+## [4.0.0] - 2026-11-10
+### Breaking Changes
+- **`SquadMemberDto.assistant`** and **`TesterPlan.assistant`** — type changed from `CreateAssistantDto` to `TransientAssistantDto`; update any code constructing or reading these fields to use `TransientAssistantDto`.
+
+### Added
+- **`TransientAssistantDto`** — new interface for configuring a full transient (non-persisted) assistant inline, covering transcriber, model, voice, hooks, credentials, and all standard assistant settings.
+- **`client.guardrailPacks`** and **`client.guardrailRules`** — new `GuardrailPacksClient` and `GuardrailRulesClient` for browsing guardrail packs and rules, with list, paginated, and single-fetch methods; supporting sort enums also added.
+- **`CallHealthDashboard*` type family** — 40+ new interfaces and enums for monitoring assistant goal performance, issue tracking, call availability, coverage reporting, and triage actions.
+- **`SimulationOnboarding*`** and **`TrafficTab*` type families** — new types supporting AI-assisted simulation suite generation/onboarding workflows and per-version traffic analytics dashboards.
+- **New enum values and fields across several types** — including `SonioxTranscriber.agentTextInputEnabled`, `WorkflowOpenAiModel.reasoningEffort`, `TurnLatency.unmeasured`, `CartesiaVoiceModel` Sonic 3.6 variants, Odia/Urdu language codes, Reson8 transcriber/credential variants, and new `CallEndedReason`/`ServerMessageStatusUpdateEndedReason` values covering guardrail, Reson8, ElevenLabs, and Cartesia failure modes.

 ## [3.0.0] - 2026-10-08
 ### Breaking Changes
 - **`ToolPinnedConflictResponseDtoError`** and the standalone **`ToolPinnedConflictResponseDto.error`** field have been removed from the SDK. The API still returns `error: "tool_pinned"` in pinned-tool HTTP 409 responses. After validating or narrowing the error body, use **`Vapi.ConflictErrorBody`** or **`Vapi.ConflictErrorBody.ToolPinned`** to read its `error` discriminator. Replace the removed constant with the literal `"tool_pinned"`. The `message` field contains the human-readable reason and does not replace the discriminator.
