We also want to thank everyone who uses and helps promote Copilot
By the way, I'd like to give a shoutout to Joey Hess, who has built
arduino-copilot https://hackage.haskell.org/package/arduino-copilot and
zephyr-copilot https://hackage.haskell.org/package/zephyr-copilot. Joey
updated both projects immediately after our release so that they work with
Copilot 3.10.
I've just found out that he also gave a talk
https://www.youtube.com/watch?v=l-luyVRgWVU on his work, which I think
does an amazing job at showing how easy it is to get it running on arduinos.
Cheers,
Ivan

Dear all,
We are very happy to announce the release of Copilot 3.10. Copilot is a runtime verification system implemented as a Haskell DSL that generates hard-realtime C99. You can learn more about it at [1].
This new version of Copilot contains a small but important change in how structs are handled in C functions invoked by the monitors when property violations are detected. This change is API-breaking, so users of Copilot may need to adapt their systems accordingly. The release also contains a number of bug fixes, provides a simplified API, deprecates outdated elements, removes unused code, and relaxes version constraints for dependencies. 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] applications) from requirements in structured natural language.
We'd like to take this opportunity to welcome Will Pogge to the team with his first commit, and thank the Galois team for their contributions. We also want to thank everyone who uses and helps promote Copilot; we are seeing increased attention, and gave three talks in the last two months at JPL, USC, and VCU, with two more taking place this month.
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.
Happy Haskelling, The Copilot Team
