Each entry is sectioned by product (ElevenAgents, Music, Creative, API) and carries an explicit "API changes" block enumerating new endpoints, updated endpoints and schema changes, plus a "SDK releases" block linking the matching GitHub release tag for every first-party SDK. The breaking-changes policy at /docs/eleven-api/resources/breaking-changes-policy states the changelog is published "on a weekly cadence" — the observed dates confirm it. scheme: date-based (no semantic API version) scheme_note: | The API itself is path-versioned at /v1 and carries no dated or header version. The published OpenAPI reports info.version "1.0". Releases are identified by DATE in the changelog, and by semver only at the SDK level. current_api_version: v1 openapi_info_version: '1.0' cadence: weekly first_entry: '2024-10-13' latest_entry: '2026-09-14' entry_count_observed: 100 entry_count_note: the llms.txt index listed 100 dated entries running 2024-10-13 to 2026-09-14 when read on 2026-09-17. index_machine_readable: https://elevenlabs.io/docs/changelog/llms.txt entry_format: markdown, one page per date, available as .md entries: - date: '2026-09-14' url: https://elevenlabs.io/docs/changelog/2026/9/14 breaking: false additions: - 'New endpoint: POST /v1/convai/agents/{agent_id}/hold-audio (upload agent hold audio)' - 'New endpoint: DELETE /v1/convai/agents/{agent_id}/hold-audio' - Optional platform_settings.queueing_config on create/get/update agent - Optional include_draft on create agent branch - Music endpoints accept music_v2_5 - Agent LLM configuration accepts gemini-3.8-flash highlights: Call queueing and hold audio for agents at their concurrency limit; queued callers receive queue_status events.
