| 0.3.1 | October 2026 | Gave the Fleet Intelligence agents their own page in **Tier 2 Autonomous Agents**, after the loyalty flywheel, and updated them: five agents (cost, recall and warranty, fleet health, rebalancing, and fleet quality) with their schedules, ADP inputs, model tools and what each one decides; the shared run shape with Bedrock Guardrails and a rules fallback; the eight executors, including the ADP digital-thread executor; guardrail G5 for engineering decisions; auto-approval for vehicle moves; and the path from an engineering decision to a recall. Added architecture diagrams for Tier 2 autonomous agents, agent data grounding and contact center escalation. Updated **Contact Center Integration** to the driver-confirmed handoff: the tenant’s chat and callback queues, the P0 checks before a roadside request or callback, the P0 callback, and the context the tier-2 agent receives in the chat. | 
| 0.3.0 | October 2026 | Reorganized the guide. **Building on CMS and ADP** now follows the architecture overview. **Agentic Architecture** covers the two-tier design and the Tier 1 conversational layer, and the new **Tier 2 Autonomous Agents** chapter brings together the Tier 2 platform, the four flywheel agents, the Finding and Action contracts, executors, the Actions framework, card delivery, the delivery broker and one **Deterministic Seams and Guards** section. **Personas and Tenancy**, **Knowledge and Grounding** and **Contact Center Integration** follow the agent chapters. The iOS screenshots moved into **The Companion App**, and the **Consumer Acquisition Screens** chapter, whose web screenshots showed the CMS fleet portal, was removed. **Security** now follows **Plan Your Deployment**. | 
| 0.2.1 | September 2026 | Added **The Companion App** chapter documenting the native iOS client: application architecture and tenant-driven presentation, voice session transport and authentication, the bidirectional wire protocol, the capture and playback audio formats and why they differ, the session state machine and its keep-alives, the Finding and Action surfaces, remote commands and their asynchronous acknowledgement model, the Acquire journey including the configurator step sequence and kiosk mode, client-side triage timing, and the instrumentation and logging rules for the voice path. The client previously appeared only as passing references across the agentic-architecture, customer-journey and troubleshooting chapters. | 
| 0.2.0 | September 2026 | Renamed to **Guidance for Agentic Vehicle Experience on AWS** (formerly **Connected Vehicle Experience**). Documents the two-tier agentic architecture: Tier 1 conversational agents (Nova 2 Sonic voice, text, iOS cards) paired with Tier 2 autonomous agents. Adds the AVX agent pattern chapter (Finding contract, Action contract, executor dispatch), the deployed Tier 2 platform-health agent (battery / tire / brake), cross-surface Actions with six executors and the delivery broker, iOS card feed and consent-gated APNs push, standing-claims identity model, and the stubbed roadside-assistance dispatcher. Staging is the sole shipped environment; a second environment is left to the operator as a customization. Anchor ` ` and per-chapter topic IDs are preserved for stable cross-references. | 
| 0.1.0 | July 2026 | Initial guidance for building the Connected Vehicle Experience on AWS. |
