Iaito is not in active development, the current focus of the project is in simplicity, reduce tech debt by removing superfluous, anoying or mainly unused dependencies like python support or plugins, breakpad, the cmake build system, crash reports or auto-updates features, as long as the project is under low maintainance mode is good to remove stuff that distract the attention from the core which is the one that should be handling all that stuff. Iaito focus on exposing the capabilities of r2 instead of duplicating efforts in a GUI.
