It makes use of C++17 features, has less third-party dependencies and slimmed-down code base. Cross reference features are strenghened, (see [wiki/FAQ]). It currently uses libclang to index C++ code but will switch to Clang C++ API. Refactoring and formatting are non-goals as they can be provided by clang-format, clang-include-fixer and other Clang based tools.
