February 2026 (2026-02) monthly summary for evidence-dev/evidence: Delivered essential security hardening by patching dependencies across the codebase. Key CVEs addressed include QS 6.14.1 (CVE-2025-15284), Parcel 2.16.4 (CVE-2025-56648), and Preact (CVE-2026-22028). Additional general dependency CVEs were resolved to improve resilience and maintainability. A changeset was generated to document updates for release planning. Business value: reduced attack surface, safer deployments, and sustained delivery velocity through proactive dependency management. Technologies demonstrated: Node.js/npm/Yarn ecosystem, dependencies overrides, changeset tooling, and release hygiene.
