0.66.0

News

Tons of small feature additions, and 3 new contributors in this milestone.
Highlighted first is the 3 most discussed changes:

Support for auto-generating schemas for enums in kube-derive

It is now possible to embed complex enums inside structs that use #[derive(CustomResource)].

This has been a highly requested feature since the inception of auto-generated schemas. It does not work for all cases, and has certain ergonomics caveats, but represents a huge step forwards.

Note that if you depend on kube-derive directly rather than via kube then you must now add the schema feature to kube-core

New StreamBackoff mechanism in kube-runtime

To avoid spamming the apiserver when on certain watch errors cases, it's now possible to stream wrap the watcher to set backoffs. The new default_backoff follows existing client-go conventions of being kind to the apiserver.

Initially, this is default-enabled in Controller watches (configurable via Controller::trigger_backoff) and avoids spam errors when crds are not installed.

New version priority parser in kube-core

To aid users picking the most appropriate version of a kind from api discovery or through a CRD, two new sort orders have been exposed on the new kube_core::Version

• Version::priority implementing kubernetes version priority
• Version::generation implementing a more traditional; generational sort (highest version)
