In October 2025, the stackrox/stackrox team delivered a focused set of features and reliability improvements across build tooling, TLS reliability, database CI, deployment readiness, and documentation. Key changes include reverting arm64 support in the build pipeline and updating operator-sdk/helm dependencies to maintain stable amd64 builds; implementing TLS leaf certificate caching to optimize TrustInfo dispatch; upgrading PostgreSQL to v15 in docs and CI while removing older PostgreSQL 13 tests to streamline the matrix; enhancing Kubernetes deployment readiness checks and TLS challenge reliability in tests; and comprehensive documentation improvements (AGENTS.md, TLSChallenge endpoint docs, and changelog corrections). These efforts reduce build risk, speed up CI feedback, improve TLS reliability for production workflows, and improve developer onboarding and traceability.

September 2025 monthly summary for stackrox/stackrox highlighting the delivery of a robust Certificate Authority (CA) rotation framework across Helm-based Sensors and Operator-managed components, with automated rollouts and strong test verifications. Delivered end-to-end CA rotation, including fingerprint-based signing, per-installation enablement flags, automatic redeploys on CA changes, and CA promotion. Implemented a dedicated feature flag by install method, and enabled CA rotation in Operator-managed Central and Sensor. Replaced hard-coded TLS secret labels with configurable approaches, improved CA rotation selection logic and resilience across upgrades, and added end-to-end/KUTTL tests to validate rotation paths. The work reduces operational toil, strengthens security posture, and accelerates safe CA lifecycle management in production.
