The record

Purpose: Knative provides Kubernetes middleware for building, deploying, and managing serverless workloads.
Serving: Knative Serving manages stateless HTTP services, including deployment, routing, and automatic scaling.
Autoscaling: Serving can scale services from zero in response to incoming traffic and scale them back down when idle.
Traffic management: Serving supports blue-green deployments, canary releases, and traffic splitting between revisions.
Eventing: Knative Eventing provides asynchronous event routing using CloudEvents over HTTP.
Functions: Knative Functions provides a framework for building and deploying stateless functions as containers.
Integrations: Installation documentation lists networking integrations including Istio, Contour, and Gateway API, and messaging integrations including Kafka, RabbitMQ, and NATS.
Supported install platforms: The installation guide lists Linux, macOS, and Windows as supported platforms.
Deployment options: The installation guide describes local quickstart and production installation on an existing Kubernetes cluster using YAML or the Knative Operator.
Portability: Knative runs on Kubernetes clusters across cloud providers and on-premises environments.
Security model: Knative relies on Kubernetes security capabilities, including RBAC and namespace isolation, and its threat model recommends securing the chosen routing and event transport components.
Security artifacts: The threat model says Knative signs project container images and CLI binaries and supplies an SBOM and SLSA provenance statement.
Security reporting: The project asks vulnerability reporters to contact its private security email list, and says reports are investigated by community volunteers.
Feature maturity: The feature documentation says alpha features may contain bugs, change incompatibly, or be dropped without notice, and recommends them only for short-lived testing clusters.
