First came across this 2 days ago and found this extremely impressive. There's also a YouTube presentation where Sean goes over the main features of Circle's C++ memory: https://www.youtube.com/watch?v=5Q1awoAwBgQ https://www.youtube.com/watch?v=5Q1awoAwBgQ. This seems to be adding Rust borrow semantics and borrow checking to C++. The delivery vehicle seems to be a C++ compiler that the author has been working on for a number of of years. I couldn't find a ton more on the background of this. From a technical perspective this looks promising as a C++ successor language. The project will have to attract other members in the C++ community though.
