Photo by Logan DeBorde. I’m delighted to announce the first public release of bisectrunk, a Rust CLI for parallel Git bisection of real-world software regressions. You give it a known-good revision, a known-bad revision, and a few shell hooks that describe how your ecosystem installs and tests a commit. It then finds the commit that changed the result by evaluating several candidates at once, each in its own isolated environment.
