April 2026: Implemented a security-focused Istio upgrade for kyma-project/istio and hardening measures to reduce risk. Key changes include upgrading Istio to 1.29.1 with breaking-change mitigation and environment adjustments, enabling seccompProfile for Istio sidecars to limit system calls, and updating release notes and documentation to reflect new features and actions (including HTTP compression support and Kubernetes Cluster Roles). Unit tests were updated to align with the changes. No explicit user-reported bugs were fixed this period; the work reduces risk and strengthens the upgrade path for future iterations.
