This is a small point release to fix a bug that apparently was introduced pre-v1.0.0, but due to differences in how registries handled the location of manifest references the issue did not present itself until recently with a team utilizing Artifactory to store multi-platform images.
Thanks to @hmtai and @ashank07 for finding and documenting this issue in #98. The bug was fixed by PR #100
Pre-packaged Docker images have been updated to this release on DockerHub: mplatform/manifest-tool:v1.0.3
