Dear all, We are very happy to announce the release of Copilot 3.11. Copilot is a runtime verification system implemented as a Haskell DSL that generates hard-realtime C99. Among others, Copilot is being used by the Safety Critical Avionics Systems Branch of NASA Langley Research Center for monitoring test flights of drones. You can learn more about it at [1]. Copilot 3.11 introduces a new library, copilot-interpreter, that isolates all functions related to simulation of Copilot specifications. The release also contains a number of bug fixes, provides a simplified API, deprecates outdated elements, removes unused code, and introduces support for GHC 9.2. A full list of changes merged is available at [2]. A substantial effort is being made to achieve NASA's Class D software classification, most notably in terms of development process (which you can partly witness in how issues and PRs are being handled on our github repo), test coverage (mostly with quickcheck), and proofs of correctness of the generated code (with what4). Copilot is being used by the Safety-Critical Avionics Systems Branch (D320) of NASA Langley Research Center to conduct experiments related to flight safety of aerial vehicles. We have also built Ogma [3], a tool that allows us to generate full monitoring applications (e.g., NASA's Core Flight System [4] and Robot Operating System [5] applications) from requirements in structured natural language. We invite you all to explore Copilot, to try it, and to extend it. If you like it, please help us draw attention to this work with a star on github or a mention online.
