We're rapidly iterating on enhancements for accelerating builds both locally and in CI. For example, we now have a significantly faster --load that makes it possible to load your image back into your local Docker daemon in seconds.

We've added a few more enhancements to make things even faster. We made exporting layers for both --load and --push significantly quicker. We effectively made the export run in parallel rather than serially. The net effect is 2x faster builds on average.

We also updated build and bake in how they search for a depot.json file. Previously, it would search for a depot.json file in the root directory. Now, it will check the filepath specified for a given file first and then recursively search up from there. You can still pass in the project ID for either command via --project instead of using a depot.json file.
