+## 0.0.28 — 2026-05-07
+
+### Breaking
+
+- **`@ngaf/langgraph`** — removed the `messagesKey` option from `AgentOptions`. The messages slot is now fixed at the `messages` state key, matching the LangGraph Python/JS conventions. Consumers passing `messagesKey: 'customKey'` should rename the upstream graph state slot to `messages` instead. (Landed in #202; this entry backfills the release notes.)
+
+### Fixed
+
+- **`@ngaf/langgraph`** — `RemoveMessage` wire-shape now includes `role` + `content` so checkpoint rollback (used by `regenerate()`) round-trips correctly through the LangGraph SDK serializer.
+
+---

 ## 0.0.22 — 2026-05-04

 **Goal:** Add the hero redesign, agentic docs infrastructure, and MCP server package described in the two approved specs, layered on top of the base website plan (`2026-03-18-website.md`).

 **Goal:** Build the Angular Agent Framework Next.js marketing and documentation website — landing page, pricing, docs, live Angular Elements demo — using the indigo-blue neon brand from `docs/superpowers/specs/2026-03-18-website-branding-design.md`.

 # LangGraph `agent()` Unification Implementation Plan
 
 > **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development.
+>
+> **⚠️ Path note (post-PR #203):** API docs are now generated per-library to `apps/website/content/docs/{lib}/api/api-docs.json` (script: `apps/website/scripts/generate-api-docs.ts`). The legacy `apps/website/public/api-docs.json` referenced below has been removed.
 
 **Goal:** Refactor `@ngaf/langgraph` so `agent({...})` returns a unified `LangGraphAgent` (extends `AgentWithHistory`) preserving all `AgentRef` public surface. Delete `toAgent(ref)`. Migrate ~23 cockpit components and ~20 website doc files.
