Usage

# syntax=docker.io/docker/dockerfile-upstream:1.23.0

Notable changes

• Git URLs now accept the mtime=commit query parameter to initialize checked-out file timestamps to Git commit time. Remote builds using a Git context that define SOURCE_DATE_EPOCH automatically default to mtime=commit for better reproducibility. #6600
• Dockerfile can now define SOURCE_DATE_EPOCH build-arg in the global scope with a default value. The value can still be overridden with --build-arg as before. #6601
• Fix issue with the order of applied proxy build-args being non-deterministic #6560
