The default value of this flag is false. This improves the user experience by properly setting expectations.
  • Added a new video recording Question type. This allows users to record and submit video responses to Questions within supported browsers.
  • SET consumer/keys/lti: You can now set your own LTI key & secret pair instead of using the keypair generated by Learnosity. A valid key and secret must be 16-255 characters long, and is limited to characters allowed in HTTP headers.
  • SET sessions/template: Added support for gridded, choicematrix and longtextV2 Question types. Those can now be included and scored in paper-based assessments and other off-line tests.
bugfixes
Items API v1.84.1, Assess API v2.80.0, Questions API v2.124.0, Author API v1.35.0, Question Editor API v3.50.0, Data API v1.25.0,
  • Enforced case-sensitivity for Item references in adaptive Activities, in line with the normal behaviour of Items API.

  • Fixed a bug where the flag button and calculator button weren’t showing tooltips when the user’s cursor was hovering over the button.
  • Fixed a bug so that only the vertical_stretch_option will be applied when both vertical_stretch_option and scrollable_option are both enabled at the same time in the Items region. This will prevent conflict between the two settings.
  • Fixed an issue with internationalization labels not applying to Image Highlight Question types.
  • Fixed an issue where opening the Calculator feature could cause the page position to jump to the top of the page.
  • Added unique ID to sharedPassages taking into account occurrences of the same passage across multiple sections. This fix makes passages unique to their section.
  • Fixed a bug that causes custom Question type from calling the validate event before the ready event is triggered in review mode.
  • Fixed an issue with Basic Extended calculator where the % function was inconsistent with the existing Scientific Calculator.
  • Mathcore v1.59.0
    • Added support for primes as a variable character.
    • Added use of rules in "trig" identities.
  • Fixed a bug where Item references were being duplicated on the Item list.
  • Fixed slow performance on the Item list for some queries.
  • Fixed a bug where loading Question Editor would make other instances of CKEditor hidden.
  • GET itembank/items: Fixed slow performance for some queries.
polish
Author API v1.35.0, Data API v1.25.0,
  • Updated message to show option for duplicating passages only if the Item being duplicated has a passage and duplicate_shared_passages option is set to true.
  • SET sessions/template: Tightened validation of the session_id attribute. Various elements of the system assume it to be a UUID, which led to downstream processing error when it was not. The endpoint now rejects the payload upfront with an indication that the attribute needs to be fixed before continuing.
features
Items API v1.84.0, Assess API v2.79.0, Questions API v2.123.0, Author API v1.34.0, Data API v1.24.0,
  • Dynamic data now supports the characters " and \. This means authors don't need to manually enter unnecessary backslash \ characters when authoring.
  • Added mapping for Events API to support LTS versioning.
  • Added support for caching inline public methods for Items API.
  • Changed the behaviour of the submit dialog which was showing the close button when the "limit_type": "hard" init option was enabled. It previously allowed users to go back to the assessment.
  • Added an invisible character for texthelp support in matchlist. this will help screen-reading software process the words on the page.
  • Added an option of splitting the js property in custom Questions to Question and scorer within one object.
  • Added a Feature exposing an itemlist:selection:changed public event (when in item_list mode and enable_selection is true), whenever the user selects/unselects an Item and also when a selection is cleared using the clearSelectedItems public method. This allows you to identify selected Items to act on with a "save" button. It also works with pagination.
  • Allow specifying search filters in the Item lookup tables for Activity edit.
  • Fixed bugs and improved the user experience for authors who use audio recording when creating the Audio Player simple Feature.
  • For the math keypad, LaTeX can now be added into dynamic data without any need for extra escaping. LaTeX used anywhere else still requires the \( \) delineators. This allows authors to more easily input LaTeX since they don't need to add in extra escape characters.
  • If the following conditions are met: then the URL will now automatically be converted into a HTML img element. This enables authors that are unfamiliar with HTML to embed images simply by pasting the URL.
  • GET sessions/responses: custom session metadata can now be retrieved in the response using the "include": ["sessions.session_metadata"] option, so the session metadata is conveniently available while processing the responses and score data.

    • Infinite repeating decimals
    • Decimals with a trailing zero
    • Measure of angle
    • Singular ordinal fractions
    • Mixed numbers
    • Unary plus
  • Fixed a bug where an error fetching past events on subscriber initialisation would prevent receiving any future events.The API still reports the error in the console, records it in the LearnosityEvents.errors list and sends it to the errorListener if specified, but now continues to send subscribe requests to retrieve new events and deliver them to the application.
  • Fixed the messages reported on backend errors. Previously, raw backend error responses were reported verbatim in the console. An additional error message is now reported, if available, giving more context about what the error means for the API (e.g., fatal or not). This does not impact what gets recorded (i.e, the error only) in LearnosityEvents.errors nor sent to the errorListener.
  • Fixed a bug where requests denied with 4xx HTTP errors would be retried in a tight loop. This prevents overloading the backend with a lot of known-incorrect requests. As before, the request is passed to the caller's errorListener, allowing it to be informed about the issue and take further corrective action if needed.
  • Fixed an XSS vulnerability where inserting an HTML tag with any "on" event function causes said function to be executed.
  • SET /itembank/items/tags - fixed a bug where supplying the same Tag with different spacing within its type or name can trigger a 500 server error. It now treats the above scenario as two separate Tags.
  • GET /itembank/questions - fixed an issue where a non-string array of references or item_references would trigger a 500 server error. The request now returns a validation error instead.
  • GET /itembank/items - fixed an issue where a non-string array of references or questions.references would trigger a 500 server error. The request now returns a validation error instead.

  • Fixed an XSS vulnerability where inserting an image with an "on error" function and an invalid image source value causes the error function to be executed.
  • Fixed a bug that was causing empty paragraphs above and below certain top level block elements when authoring content with a rich text editor.
  • Fixed bug in session/responses endpoint where a combination of several user and activity ids could lead to a timeout of the endpoint. The endpoint is now able to fetch data for those combinations in linear time.
