+* Add `ADD --unpack=bool` to control whether archives from a URL path are unpacked. The default is to detect unpack behavior based on the source path, as it happened in previous versions. [moby/buildkit#5991](https://github.com/moby/buildkit/pull/5991)
+* Add support for `ADD --chown` when unpacking archive, similar to when copying regular files. [moby/buildkit#5987](https://github.com/moby/buildkit/pull/5987)
