CLion, an IDE for C and C++ development, has announced a free early preview of CLion Nova. This preview uses the ReSharper C++/Rider C++ language engine, rather than the “legacy” engine used in the previous version of CLion. CLion Nova aims to address performance and quality issues, as well as unify the user experience across all of JetBrains’ C++ tools. It offers faster highlighting speeds, a more responsive UI, and new functions such as refactorings and code hints. However, CLion Nova does not use clangd for code completion or highlighting. The preview build is available through the Toolbox App.
