastly, you can choose to enforce that graders are **not** assigned to the same submission as they were on a prior assignment or rubric. This feature is useful to assign meta-graders, where the meta-grader is a different grader than the one who graded the submission.
 
 You will be able to preview the assignments before creating them, and can manually tweak them through the drag-and-drop interface.

+## Grading Status Dashboard
+
+The grading status dashboard provides a comprehensive overview of grading progress for an assignment. Access it from the assignment page to monitor:
+
+- **Overall completion**: Track how many submissions have been graded
+- **Per-grader progress**: See individual grader workload and completion rates
+- **Rubric part breakdown**: Monitor progress on specific rubric components
+- **Due date tracking**: Identify overdue grading tasks
+- **Bottleneck identification**: Quickly spot where grading is falling behind
+
+This dashboard helps instructors ensure grading stays on track and identify when intervention or reassignment is needed.

 Each token can be exchanged for a 24-hour extension, but the extension must be requested before the student's original due date.
 
 Instructors and graders can also manually grant extensions to students, and can view all extensions granted to a student. This is done in the assignment configuration under "Due Date Exceptions".
+
+### Extension Date Picker
+
+When granting manual extensions, instructors can now choose the extended due date directly using a date picker interface, rather than entering extension hours and minutes. This makes it easier to:
+
+- Set precise extension deadlines
+- Avoid calculation errors when determining extension duration
+- Quickly grant extensions to specific dates (e.g., "extend until next Monday")
+
+## Assignment Leaderboard
+
+Assignments can include an optional leaderboard feature that displays student rankings based on performance metrics:
+
+- **Configurable visibility**: Choose whether to show or hide the leaderboard
+- **Less cluttering option**: Make the leaderboard less prominent in the UI
+- **Performance tracking**: Display rankings based on scores or custom metrics
+- **Automatic updates**: Leaderboard refreshes as submissions are graded
+
+The leaderboard feature can encourage friendly competition while remaining optional for courses that prefer not to emphasize rankings.
+
+## Assignment Security Dashboard
+
+The security dashboard helps instructors monitor and prevent academic integrity issues:
+
+- **Anomaly detection**: Identify unusual submission patterns
+- **Collaboration analysis**: Detect potential unauthorized collaboration
+- **Submission timing**: Track when students submit relative to deadlines
+- **Access patterns**: Monitor repository access and commit history
+
+Access the security dashboard from the assignment page to review potential concerns and investigate suspicious activity.

+## Rerunning the Autograder
+
+When testing or debugging grading issues, you can rerun the autograder on any submission:
+
+1. **Reuse submission**: The rerun uses the same submission record rather than creating a new one
+2. **Select grader version**: Choose which version of the grader to use for the rerun:

+   - Select a specific commit from the grader repository history
