Thus release fixes 45 bugs reported since 1.1 was released. It also adds support for interacting with metamodel-less models (muddles [1, 2]) and includes several minor enhancements to the development tools and underlying engines of existing Epsilon languages (e.g. improved caching of EMF models, cached models view, integration with Luna's dark theme)
