Canvas Deploy Notes (2020-09-23)

Canvas Deploy Notes (2020-09-23)

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.

File Usage Rights


For institutions that have enabled the account setting to require copyright and license information for files, the Usage Rights section displays for images and documents.

Change Benefit

Affected User Roles

Files with usage rights are also indicated as such in the course Files page.

Menu Bar Content Button Selection


The Content buttons (Link, Image, Media, and Documents) in the New Rich Content Editor are split, where the left side opens the default options, and the right side displays the content menu.

Change Benefit

This change minimizes the number of clicks to open the default selection of Add Link, Upload Image, Upload Media, and Upload Document, respectively.

Affected User Roles

All Users

The New Rich Content Editor Content buttons are split to allow users to quickly access the default selection of uploading content. If a specific content item is needed, the menu option still allows users to access those content types.

Note: The Media Upload/Record option may be affected based on account settings, and the Course options for all content types is not available for student roles.

User Settings

Disable Keyboard Shortcuts Feature Option

This feature was deployed to the production environment on September 17.


The User Settings Feature Options section includes an option to disable keyboard shortcuts. 

Change Benefit

This change allows users who rely on screen readers or keyboard navigation to control their experience in Canvas with keyboard shortcuts.

Affected User Roles

All Users

By default, keyboard shortcuts are enabled in Canvas. In the User Settings page, users can choose to disable keyboard shortcuts in the Feature Options section. By default, this feature option is turned off. 

When enabled by a user, this feature option disables keyboard shortcuts in Canvas. Currently the feature only affects Modules and Discussions. Other areas of Canvas will be updated in future deploys.

Note: Canvas admins cannot manage user-level feature options.

Other Updates





Catalan (Català) has been added as an available language in Canvas.

Change Benefit

This change allows users to view Canvas in their native language.

Affected User Roles

All Users

Users can enable languages in their User Settings. Admins and instructors may enable a language for an entire account or course through Account or Course Settings, respectively. When a language is selected, users will view all Canvas areas in the selected language.


Fixed Bugs


Developer Keys

Test Cluster LTI Keys Checkbox

The Test Cluster Only checkbox does not display as an option for LTI Keys.

Explanation: When an LTI Key was added to an account, selecting the Test Cluster Only checkbox did not save when the page was saved. Canvas code has been updated to remove the checkbox for LTI Keys as the Test Cluster is not supported in LTI Keys.

External Apps

Google Apps LTI Icon

This change was deployed to the production environment on September 14.

The Google Apps LTI displays the Google Apps icon in Canvas.

Explanation: In older installations of the Google Apps LTI, the icon image was not able to be displayed without removing and re-installing the LTI tool because the image was linked to an asset that changed the icon URL. Canvas code has been updated to retain the icon URL for the Google Apps LTI.


Grade Details Tray Student Name

Clicking a student’s name in the Grade Details Tray opens the student’s Grade Summary page. 

Explanation: When a student’s name was clicked in the Grade Details Tray, Canvas displayed a page error. Canvas code has been updated to display the student’s Grade Summary page.

New Rich Content Editor

AVI Files

AVI files are supported in the New Rich Content Editor.

Explanation: When an AVI file was uploaded in the New Rich Content Editor, the file was not processed. Canvas code has been updated to support AVI files.

Embedded Video Previews

Media uploaded to the New Rich Content Editor can be previewed in the editor.

Explanation: When a video or audio file was uploaded in the New Rich Content Editor, the file could not be played as a preview until the page was saved. Canvas code has been updated to allow uploaded media files to be previewed in the editor before saving.

Inline Preview Documents

Inline preview works correctly with documents inserted as links.

Explanation: When a document was linked in the New Rich Content Editor, and the file was attempted to be previewed in the editor, the preview was not generated. Canvas code has been updated to correctly preview documents in the editor.


Rubric Assessment Transfers

Assessed rubrics save within SpeedGrader and are not applied to other student submissions.

Explanation: When an assessed rubric was used for grading, navigating to the next student before the rubric finished saving applies the rubric assessment to the next student. Canvas code has been updated to save the rubric for the intended student.
