Canvas Deploy Notes (2021-02-03)

Canvas deploys contain code changes that are intended to fix bugs, improve performance, and prepare for new features, but they do not affect customer workflows. These deploys take place every two weeks and can be tested in the beta environment before the production deploy date indicated in the title of this document. Intended changes in workflow are noted in the Canvas Release Notes published monthly.

Deploy notes may include notable fixed bugs, resolved fixes in Known Issues, and other updates that do not affect user functionality.

Deploy Notes Change Log


Fixed Bugs




The All Courses heading has been changed from H2 to H1.

User Profile

The hidden User Profile heading is identified as an H1 for screen readers.


Assignment Enhancements and Closed Captioning

Caption files can be added to media submissions in the Assignment Enhancements feature.

Explanation: When the Assignment Enhancements feature was enabled, and a caption file was added to a media submission, Canvas generated an error and the upload failed. Canvas code has been updated to add translation support for Assignment Enhancements.

Assignment Enhancements and Observer Roles

Observers can view assignments when the Assignment Enhancements feature is enabled.

Explanation: When the Assignment Enhancements feature was enabled, observers were unable to view assignments. Canvas code has been updated to allow observer roles to view course assignments.

Blueprint Courses

Blueprint Course Icon and Student View

The Blueprint Course icon does not block the Student View icon.

Explanation: When a course is a Blueprint Course or an associated course, the Blueprint Course icon blocked the Student View icon. Canvas code has been updated to adjust the placement of the Student View button when the Blueprint Course icon is visible.

Course Import

Date Shifting

When an assignment has a due date, and a course does not have start or end dates, shifting dates in the course imports page does not prevent the course from being created.

Explanation: When an assignment was imported with due dates, but the course dates were blank, the import would fail and identify the assignment due date to be before the course start date. Canvas code has been updated to improve the course import process for courses with no start and end dates.

Learning Mastery Gradebook

Outcomes and Post Policy

When an assignment is associated with an outcome, learning mastery outcome results are displayed based on the assignment post policy.

Explanation: When an assignment was set to display grades as any option other than Not Graded, and the assignment is associated with an outcome, students cannot view mastery in their Grades page until the assignment submission includes a score or grading comment in addition to the Outcomes evaluation. Canvas code has been updated to not make learning mastery results dependent on a comment or a submission score. Instead, viewing mastery results is based on the post policy set for the assignment.


File Uploads and Course Export

Media files can be viewed when exported as an HTML file for offline viewing.

Explanation: When course content was exported as an HTML file for offline viewing, media files that were first uploaded to the course or user files and then embedded in a page or added to a module could not be viewed. Canvas code has been updated to fix exports when media objects are in course files.

Rich Content Editor

Editor Window Size

All pages in Canvas are full width when the window is larger than 1450 px.

Explanation: When the New User Tutorial feature option is disabled for a course, the Rich Content Editor does not expand to the full width of the window after the window is larger than 1450 px. Canvas code has been updated to make all pages in Canvas full width when larger than 1450 px.

LTI Icon Size

All LTI icons are 16px in the Rich Content Editor.

Explanation: When the LTI menu was expanded in the Rich Content Editor toolbar, the icons displayed larger than the icons directly in the toolbar. Canvas code has been updated to size the height for all icons in the Rich Content Editor at 16px.

Hi Canvas! Long time user, first time poster.

RE your update to Editor Window Size: Making the Canvas page width the full width of the screen results in a very poor readability experience for users with large monitors, especially for text heavy pages (great article on UX perspective of this).

I would be curious to hear the rationale for this particular change, as it doesn't appear to have any clear benefits for end users.

Hi @rory_green 

Our team is working on this right now and will get it out to the production environment as soon as they can.



The 1/20 deploy notes comments direct us to follow these 2/3 notes for updates on the Copy To/Share To change that started populating closed/uneditable courses in the course selection list. Any updates? I've given my teachers workaround instructions but they're frustrated that this hasn't been fixed.

I'm here to echo @audra_agnelly 's question about the proposed fix to the Copy To/Share To problem introduced in the 1/20 deploy. Looking forward to an update.

I would also like to know what's going on with the Copy/Share to problem introduced in the last deploy.  I posted on the 1/20 deploy notes earlier (but didn't receive a reply yet), have a support ticket filed, and raised the issue with our CSM as well.  I don't understand why sharing/copying TO a concluded course (whether concluded manually or by term dates) would be allowed.  Pretty much everything on a concluded course is locked down, so this change doesn't make sense.  Sharing FROM a concluded course to something active should work though.  Looking forward to any updates.


@rory_green I came here wondering the same thing regarding the page width, as it introduced a few issues on our end, but it seems that the width change has been reverted back to normal. Thank you, @erinhmcmillan and team!

@nicholas-cheval @chriscas @shaneros @audra_agnelly changes don't always come out in the following deploy. When it's available it will be announced.

The width of the Rich Content Editor has been deployed to the production environment and is resolved.
