 ## Recent Updates
 
+### 2026-03-05: v0.3.2 — Updated API Spec from elevenlabs-python (SDK #740)
+
+Updated `lib/elevenlabs/spec.json` by running the extraction script against the latest elevenlabs-python SDK (commit 78ed67e, SDK regeneration #740 — March 2026).
+
+**New Operations:**
+- `conversational_ai.agents.enable_versioning` — enable versioning on a conversational AI agent
+- `conversational_ai.agents.enable_versioning_if_not_enabled` — conditionally enable versioning if not already enabled
+- `music.upload` — upload audio files for use in music workflows
+- `music.extract_composition_plan` — extract a composition plan from an audio file
+- `pronunciation_dictionaries.rules.set` — replace the full rules set on a pronunciation dictionary
+
+**New Ruby access patterns:**
+```ruby
+client.conversational_ai.agents.enable_versioning(agent_id: "agent_123")
+client.conversational_ai.agents.enable_versioning_if_not_enabled(agent_id: "agent_123")
+client.music.upload(file: ElevenLabs::Upload.from_path("track.mp3"))
+client.music.extract_composition_plan(file: ElevenLabs::Upload.from_path("track.mp3"))
+client.pronunciation_dictionaries.rules.set(pronunciation_dictionary_id: "dict_123", rules: [...])
+```
+
+**New Types:**
+`CheckServiceAvailabilityParams`, `CreateAssetParams`, `CreateClientAppointmentParams`, `CustomGuardrailsConfigInput`, `CustomGuardrailsConfigOutput`, `DeleteAssetParams`, `DeleteCalendarEventParams`, `GetClientAppointmentsParams`, `GuardrailExecutionMode`, `ListCalendarEventsParams`, `MusicUploadResponse`, `RequiredConstraint`, `RequiredConstraints`, `StudioAgentSettingsModel`, `StudioAgentToolSettingsModel`, `TelephonyCallConfig`, `UpdateAssetParams`, `UpdateCalendarEventParams`, `VoiceStatisticsResponseModel`
+
 ### 2026-03-05: v0.3.1 — HTTP Redirect Following
 
 The HTTP client now automatically follows `3xx` redirects when the server returns a redirect response. This means requests that hit moved or redirected endpoints will transparently re-issue to the new location without any change to your calling code.
