March 2026 monthly summary focusing on key accomplishments across two repositories: confidential-containers/cloud-api-adaptor and openshift/sandboxed-containers-operator. The month delivered reliability improvements for VM lifecycle, security patches, and architecture-aware runtime adjustments, driving reduced operational risk and stronger security posture.

In 2025-10, delivered IBM SE support for the kata-cc Confidential Computing Runtime Class Handler in the sandboxed-containers-operator. Introduced the kata-cc-ibm runtime class and refactored the detection of multiple TEEs to use a counter-based mechanism, enabling IBM SE alongside existing Intel TDX and AMD SNP while enforcing a single TEE platform per cluster to prevent conflicts and maintain stability. Commit: a7161c47111b0bc2abd3352ccd1a381ad10d1bf4 (controllers: create kata-cc-ibm runtime class). This work enhances security staging, reduces misconfig risks, and improves runtime reliability for confidential computing workloads.

Monthly summary for 2025-08 focusing on end-to-end testing improvements for Libvirt Pod Init Containers in confidential-containers/cloud-api-adaptor. Delivered end-to-end test coverage to validate pod init-container handling, integrated new test helper, and reinforced CI signals. No critical bugs fixed this month; the emphasis was on building reliable test infrastructure and increasing confidence in libvirt/pod lifecycle workflows.

July 2025 monthly summary for confidential-containers/cloud-api-adaptor: Implemented a critical Umoci dependency upgrade to 0.5.0 to access latest features and security patches, while preserving API stability.

May 2025 monthly summary for openshift/sandboxed-containers-operator. Focused on stabilizing builds on s390x by pinning umoci to a specific version to avoid upstream breakages, delivering a deterministic and reliable build process. The fix reduced build instability and downtime, improving CI reliability and deployment confidence for the operator in production environments.
