November 2025 — justifi-tech/web-component-library: Delivered the Modular Checkout Hooks feature (PreSubmit/PreComplete) with CheckoutState, enabling state inspection, custom validation, and user confirmation before or during checkout. Implemented state snapshots (getCheckoutState), hook outcomes with resolve/reject semantics, and restructured the checkout flow to ensure payment data is available for hooks. Added extensive tests and documentation; renamed preSubmitHook to preCompleteHook for clarity, and simplified the hook implementation using try/catch. API and docs updated accordingly; exports include CheckoutState type and updated Hook typing. Changes are backed by a changeset to support release readiness.
