Änderungsprotokoll

• Fast LLM service tier: Agents and workflow overrides accept service_tier (standard or fast) on supported models. List LLMs returns available_service_tiers for each model, and the LLM usage calculator accepts service_tier.
• Knowledge base crawl exclusions: Create crawl job accepts exclude_patterns, and the whole-website crawl dialog adds an Exclude patterns field. Matching URLs are skipped.
• Procedures analytics: The Procedures tab on the agent analytics dashboard is available to every workspace. Its Procedure invocations chart shows how often each procedure runs over time, grouped by procedure or by agent, and its tooltip shows whether a procedure is structured or free-form.
• Start procedures at conversation start: Conversation initiation client data accepts start_procedure_ids, up to five free-form procedures that start when the conversation starts. The agent must have enable_procedure_ids_from_client enabled; structured procedures and unknown IDs fail the conversation start.
• Structured procedure steps: Structured procedures can use the end_procedure system tool as a step, and the End step is relabeled End conversation. Sub-procedure and end steps now compile to system tool nodes, so agents start and end the intended procedure more reliably.
• Channel integrations out of alpha: The Slack, Telegram, Custom Channel and Intercom integrations are no longer in alpha. Freshdesk remains in alpha.
• Slack thread replies: The Slack Channel Message trigger adds a Respond to setting (response_mode), so an agent can keep replying in a thread after a single mention. Mentioning the agent with only stop, mute or quiet silences it in that thread until it is mentioned again, and events that Slack delivers twice get one reply.
• Test run names: Run tests accepts an optional name, which test invocations and their summaries return. PATCH /v1/convai/test-invocations/{test_invocation_id} renames a run, and setting name to null restores the generated title.
• Branch descriptions: Branch descriptions can be edited from the branches table with Update branch (description, up to 4,096 characters) and appear in the version tooltip and version graph.
• Agent duplication keeps traffic splits: Duplicating an agent copies its live traffic split across the copied branches. The resulting deployment records duplicate as its deployment source.
• Delete environment variables: DELETE /v1/convai/environment-variables/{env_var_id} deletes an environment variable.
• Widget fullscreen on mobile: Widget configuration adds mobile_fullscreen (default true), with a Fullscreen on mobile switch in the dashboard. Set it to false to keep the compact layout on phones. See Widget.
• Issues: Triage is renamed Issues in the agents dashboard, and triage tickets are now called issues. Every QA comment and flag_issue_for_review call opens its own issue, and an issue can be reopened while the conversation has another open issue. The API endpoints keep their triage-tickets paths. See Triage.
• Prompt caching guidance: The system prompt editor flags system variables that change on every turn and prevent prompt caching, and Spotlight adds an Improve prompt caching recommendation for affected agents.
• Realtime voice mode: Switching an agent to Realtime voice mode in the dashboard now selects Eleven Realtime v1 Max. Realtime agents always run tool calls in parallel, so the Parallel tool calling toggle is removed from Realtime model settings. See Realtime models.
• Analytics: Workflow analytics can be filtered by channel, and the Guardrails tab is shown to all users.
• Analysis LLMs: claude-sonnet-5-5 can be selected as the analysis LLM for evaluation criteria and data collection, both for the agent and per item. Agents on Claude Sonnet 5.5 can also set reasoning effort to none.
• Conversation cost: Conversation charging adds voice_surcharge_charge, the credits charged as the voice actor reward for the Voice Library voices a conversation used. It is not included in cost.
• Call duration and billing: Call charges and stored call duration stop when the call ends, so teardown time after the call is no longer billed or counted. Calls no longer continue for up to 50 seconds after ending when a knowledge base lookup is in progress.
• Telephony: SIP trunk calls forward the User-To-User (UUI) header to the conversation initiation webhook. API keys with an IP allowlist now authenticate on the Genesys, Avaya, AudioCodes and Amazon Connect connector WebSockets. Batch call recipients whose call cannot be placed are marked failed instead of staying dispatched.
• Observability: OpenTelemetry post-call webhook agent turn spans add elevenlabs.rag.chunks and elevenlabs.rag.used_chunk_ids, matching the JSON post-call webhook. See OpenTelemetry traces.
• Guardrails: In voice conversations, the prompt injection guardrail now evaluates the user turn being answered instead of the agent’s previous message. Conversations on asynchronous channels such as Zendesk, Intercom and Custom Channel that a guardrail blocks now report the guardrail as the termination reason.
• Zero Retention Mode: Synthetic voice detection is skipped for conversations in Zero Retention Mode.
• WhatsApp: WhatsApp conversations resumed by a reply to a batch call template keep their batch_call metadata and batch ID.
• Phone number secrets: Workspace secrets used as a Twilio auth token or an Exotel API token on a phone number show as in use and cannot be deleted while the number depends on them.
• Fixes: Text conversations end as soon as the end_call tool runs instead of waiting for the next user message. Voice agents no longer go silent when a turn is cancelled before any audio is sent. The soft timeout no longer fires right after the first message or after tool calls on Eleven v4 voices. Realtime agents with sub-agent, agent tool or prompt say nodes that inherit the LLM can be saved and published. Agent tools that use OAuth2 connections no longer fail with expired tokens when the provider rotates refresh tokens. The nemotron-35-super-vl-nvfp4 context limit is raised from 64,000 to 131,072 tokens.

• Clone strength: clone_strength (0 to 1) in Text to Speech voice_settings and Text to Dialogue settings controls how closely a Professional Voice Clone fine-tuned for a v4 model follows its samples. The recommended value for most use cases is 0. Edit voice settings stores clone_strength and Get voice settings returns it.
• PVC and IVC on v4 dialogue: On the Text to Dialogue endpoints, clone_strength now decides whether a v4 PVC runs as a PVC or an IVC, and use_pvc_as_ivc is deprecated.

• New endpoint paths: Voice Changer is documented at POST /v1/voice-changer/{voice_id} and POST /v1/voice-changer/{voice_id}/stream. The /v1/speech-to-speech/{voice_id} paths keep working but are deprecated and removed from the API reference. The Python and JavaScript SDKs call the new paths from v2.75.0, and the SDK method names are unchanged for now. In the next major SDK version, client.speechToSpeech will be deprecated in favor of client.voiceChanger to match the endpoint. See Voice changer.

• Expiring service account API keys: Service account API keys accept expires_at_unix on create and update, between 15 minutes and 90 days in the future. Later expiries are rejected with 400 invalid_api_key_expiry. On update, pass "clear" to remove an expiry.
• Group concurrency limits enforced: The workspace group concurrency limits (group_concurrency_limit, group_dubbing_concurrency_limit and group_music_concurrency_limit) are enforced for Text to Speech, Voice Changer, Music and Dubbing requests.
• Voice cloning permissions: Members without the Create instant voice clone or Create professional voice clone permission can no longer create clones, even with general voice access.
• SCIM group seat types: Workspaces that use SCIM without SCIM routing can assign a seat type to SCIM-synced groups from the Groups page.
• Fixes: Delete invite returns 404 invite_not_found for an invite that does not exist, instead of a 500 error.

• Shorter realtime silence thresholds: Realtime Speech to Text honors vad_silence_threshold_secs values below 0.5 seconds, which were previously treated as 0.5. The minimum accepted value is lowered from 0.3 to about 0.19 seconds.
• Webhook retries: Transcription and error webhooks are retried on failure when the webhook’s retry setting is on. See Speech to Text webhooks.

• Legacy endpoints deprecated: The /v1/dubbing endpoints outside /v1/dubbing/project, including Dub a video or an audio file and List dubs, are marked deprecated in the API reference.
• Transcript downloads: The dubbing project menu can download target language transcripts as JSON, and as WebVTT subtitles for recent dubs.

• Media folders: Workspace library files can be organized into folders in the Studio media browser.
• Video clip actions: Video clips offer voice changer and voice isolator actions.
• Video to music: Studio’s video to music workflow uses Music v2.5 by default.

• Retired models: Image & Video and Flows requests for a retired model fail before generation with a 410 model_retired error that names the replacement model. Flows preflight reports the error on the affected node.
• Fixes: Generations wait for a just-uploaded reference asset to finish processing instead of failing.

• Fixes: Cantonese Professional Voice Clone samples are no longer rejected when language detection reports Chinese, and adding PVC samples no longer fails with a 500 error when language detection is unavailable.

• Minimum charge: Text to Speech and Speech to Text requests priced below one credit are charged one credit, and refunds return exactly the credits that were charged.
• Business plan image and video pricing: Business plans on the current pricing pay the same image and video credit rate as other self-serve plans, about 17% fewer credits per image and per video second than before.

• OAuth scope: OAuth clients can request the realtime_translation scope.

JavaScript SDK

• v2.75.0 - client.speechToSpeech.convert and client.speechToSpeech.stream now call POST /v1/voice-changer/{voice_id} and its /stream path. Added client.environmentVariables.delete, client.conversationalAi.tests.invocations.update for renaming a test invocation, and an optional name on client.conversationalAi.agents.runTests. Also adds serviceTier on the LLM usage calculators, excludePatterns on knowledge base crawl jobs, expiresAtUnix on service account API keys, cloneStrength in voice settings, startProcedureIds in conversation initiation client data and the widget mobileFullscreen setting. The legacy dubbing list, create, get and delete methods are marked deprecated, and the branch rebase request type BranchesRebaseRequest is renamed to BodyRebaseABranchOntoMainV1ConvaiAgentsAgentIdBranchesBranchIdRebasePost.

Python SDK

• v2.75.0 - Added the callback_disconnect option to Conversation and AsyncConversation. It receives a DisconnectionDetails with a reason of "user", "agent" or "error", plus the WebSocket close code and reason when available, and replaces the deprecated callback_end_session. The regenerated client moves client.speech_to_speech to the /v1/voice-changer paths and adds client.environment_variables.delete, client.conversational_ai.tests.invocations.update and the same new parameters as JavaScript SDK v2.75.0.

Android SDK

• v0.13.0 - agent_tool_request is now handled as a notification event instead of a client tool call, so client tools no longer run twice, the first time without parameters. The SDK also no longer crashes when a client tool answers after the connection has closed.

ElevenLabs CLI

• v1.7.1 - say uses eleven_v4 and new agent templates use eleven_v4_turbo by default. Fixes onboard sign-in on Windows and when the token cannot be saved to the keychain.

Packages

• @elevenlabs/client@1.29.0 and @elevenlabs/react@1.19.0 - Added the onAudioAlignmentPlayback callback, called with { event_id, alignment } when an aligned audio chunk starts playing, for syncing text with speech. It is not called on WebRTC connections.
• @elevenlabs/client@1.30.0 - Added the opt-in stripAudioTags session option, which removes audio tags such as [laughs] from agent messages passed to onMessage and onAgentResponseCorrection, and exports the stripAudioTags helper. Stripped text no longer lines up with onAudioAlignment timings.
• @elevenlabs/client@1.31.0, @elevenlabs/types@0.26.0 and @elevenlabs/react@1.20.0 - Added overrides.tts.modelId for a per-conversation TTS model override. Realtime Speech to Text emits RealtimeEvents.AUDIO_STARTED once the first microphone audio frame is sent, and useScribe in microphone mode reports connected only from that point.
• @elevenlabs/convai-widget-core@0.21.0 and @elevenlabs/convai-widget-embed@0.21.0 - Voice call transcripts are revealed in step with the agent’s speech, and an interrupted reply keeps only what was said. Resuming a persistent text conversation no longer asks the user to accept the terms again.
• @elevenlabs/convai-widget-core@0.21.1, 0.21.3 and 0.21.4 - Text chat shows typing dots while the agent prepares its reply. Rich content carousels show a page indicator, stay clickable after the conversation moves on, and appear in voice calls while the agent is still speaking. On screens narrower than 768px the chat opens fullscreen; add mobile-fullscreen="false" to the embed to keep the compact layout.
• @elevenlabs/react-native@1.2.31, 1.2.32 and 1.2.33 - Updated to the latest @elevenlabs/client and @elevenlabs/react releases.
