@@ -53,8 +53,9 @@ Current temporarily frozen files:
 - `src/main/java/com/deepgram/resources/speak/v2/websocket/V2WebSocketClient.java` and `src/main/java/com/deepgram/resources/listen/v2/websocket/V2WebSocketClient.java` - forward-compat patch (both clients). Fern's generated `handleIncomingMessage` dispatcher routes any unrecognized message type to `onError` with "Update your SDK version...", which makes a benign new server control frame look fatal to a deployed client. Patched so the unrecognized-type branch is a no-op — the raw frame is already delivered via `onMessage(String)` earlier in the method, so consumers still see it. Mirrors the JS/Python SDKs' forward-compat behavior and is regression-guarded by `src/test/java/com/deepgram/SpeakV2ForwardCompatTest.java` and `src/test/java/com/deepgram/ListenV2ForwardCompatTest.java`. These two clients also carry the streaming query-param patches described in the next entry. Use the standard `.bak` swap/restore workflow during regen review; re-apply the no-op to both after regen, and unfreeze once the generator stops treating unknown frames as errors.
 - `src/main/java/com/deepgram/resources/listen/v1/websocket/V1WebSocketClient.java` and `src/main/java/com/deepgram/resources/speak/v1/websocket/V1WebSocketClient.java` (and the v2 clients above) - streaming query-param patches on the generated `connect()` builders. Two fixes: (1) multi-value serialization — array-valued params (listen: `keyterm`, `keywords`, `replace`, `search`, `tag`, `extra`, `language_hint`; speak: `tag`) were serialized with `String.valueOf(union.get())`, collapsing a `List` into one param (`keyterm=[a, b]`) instead of repeats (`keyterm=a&keyterm=b`); (2) an `additionalProperties` escape hatch — the builder exposes `additionalProperty(key, value)` for unmodeled params (e.g. `no_delay`) but `connect()` never emitted them to the URL. Both patched to route through `QueryStringMapper(arraysAsRepeats=true)`, matching the REST path. Listen V1 also forwards a parsed server `Error` to `onError` as a `ListenV1ErrorException` (carrying the typed `ListenV1Error`) when no `onErrorMessage` handler is registered, preserving the prior generic error-handler behavior. Use the standard `.bak` swap/restore workflow during regen review; re-apply after regen and unfreeze once the generator emits array params as repeats and serializes `additionalProperties` on the WS `connect()` path (tracked as an upstream Fern request).
 - Fields-less message types carrying a manual `hashCode()` patch (Fern generates `equals()` but no `hashCode()` for these, violating the Object contract): `src/main/java/com/deepgram/resources/listen/v2/types/ListenV2CloseStream.java`, `src/main/java/com/deepgram/resources/listen/v2/types/ListenV2ForceEndTurn.java`, `src/main/java/com/deepgram/resources/speak/v2/types/SpeakV2Close.java`, `src/main/java/com/deepgram/resources/speak/v2/types/SpeakV2Flush.java`, and the `AgentV1*` event types `src/main/java/com/deepgram/resources/agent/v1/types/{AgentV1ListenUpdated,AgentV1SpeakUpdated,AgentV1AgentAudioDone,AgentV1SettingsApplied,AgentV1UserStartedSpeaking,AgentV1KeepAlive,AgentV1ThinkUpdated,AgentV1PromptUpdated,AgentV1ForceEndTurn}.java`. Use the standard `.bak` swap/restore workflow during regen review; drop the patches and unfreeze all of them once the generator emits a matching equals/hashCode pair for fields-less types (tracked as an upstream Fern request).
-- `src/main/java/com/deepgram/types/DeepgramModel.java` - restores the `FLUX_RENEE_EN` constant that generator 4.18.0 dropped. The voice is live: `POST /v2/speak?model=flux-renee-en` returns 200 with valid audio, and the name resolves in the server's model registry (an invented `flux-*` name is rejected with `INVALID_QUERY_PARAMETER`), so the removal is a spec regression rather than a retirement, and dropping the constant would break 0.8.0 callers for nothing. Five touchpoints: the constant, the `Value` enum entry, the `visit()` case, the `valueOf()` case, and the `Visitor` method. **This file is unlike the other temporarily frozen ones — it receives frequent additive spec changes (4.18.0 alone added 25 constants), so on the next regen do NOT restore the `.bak` wholesale.** Diff the `.bak` against the newly generated file, carry forward every new voice, and re-apply only the `FLUX_RENEE_EN` touchpoints. Drop the patch and unfreeze once the spec lists the voice again (tracked as an upstream spec request).
+- `src/main/java/com/deepgram/types/DeepgramModel.java` - restores the `FLUX_RENEE_EN` constant that generator 4.18.0 dropped. Renee is an unlisted voice: the spec owner removed it from the catalog on purpose (#project-flux-tts, 2026-08-19), but it still synthesizes (`POST /v2/speak?model=flux-renee-en` returns 200 with valid audio), so dropping the constant would be a source break for 0.8.0+ callers over a catalog delisting alone. The constant and its `Visitor` method are marked `@Deprecated` with a note pointing callers to a listed voice. Five touchpoints: the constant, the `Value` enum entry, the `visit()` case, the `valueOf()` case, and the `Visitor` method (the constant and `Visitor` method carry the `@Deprecated` tag and Javadoc). **This file is unlike the other temporarily frozen ones — it receives frequent additive spec changes (4.18.0 alone added 25 constants), so on the next regen do NOT restore the `.bak` wholesale.** Diff the `.bak` against the newly generated file, carry forward every new voice, and re-apply only the `FLUX_RENEE_EN` touchpoints. The spec will not list the voice again, so drop the Renee touchpoints at the next major release; keep the file frozen until then for the reasons above.
 - Union default-variant fix on the agent listen-provider unions: `src/main/java/com/deepgram/resources/agent/v1/types/AgentV1UpdateListenListenProvider.java`, `src/main/java/com/deepgram/resources/agent/v1/types/AgentV1SettingsAgentListenProvider.java`, `src/main/java/com/deepgram/resources/agent/v1/types/AgentV1SettingsAgentContextListenProvider.java`. `version` is an optional discriminator, so a provider payload without it is valid (and is what 0.7.x emits), but Fern points `@JsonTypeInfo` `defaultImpl` at the empty-bodied `_UnknownValue`, so such a payload deserializes to an unknown variant carrying `null` — `getProvider()` returns `null` and re-serialization emits `{"provider":null}`, silently dropping the provider on the wire. Patched to `defaultImpl = V2Value` on each; guarded by `src/test/java/com/deepgram/AgentSettingsProviderDefaultTest.java`. Use the standard `.bak` swap/restore workflow during regen review; drop the patches and unfreeze once the generator stops defaulting unions to the empty `_UnknownValue` (tracked as an upstream Fern request).
+- `src/main/java/com/deepgram/resources/speak/v2/types/SpeakV2ConfigureFailureCode.java` makes `Visitor.visitControlCombinationInvalid()` a default method that delegates to `visitUnknown("CONTROL_COMBINATION_INVALID")`. This restores source compatibility for `Visitor` implementations written against 0.8.0–0.10.x, before the value existed (0.11.0 shipped the method as abstract and listed it as breaking), while retaining the new generated enum value. Guarded by `src/test/java/com/deepgram/RegenTypesTest.java`. Use the standard `.bak` swap/restore workflow during regen review so new failure codes from the spec are carried forward, and re-apply only the default method. Keep frozen until the next major release.

 This is called out only because the generator dropped `FLUX_RENEE_EN` in this cycle and the SDK deliberately does not ship that removal. The voice is live: `POST /v2/speak?model=flux-renee-en` returns `200` with valid audio, and the name resolves in the server's model registry (an invented `flux-*` name is rejected with `INVALID_QUERY_PARAMETER`). The constant is restored and frozen, so existing references keep compiling.

+
 `DeepgramModel` remains a forward-compatible enum, so if you need to send a value the current SDK does not model, `DeepgramModel.valueOf("some-model-name")` still works.
