Usage

# syntax=docker.io/docker/dockerfile-upstream:1.24.0-rc1

Notable changes

• Dockerfile now supports special arg definitions SOURCE_DATE_EPOCH=context and SOURCE_DATE_EPOCH=<stage> which set the value of SOURCE_DATE_EPOCH to the timestamp associated with the remote context or the stage respectively. When building from a Git commit, the context timestamp is the commit timestamp, and when building from a remote URL, the timestamp is resolved from the metadata of files in the TAR archive or from the Last-Modified header of the URL #6602
• Fix issue where in some cases LABEL value could incorrectly leak from stage linked via COPY --from #6713
• Formatting of History entries for HEALTHCHECK instructions has been fixed #6664
