The Coq team has decided that Coq will be renamed into 'The Rocq Prover'. Background information available here. The rename is currently in preparation, we hope to have a new visual identity and website by the end of 2024, and to do a first release of Rocq around that time.
There is now a Stack Exchange Q&A site dedicated to Proof Assistants! Do not hesitate to post and answer Coq questions there (use the coq tag).
