It's based on Kubernetes 1.33 and CRI-O 1.33 and, together with Red Hat OpenShift Platform Plus , this release underscores our commitment to provide a trusted, comprehensive, and consistent application platform. On OpenShift, AI workloads, containers, and virtualization seamlessly co-exist, enabling enterprises to innovate faster across the hybrid cloud, without compromising on security. Available in self-managed or fully managed cloud service editions, OpenShift offers an application platform with a complete set of integrated tools and services for cloud-native, AI, virtual and traditional workloads alike. This article highlights the latest OpenShift 4.20 innovations and key enhancements. For a comprehensive list of updates and improvements, refer to the OpenShift 4.20 release notes. This latest release boosts the platform’s capabilities for AI workloads with the general availability of LeaderWorkerSet , Gateway API inference extension, and runtime Open Container Initiative (OCI) image volume source. It also strengthens core functionalities, introducing vital improvements like bring-your-own external identity provider, Zero Trust Workload Identity Manager, user namespace, External Secrets Operator for Red Hat OpenShift , Border Gateway Protocol (BGP) support. Furthermore, OpenShift 4.20 brings key advancements in virtualization, such as CPU load aware rebalancing and faster live migration, providing a more robust and versatile platform for diverse computing needs. OpenShift 4.20 now enables the X25519MLKEM768 hybrid key exchange mechanism with the Go 1.24 release as part of our journey to add support for post-quantum cryptography (PQC). This enhances TLS communications between core Kubernetes control plane components like the API server, kubelet, scheduler, and controller-manager, helping protect them from quantum-based attacks. Red Hat's latest releases of Trusted Artifact Signer 1.3 and Trusted Profile Analyzer 2.2 deliver a powerful combination of cryptographic signing capabilities and advanced supply chain analysis.
