As discussed here:

#4447

• kpt does not have an API on wire, but it has an API on types
• kpt has some API objects in the repo first
• Let's do semantic versioning for kpt, the SDK and for the individual functions in the function catalog

Things what we need to do before announcing v1.0.0

• There are some types copied from Kuberntes and kubctl. We should go back and use the upstream ones. These are in kpt and in Porch also
• Update the documentation
• The SDK and the function catalog have their separate versions
• kpt version should also provide the right version on all architectures

Dependencies

• The functions use the SDK and the SDK uses kpt
• The function use only kpt types, there is no need to bump the version in the functions until the types are backward compatible
