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]
