API v1 (Current)

May 2026

Quick Help embeds (data-cstar-quickhelp) now have the same SPA rebind escape hatch that CStarChat and CStarLibrary already shipped: window.CStarQuickHelp.rescan() can be called from a router lifecycle hook after a client-side navigation. Hosts mounted by an earlier route stay mounted; new hosts get discovered and bound; detached hosts get cleaned up so the internal instance list doesn't grow unbounded.
Works in two states: if Quick Help wasn't enabled or wasn't on the page at first load, the stub-level rescan() triggers a fresh init (config fetch + module load + mount). If the real api was already installed, rescan() just re-walks the DOM. Both paths are idempotent — calling rescan() repeatedly is safe.
WIDGET_VERSION bumps 5 → 6; existing customers pick up the new code on next page load.

May 2026

cstar community topics create / update / delete — full topic CRUD via the CLI. Previously only listed via cstar community topics. Bare topics still defaults to listing.
Publish-order fix: @cstar.help/js@0.16.0 needs to ship to npm before any @cstar.help/cli@0.8.3+ install will resolve. The CLI imports WEBHOOK_EVENT_CATALOG as a runtime symbol added in SDK 0.16.0; 0.15.x doesn't have it. CLI 0.8.5 keeps the same dep range; both packages ship together.

May 2026

Single-page apps (SvelteKit, React Router, Next.js App Router, etc.) can now call window.CStarChat.rescan() after a client-side route change to re-bind any newly-mounted data-cstar-* elements. window.CStarLibrary.rescan() does the same for library widgets.
The widget's MutationObserver was also widened to catch panels, message containers, input elements, and other data-cstar-* markup — previously only newly-mounted launchers triggered a re-bind.
cstar community topics create, topics update, and topics delete CLI commands now expose the topic CRUD that was previously only reachable from the dashboard. (CLI 0.8.5+; the earlier 0.8.4 used flat topic-create names but that version was never installable due to the SDK publish-order block above.)

May 2026

@cstar.help/js@0.16.0 — bare-resource returns, nine entry points (admin, auth, chat, library, community, quickhelp, proactive, webhook, webhook/node), typed error classes, per-call client.lastMeta, optional offline queue, exports WEBHOOK_EVENT_CATALOG as a runtime symbol consumed by the CLI.
@cstar.help/react@0.10.0 — chat, library, community, and dashboard providers with matching hooks; SSR-safe.
@cstar.help/svelte@0.9.0 — Svelte 5 rune-based state classes for chat, library, community, and dashboard; subpath exports dropped (single root entry).
@cstar.help/cli@0.8.5 — 21 commands including automations, seed, create, tutorial, doctor, env, config, community topics create/update/delete; 19 MCP tools.
Webhook signatures use Stripe-style format (t=<unix>,v1=<hex>) with 300s replay tolerance. Legacy sha256=<hex> is still verified for backward compatibility but no longer emitted.

March 2026

@cstar.help/js/auth — New AuthClient for customer signup, login, and session management
LibraryClient — New popularArticles() and stats() methods for public knowledge bases
All SDK packages bumped to v0.2.0 (js, cli, react, svelte)
115 tests passing across the JS SDK (13 new auth tests)
