Hi Gilles, back in October I reported an issue with OpenCV that was tracked to an upstream dependency in vcpkg.</div>

Has the change you referenced below been made in 8.9.0, and if so, is 8.9.0 stable enough for testing on a production photo library? Please let me know if there is a bug I could track instead; I did check but did not find one.</div>
