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 for further details) or for testing upcoming features while in-development.

13th Mar 2019
Features
Data API v1.28.0,
  • Added two new attributes, max_score_of_attempted and max_score_of_unmarked, to the output of the GET /sessions/scores endpoint for each session returned. These new attributes provide a more complete picture of the state of a session's score, including whether manual scoring may be required.

2019.1.LTS Recommended

This provides a stable, supported codebase, receiving stability & performance code fixes for its full lifecycle.

This is our recommended version for production releases right now.

  • Released: 27th February 2019
  • End of Life: 28th February 2021

20th Feb 2019
Bugfixes
Data API v1.27.1,
  • Fixed input validation for the SET itembank/items endpoint to force the Item definition to match the Item's Question and Feature references. This reduces scenarios where the Item can be mistakenly saved with the wrong set of widgets.
  • Fixed a bug in the SET itembank/activities endpoint where an Activity with resource_items could not be saved.

9th Jan 2019
Features
Data API v1.27.0,
  • Added support for specifying the creating user when calling the SET /itembank/activities/duplicate endpoint, by providing the meta.user parameter. The specified user will be marked as the creator of the newly duplicated Activities/Items/Questions/Features (for the purposes of audit trail and when retrieving the entities via Data API).

  • End of Life: 30th September 2020

10th Dec 2018
Bugfixes
Data API v1.26.5,
  • Internal performance improvements for executing requests with Learnosity servers.

14th Nov 2018
Bugfixes
Data API v1.26.4,
  • Fixed an error in SET itembank/items/duplicate that prevented an Item from being duplicated if it contained Tags with different numeric names representing the same integer value, for example "001" and "01".

3rd Oct 2018
Bugfixes
Data API v1.26.3,
  • Fixed a bug in SET /itembank/items/duplicate where all-numeric reference strings were rejected as invalid even though they were passed in correctly.

27th Sep 2018
Bugfixes
Data API v1.26.2,
  • Fixed bug in SET /itembank/items/tags where a large item/tag combination could make the request fail. Requests are now split and batched internally to allow appropriate scaling.

12th Sep 2018
Bugfixes
Data API v1.26.1,
  • 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.

27th Aug 2018
Bugfixes
Data API v1.26.0, v1.25.2,
  • 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.
Polish
Data API v1.26.0, v1.25.2,
  • Added a Request UUID to all Data API Endpoints which identifies the request in the Learnosity system. The UUID is returned in the response metadata on error. This UUID can be communicated to Learnosity support to assist with investigating root causes of unexpected errors.

1st Aug 2018
Features
Data API v1.25.1,
  • Improvements to internal tracking mechanism.

11th Jul 2018
Features
Data API v1.25.0,
  • 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
Data API v1.25.0,
Polish
Data API v1.25.0,
  • 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.

20th Jun 2018
Features
Data API v1.24.0,

Our first Long Term Support release. This provides a stable, supported codebase, receiving stability & performance code fixes for its full lifecycle.
