Arcjet has released v1.0 of its JavaScript SDK after two years of development, marking the transition from beta to a stable, production-ready API. The release emphasizes stability and minimal breaking changes as core features, with only three breaking changes introduced during the entire alpha/beta period. The team prioritizes predictable monthly releases, backwards compatibility, and reducing dependency churn to prevent developer fatigue. This milestone represents a commitment to long-term API stability, allowing teams to integrate security tooling without ongoing migration overhead.
