Software evolution has largely been focused on low-level implementation artefacts through refactoring techniques rather than the architectural level. However code-centric evolution techniques have not managed to effectively solve the problems that software evolution entails. Instead a paradigm shift is emerging, where the evolution approaches put software architecture on the spotlight. This shift focuses on effectively documenting and modifying the architectural design decisions during system evolution, while synchronizing them with both the requirements and the implementation. The second workshop on the theme of Architecture-Centric Evolution attempted to explore the issues that such evolution approaches are dealing with, as well as the trends that emerge in this area. The workshop delved into this field, by presenting the latest research advances and by facilitating discussions between experts.
