Release Spotlight: etcd v3.6.0
Yesterday, etcd (a CNCF Graduated project) announced its first feature release in 4 years(!). The database migrated to v3store, a new storage engine with better performance and transactional support. Etcd now also fully supports downgrade (to migrate the data schema to a required etcd version), Kubernetes-style feature gates (to manage new features), new discovery protocol (
v3discovery), and /livez and /readyz endpoints similar to Kubernetes liveness and readiness probes.New etcd version reduces the average memory consumption by at least 50% and improves both read and write throughput by approximately 10%.
Other noticeable updates in the Cloud Native space:
1. Kyverno, a Cloud Native policy engine (a CNCF Incubating project), released its 1.14, bringing two new specialised policy types (ValidatingPolicy and ImageValidatingPolicy), streamlined validation with improved CEL support and performance, enhanced supply chain security with dedicated image verification, and CEL expressions support in policy exceptions.
2. Helmfile, a declarative spec for deploying Helm charts, reached its v1.0.0. This update introduced the ability to sync release labels to the target release across various commands and configurations, added the
--take-ownership flag to helm diff, and removed several outdated features, such as its double rendering workaround and loading charts.yaml.3. Calico, a Cloud Native networking and network security solution from Tigera, was updated to v3.30.0 with many new features. They include tech previews for Calico Whisker (a web console for network activity observability), flow logs API, and Calico Ingress Gateway (an enterprise-hardened distribution of Envoy Gateway). It also introduced staged network policies to test policies before applying them, Quality of Service controls, service LoadBalancer IP allocation support in IPAM, custom host endpoints for nodes, OpenStack Caracal support, and even more.
