0.6.1 - 2024-03-28

Fix a bug where the plugin would try to publish OCI images without a repository.
Will now default to "latest" as a tag if none is specified.

Adding layers to an image is changing. As a preparatory step, there's now an oci_layer target. Add these to the layers field of an oci_image_build, instead of dependencies. These will process a bit better, and gives more control over what goes into each layer.
Mac support has improved. In order to provide determinism, the gtar (GNU tar) binary has to be available.
Both umoci and skopeo are now supported on Mac M1 and x86_64. This plugin does not support image run steps on Mac still.
When pulling multi-arch images you can now specify os and architecture on the oci_pull_image target
Fix a bug where OCI layer building would fail if no dependencies were specified

Improved support for very large layers > 2GB. A lot of layers will now be compressed in transit. This adds some overhead later when injecting them into image, but fixes some crashes inside Pants.
Improved support for multi-stage builds (COPY --from)

There is now support for building artifacts in one container and copying them into a new container. To do this, use oci_build_layer, and configure the output files and directories. The files and data will be inserted verbatim into the downstream container.
Adds support for empty base images (FROM scratch)

This change enables you to use base=["//:empty"] to start from a completely empty container. This can be useful to produce containers with statically linked binaries that require no runtime environment at all.
- To change the target name, set [oci].empty_image_target in pants.toml.
