is a stream-based DSL for writing and monitoring embedded C programs,
with an emphasis on correctness and hard realtime requirements. Copilot
is typically used as a high-level runtime verification framework, and
supports temporal logic (LTL, PTLTL and MTL), clocks and voting
algorithms.</span></span></div><div><span><span><br></span></span></div></div><div><div><span><span>Among
others, Copilot has been used at the Safety Critical Avionics Systems
Branch of NASA Langley Research Center for monitoring test flights of
drones. It also serves as a runtime monitoring backend for the
requirements elicitation tool FRET (</span></span><span><a href="https://github.com/NASA-SW-VnV/fret/" target="_blank"><span><span>https://github.com/NASA-SW-VnV/fret/</span></span></a></span><span><span>), via Ogma (</span></span><span><a href="https://github.com/nasa/ogma" target="_blank"><span><span>https://github.com/nasa/ogma</span></span></a></span><span><span>).</span></span></div></div><div><div><span><br></span></div></div><span></span><div><div><span><span>This release fixes 4 bugs in <span style="font-family:Noto Mono,Menlo,Monaco,Consolas,monospace;padding:0.1em 0.2em;font-size:0.8em;border-radius:3px"><span><font size="2">copilot-core</font><font face="arial,sans-serif"><font size="2"> and <span><span> <span style="font-family:Noto Mono,Menlo,Monaco,Consolas,monospace;padding:0.1em 0.2em;border-radius:3px"><span>copilot-c99.<span style="font-family:arial,sans-serif"> We have also removed 2 deprecated modules and one dependency.<span><span> The new release has been published on hackage, as well as github.</span></span></span></span></span></span></span></font></font></span></span></span></span></div></div><div><div><span><span><br></span></span></div><div><span><span>Current
emphasis is on increasing test
coverage, removing unnecessary dependencies, hiding internal
definitions, and formatting the code to meet our new coding standards.

for continued effort making Copilot available on Debian-based distros.
This will be extremely useful to a great portion of our users, who need
to use Copilot as a runtime verification system targeting C, but do not
need to become proficient in Haskell. We hope to continue this effort by
making Copilot easily available on other distributions and OSs.</span></span></div><div><span><span><br></span></span></div></div><div><div><span><span>Happy Haskelling,</span></span></div><div><span><span><br></span></span></div></div><div><div><span><span>The Copilot team</span></span></div></div></div></div></div>
