January 2026: Cosmian/kms delivered a release-ready set of reliability and security improvements, along with clarifying SBOM guidance. The release 5.15.0 includes a new health check endpoint, support for updated cryptographic standards, and strengthened build/verification workflows (robust handling when hash files are missing and improved OpenSSL tarball hash verification), with related smoke-test adjustments. A documentation note clarifies SBOM vulnerability scan reports may display CVEs for non-target architectures due to lack of CPU filtering. These efforts reduce deployment risk, strengthen security posture, and improve compliance visibility, while continuing to optimize CLI tooling download UX and release readiness.
