Model artifacts are subject to constant evolution throughout the lifecycle of systems. The evolutionary pressure emerges from various technical and business factors throughout the overall software/system engineering endeavor. Pertinent examples of such factors include changing requirements, changing environment, and changing user base, all of which give rise to unique evolutionary challenges in various system artifacts from architecture to implementation, and even in informal artifacts, such as documentation. These challenges, if left unmanaged, may lead to deteriorating quality attributes, and in severe cases inconsistent artifacts or even incorrect artifacts, preventing the system from operating as intended. Therefore, proper support for efficient and effective evolution is required. The Models and Evolution workshop promotes novel theories, techniques, and tools to support evolution. To this end, the workshop brings together researchers and practitioners to discuss the latest developments on the topic.

Recognizing that artifact evolution is a key enabler of technical sustainability—a highly desired property of complex systems—this year's edition designates sustainability as its special theme. This will extend the traditional scope of the workshop by soliciting submissions and fostering discussions that contextualize the role of model evolution within the higher goal of sustainability.
