Dear ILIAS-Administrators,

we would like to inform you about recent improvements in the LTI Consumer Component of ILIAS for release_11. In the last years there have been various uncertainties about the implemented and working feature set of LTI. Thus, we decided to improve this situation within the release_11 branch: Some features that pretended to work in older ILIAS versions such as deep linking or the assignment and grade services did not work as expected although the corresponding feature wiki articles and GUI elements pretend that they do.

Our current authorities for LTI proposed us to clean things up for the LTI Consumer side for ILIAS 11 which generated a lot of code changes for this component within a stable release: To make sure that everything works correctly we founded a working group that thoroughly tested all improved parts of the implementation. The results of this testing convinced us to take the next step and introduce these changes which can be interpreted as a border case between bugfix and feature into the next shipped ILIAS 11 release which will be ILIAS 11.4. This is an exception in the ILIAS development process in order to address a very important quality enhancement within the LTI component. The Technical Board did not take this decision lightly but we hope for your understanding on this unique situation.

That means from ILIAS 11.4 on the LTI Consumer side (which means that you open learning content from an external service within your ILIAS installation) will fully support the LTI 1.3 specification including deep linking, dynamic registration and the assignment and grade services. The corresponding Feature Wiki articles will be updated by the Technical Board, the corresponding Authorities and the Product Manager in order to make this change traceable. We are happy to announce this significant improvement and want to thank surlabs for all the effort that they invested in shipping an even better ILIAS.

In case you are a heavy LTI user and want to help out in testing LTI in upcoming ILIAS releases we and the testcase manager are happy if you reach out to us via tb@ilias.de and offer your help in future testing. This is especially important now since the corresponding changes (and additional ones) on the Provider/Tool side of the LTI implementation are planned to be released in the upcoming ILIAS 12 release and need to also be thoroughly tested during the testing phase which will start on NOV 4th 2026.

Let us keep ILIAS being a great software.

Best regards, Rob

For the Technical Board of the ILIAS Society
