*In June 2010 LTI v1.0 was finalized.<ref>{{cite web|url=http://www.imsglobal.org/lti/index.html#lti1.1 |title=Learning Tools Interoperability® |publisher=IMS Global |date= |accessdate=2015-09-07}}</ref>

*In August 2012, LTI v1.1 added the ability for the external tool to pass grades back to the invoking system.<ref>{{cite web|url=http://www.imsglobal.org/LTI/v1p1p1/ltiIMGv1p1p1.html |title=IMS Global Learning Tools Interoperability Implementation Guide Version 1.1.1 |publisher=Imsglobal.org |date= |accessdate=2015-09-07}}</ref>

*In January 2014, LTI v2.0 was released, providing [[Representational state transfer|REST]]-based two-way communication between the external tool and the invoking platform.<ref>{{cite web|url=http://www.imsglobal.org/lti/ltiv2p0/ltiIMGv2p0.html |title=IMS Global Learning Tools Interoperability Implementation Guide Version 2.0 Final |publisher=Imsglobal.org |date= |accessdate=2015-09-07}}</ref> At the same time, a subset of v2.0 was released as v1.2, as a stepping stone between v1.1 toand v2.0.

*Due to complexity, adoption of LTI v1.2 and v2.0 was slow, and IMS GLC subsequently declared them to be "legacy" specifications, not in the recommended upgrade path from LTI v1.1, citing security concerns.

* In May 2019, the IMS Security Framework and LTI v1.3 were published, based on [[OAuth2]], [[OpenID Connect]], and [[JWT]]. LTI v1.0, v1.0, v1.1, v1.2 and v2.0 were all deprecated.<ref>{{cite web|url=https://www.imsglobal.org/lti-adoption-roadmap |title=Recommended LTI Adoption Roadmap and FAQ |publisher=Imsglobal.org |date= |accessdate=2018-06-07}}</ref>
