LTI 1.3 is based upon LTI 1.1 but uses the IMS Security Framework, which is based on the industry-standard protocol IETF OAuth 2.0 for authentication services along with JSON Web Tokens (JWT) for secure message signing and the Open ID Connect workflow paradigm.
The initial release of LTI 1.3 in LTI Pro does not provide any additional functionality for Instructors or Students that use the LTI. The user interface for LTI 1.3 is the same as the user interface for LTI 1.1.
LTI Advantage is a set of three LTI services based on the core LTI 1.3 specification: * Assignment and Grade Services seamlessly syncs grades, progress, and comments from multiple sources into an LMS platform’s grade book, greatly reducing faculty effort and the chance of errors. * Deep Linking supports a natural and efficient user workflow between a learning object repository or content tool and the LMS platform when developing courses and programs, again saving teachers’ time. * Names and Role Provisioning Services securely share course roster/enrollment information with the requesting tool to enhance users’ experiences and provide administrators a basis for who has used the tool and importantly, who has not.

Zoom’s LTI Pro will support LTI 1.1 indefinitely. Going forward there may be LTI Pro enhancements that will require LTI 1.3.
