Released 2020-12-22
NOTE: If you are currently using Dispatch and creating LTI 1.3 dispatches, please note that there is a possibility that an LTI 1.3 dispatch launch that occurs while you are deploying this update in a multi-server setup will fail. If you think you will be in this situation, feel free to reach out to us for further information.
Bug Fixes
- Stop updateAssets API requests from incorrectly showing error messages when the updateAssetPolicy is set to either reject or strict
- Prevents parsing error from request logging when using /courses/upload endpoint
- When deleting courses through the API with the ApiCourseDeleteAttemptDeleteFiles setting enabled, only the first course version was getting deleted from the file system previously. Now all versions will be removed
Improvements
- Improve error messages for certain types of exception in xAPI request processing
- Remove detailed exception messages from launch page and AICC processor responses
- Modified default global.asax to include support of TLS 1.1 and 1.2 with outgoing requests (postbacks) on .NET 4.5
- The /preview API resource will now return a "Not Supported" error for CMI5 courses, rather than returning a launch url which then could fail when used
- Cleans up orphaned registration to learner mapping records internally if Engine fails to create a registration through the API (edge case)
- Allow adding HMAC512 / HMAC256 signatures to postbacks (if using the WebHookAuth plugin)
- Improvements to size of request when using UseDeltaRecordResultsPayload and course that record interactions
Dispatch Changes
Improvements
- Add JWT to LTI 1.3 dispatch launch page url to protect against tampering with parameters
