For AI agents: a documentation index is available at the root level at /llms.txt. Append /llms.txt to any URL for a page-level index, or .md for the markdown version of any page.
Structured procedures compile on save and publish: Update agent and Create agent draft now compile and validate structured procedures automatically. Integrations no longer need to call the compile endpoint or manually update the generated workflow. Invalid procedures return per-procedure errors as 400 procedure_validation_failed. Agents without structured procedures are unaffected.
Compile procedures endpoint is legacy: Compile procedures is marked legacy and should not be used by new integrations. It remains available for existing callers.
Merge proposals: Merge proposals are available in alpha. Teams can open a proposal for an agent branch, review configuration changes and test results, leave comments or approval decisions, and merge approved changes into a target branch. See Merge proposals.
SDK releases
JavaScript SDK
v2.71.0 - Added clients for agent merge proposals, deployment history, test invocation cancellation and Speech Engine duplication. The release also adds triage ticket priorities and sorting, batch call export limits, gpt-6.1-sol, claude-sonnet-5-5, Eleven v4 agent voice models and current agent configuration types.
Python SDK
v2.71.0 - Added clients for agent merge proposals, deployment history, test invocation cancellation and Speech Engine duplication. The release also adds triage ticket priorities and sorting, batch call export limits, gpt-6.1-sol, claude-sonnet-5-5, Eleven v4 agent voice models and current agent configuration types.
Swift SDK
v3.4.0 - Dynamic variables now preserve native JSON types when sent in conversation initiation data.
Packages
@elevenlabs/client@1.26.0, @elevenlabs/react@1.16.0, @elevenlabs/react-native@1.2.28 and @elevenlabs/types@0.24.0 - Added realtime Speech to Text transcript editing through transcriptEdit, the edited_transcript event and React’s onEditedTranscript callback. React now forwards filterBackgroundAudio to realtime sessions. The client also exports MessagePayload and uses stable response IDs to prevent duplicate agent replies.
@elevenlabs/convai-widget-core@0.18.3 and @elevenlabs/convai-widget-embed@0.18.3 - Added image previews and download links for agent message attachments, including attachment-only replies. Stable response IDs prevent duplicate replies, and text-only conversations now use a stop control with an End chat tooltip.

List merge proposals - GET /v1/convai/agents/{agent_id}/merge-proposals - List proposals with status, source branch, target branch and text filters, plus cursor pagination.
Get a merge proposal - GET /v1/convai/agents/{agent_id}/merge-proposals/{merge_proposal_id} - Retrieve a proposal and its review, comment and outcome details.
Update a merge proposal - PATCH /v1/convai/agents/{agent_id}/merge-proposals/{merge_proposal_id} - Update its title, description or requested reviewers, or close it without merging.
Review a merge proposal - POST /v1/convai/agents/{agent_id}/merge-proposals/{merge_proposal_id}/reviews - Submit an approved or changes_requested decision with an optional comment.
Comment on a merge proposal - POST /v1/convai/agents/{agent_id}/merge-proposals/{merge_proposal_id}/comments - Add a Markdown comment of up to 4,096 characters.
Merge a merge proposal - POST /v1/convai/agents/{agent_id}/merge-proposals/{merge_proposal_id}/merge - Merge the source branch and optionally control forced conflict resolution and source branch archival.
List agent deployments - GET /v1/convai/agents/{agent_id}/deployments - List current and historical branch traffic splits with page-based pagination.
Cancel a test invocation - POST /v1/convai/test-invocations/{test_invocation_id}/cancel - Cancel a running test invocation.
Speech Engine
Duplicate a Speech Engine - POST /v1/speech-engine/{speech_engine_id}/duplicate - Duplicate a Speech Engine and optionally assign the copy a new name.
Added gpt-6.1-sol and claude-sonnet-5-5 to the LLM enum.
Added eleven_v4 and eleven_v4_turbo to the conversational TTS model options. The default changed from eleven_flash_v2 to eleven_v4_turbo.
Agent transfers and standalone workflow agent nodes add optional preserve_voice_settings (boolean, default false) to retain the base voice, TTS model and voice settings after a transfer.
Skip-turn tool configurations add optional wait_timeout_secs (number, default -1). A value of -1 keeps the agent silent until the caller speaks.
Post-call webhook configurations add optional exclude_transcript (boolean, default false) to omit turn-by-turn transcripts from JSON transcription webhooks.
Conversation history redaction configurations add optional excluded_data_collection_ids (string array, maximum 50) to preserve selected extracted values while redacting their rationales.
Client tool response_timeout_secs now accepts -1 to wait indefinitely when expects_response is enabled.
Added optional priorities (array) with low, medium, high and urgent values.
Added sort_by with created_at and priority values; the default is created_at.
Ticket responses now require title, nullable priority, and a priority_changes array. Ticket creation and update requests can set priority, and ticket status adds cancelled.
List tools - Added optional nullable used_by_agent_id (string) to return tools referenced by an agent’s main branch.
Export batch call results - Added optional nullable limit (integer, minimum 1) to export only the first recipients as a column preview.
