Happy to share our first-in-2026 digest of the prominent software updates in the Cloud Native ecosystem!
1. Apache CloudStack, an Open Source IaaS solution, updated its CloudStack Kubernetes Provider, a cloud controller manager to facilitate K8s deployments, to https://github.com/apache/cloudstack-kubernetes-provider/releases/tag/v1.2.0. It added support for network ACLs for LB on VPC networks, a configurable source CIDR list, and ARM64 support for Docker images.
2. Harvester, a hyperconverged infrastructure solution built on Kubernetes, released https://github.com/harvester/harvester/releases/tag/v1.7.0 with experimental automatic VM workload rebalancing, support for MIG-backed vGPU devices, multipath device recognition and management, NIC hot plugging and hot unplugging, Open Virtual Format (OVF), pausable node upgrades, transparent hugepages configuration, VM VLAN trunking, and volume snapshots in guest clusters.
3. Jaeger (a CNCF Graduated project) reached https://github.com/jaegertracing/jaeger/releases/tag/v2.14.0, which added a dark theme to the UI, removed legacy v1 components (query, collector, ingester), and added a bunch of experimental features, most of which are related to ClickHouse and the FindTraces implementation for this storage.
4. Keycloak, an identity and access management solution (a CNCF Incubating project), released https://github.com/keycloak/keycloak/releases/tag/26.5.0 (with 26.5.1, which followed shortly). It introduced several new features in preview, such as Workflows to automate administrative tasks, JWT Authorization Grants, exporting logs and metrics to OpenTelemetry collectors, and authenticating clients with Kubernetes service account tokens. Other release highlights are support for Caddy as a reverse proxy provider for client certificate authentication, organisation invitation management, and a guide on integrating Keycloak with MCP servers.
5. Envoy (a CNCF Graduated project) was updated to https://github.com/envoyproxy/envoy/releases/tag/v1.37.0, which brought many new features. Some of them include global module loading and streaming HTTP callouts to HTTP filters in dynamic modules, container-aware CPU detection, new MCP filter and router for agentic network, new stats-based access logger, production-ready Proto API Scrubber filter, cluster-level retry policies, hash policies, and request mirroring, and many more.
6. Kubebuilder, an SDK for building Kubernetes APIs using CRDs, has seen its https://github.com/kubernetes-sigs/kubebuilder/releases/tag/v4.11.0 release. The helm/v1-alpha projects are now automatically migrated to helm/v2-alpha, which got numerous improvements, including nodeSelector, affinity, and tolerations support, standard Helm labels for generated resources, and custom resources added to templates/extras. Newly generated projects also got their AGENTS.md files.
