Latest

Our rolling release. This release contains in-development new features released since the most recent Long Term Support.

This should only be used for in-development systems targeting a production release using the next Long Term Support release (see our Learnosity Help article for further details) or for testing upcoming features while in-development.

21st Apr 2021

Features

Assess API v2.116.0, Questions API v2.170.0

Added a new background to indicate a partially attempted status for the Item icon in the review screen panel.
Added a filter to sanitize content pasted into the response field of essay Question types. Images and math content pasted from external sources will no longer be accepted, as this was causing issues with submitted responses. Images should be added using the image tool, and math should be entered using the Learnosity math editor. This will result in cleaner and more reliable data in the system.
Added spellcheck support for the text tool in the drawing Question type.
Added spellcheck support for the imageupload Question type.

Fixed a bug that prevented audio from playing, when using the audio player public method.
Fixed a bug, handling pasting and dragging and dropping of external images and MathJax in longtextV2, chemistryessayV2, and formulaessayV2 Question types, so that invalid data doesn't get persisted in responses.

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.
