This release is beginning the settling of dust for the v1 release. That is not to say there may not be breaking changes between now and the final v1, but they will be reviewed for strictest necessity and adhering to compatibility with the Docker format that this spec was drawn from.
Changes with v0.4.0:
Additions: * Go package added for types https://godoc.org/github.com/opencontainers/image-spec/specs-go/v1 (#172) * oci-image-tool: man page docs added https://github.com/opencontainers/image-spec/tree/master/cmd/oci-image-tool/man (#180) Minor fixes and documentation: * oci-image-tool: replace colon with hyphen to be windows friendly (#177) * oci-image-tool: fix various bugs in extraction of images (#177) * manifest: size as int64 allowing for huge containers (#153) * manifest: move duplicate descriptions to reference descriptor doc (#167) * serialization: explain opaques and their role (#171)
This is a "getting started" release and makes no guarantees the v0.2.0 will be backwards compatible. Overall, we have imported the relevant docs, added information about the media types, and created the new media types for the OCI. It isn't perfect but it is enough to start having discussions with people implementing registries and build systems.
