summary
Crossplane adds Composition Functions as pipelineable steps that run as an OCI image behind a Kubernetes Service, accept a gRPC run function request, and return a mutated JSON/YAML to drive provisioning. Functions are stateless, packaged with mutual TLS, a service account and optional CRDs, and have a Go SDK (Python SDK planned). Demo shows a composition that creates a VPC and internet gateway then a function that automatically adds labels and annotations; beta lands with Crossplane 1.14 around late October.
