• Rails upgraded to 6.1.7.6
• Table migrations needed due to schema changes NOTE This might take a while for existing deployments due to the migration in #2024

• [#1983] Attachments now have a "release at" date rather than a released flag. Any existing unreleased attachments will have their "release at" date set to 1 year in the future.
• [#2014] Removal of grading deadline
• [#2023] ActiveStorage is now used for attachments. They are stored within the storage subdirectory.
• [#1987] Refactor Assessment name rules, remove config file requirement

  • For instructors: You can now create assessments with folder names that include hyphens, capitalization, and alphanumeric characters as long as the folder name begins with a alphabetical character. Config files no longer need to be included in an assessment folder for a successful import.
  • More examples are available at https://docs.autolabproject.com/lab/#assessment-naming-rules

cp config/lti_settings.yml.template config/lti_settings.yml

New Features

LTI Integration

#1635, #1649, #1657, #1678 Autolab now supports roster syncing with courses on Canvas and other LTI (Learning Tools Interoperability) services. For full instructions on setup, see the documentation.

Once a course is linked, instructors can go to [Course] > Manage Course > Manage Course Users to refresh the roster:

Instructors can also edit "Linked Course Settings" to configure whether or not to auto-drop students who are not enrolled in a linked course.

Streaming Output

#1622, #1645, #1671, #1679, Tango #223, Tango #225

Updated feedback interface

The feedback interface now features a two-column panel for displaying feedback. The left-hand side features the autograding output as well as a status (Queued, In-Progress, or Completed) badge, and the right-hand side features a results panel, with the student's scores for a submission.

Partial Output

Submissions being graded are now clickable with a clock icon rather than a plaintext dash. Once clicked, partial output from Tango can now be viewed on the feedback page as a submission is being graded. Partial feedback will be updated when the user clicks on the refresh icon.

Assignments that have been added to the autograding queue, but haven't started grading yet will be displayed as such:

Generalized Feedback

#1617, #1629 Instructors and CA's are able to leave "general" feedback on each problem, not tied to any specific line number or file. These can be accessed by pressing the plus button next to a problem header.

Once added, the general feedback comments will be displayed with a badge indicating the number of points. When hovered over, they can be edited or deleted.

Breaking Changes

• #1470 Rails upgrade to 6

• Upgrade of old gems
• Table migrations needed due to schema changes for new features

New Features

Metrics included/excluded categories

Speedgrader Features

Adjustable speedgrader layout

#1486 Using the Golden Layout library, we have introduced a new interface for the speedgrader. Components of the layout are now draggable, expandable, closable, and resizable. Layout changes will persist in all speedgrader pages, but users may also reset the layout back to the default configuration using a "Reset Layout" button.

Autofill comments

#1497 Course Assistants and instructors are now able to optionally add their code annotation comments to the "comment pool." This shared comment pool will appear as "autofill" options in the comment textarea to all graders for an assignment. When a comment is selected from the dropdown, the comment will populate the textarea for the grader to post.

Version dropdown menu and buttons on view submissions page

#1508 #1503 #1574 We introduce an easier way of switching between the different versions of a student's submission. Either 1) Use the dropdown to select a specific version, or 2) use the [ and ] buttons to switch between the next and previous versions that contain the same file.

Improvements

Shared group improvements

• #1478 #1484 add API endpoints for getting, creating, and deleting groups so that instructors can create groups dynamically. See updated docs here.

New Features

GitHub Submission

We now introduce GitHub submission for assessments. Instructors can optionally enable GitHub submission for assessments as they see fit. Students can connect their GitHub account with Autolab and submit from a particular repo's particular branch of theirs directly. See instructions here for how to set up. Once you have set it up for your Autolab instance, you can enable GitHub submission by checking the GitHub submissions checkbox in the assessment settings. Students can then connect with their GitHub account and submit by selecting a repo's particular branch.

Improvements

• #1436 #1414 #1402 Roster upload workflow improvement: The previous roster upload workflow can be confusing and ineffective and we as devs are already forgetting what these were like! Here's a more smooth and human-readable and -navigable roster upload process: select your file, press upload, error banner shows up if there are any errors/table of potential upload is shown, press confirm if there are no errors. Allow us to highlight 1) the specific error message in the error banner and 2) sortable entries of the table of potential upload.

New Features

Autolab Docker Compose

We have finally introduced the new way to install Autolab, using Docker Compose. This is now the preferred way of installing Autolab as it makes installing and maintaining a production ready (i.e. ready for classes!) Autolab. Find the installation instructions here

Student Metrics Feature

Traditional approaches of identifying students who are struggling with class is reactive; course staff wait for students to come to them to provide help, which can often be too late. We are introducing the new student metrics feature that tracks metrics that signify potential risk, which would help us identify students in need of attention early in the course. Read more about it here

Autolab Documentation

After multiple rounds of review, we have the new and improved Autolab Documentation (which is now also part of the main Autolab repo). It should be easier to navigate and use. Of course we finally made it the iconic Autolab red. Located at the same address as before, https://docs.autolabproject.com/.

Speedgrader - The new code viewer

• The File Tree shows file hierarchy of student’s submission
  • Click on a file to open
  • Click on a folder to expand
• The Symbol Tree allows you to jump quickly to functions in the student’s code
  • Click on a function to jump
• You can easily switch between submissions and files
  • Up/down arrow keys change file
  • Right/left arrow keys change submission
• How to use new annotation system:
  • Make annotations with grade adjustments
  • Important: annotations can only be made for non-autograded problems (to preserve the original autograded score of the autograded problem)
  • Annotations grade changes summarized by the Annotations table on the right
• New: Score for problem automatically updates after annotation score changes based on the following formula (this no longer has to be done manually on the Gradebook):

score = max_score + ∑(annotation score changes)

• For example, a way to grade style in a deductive manner would be to set the max score for the Style problem, and make annotations with negative score for style violations and zero score for good style

UI Enhancements

• Tables are more standardized
• Fixed text overflowing issues on Gradebook modals
• Improved standardization and UI for annotations on PDF submissions

Others
