ElevenAgents

Per-agent sentiment analysis: Platform settings add optional sentiment_analysis (SentimentAnalysisSettings) for post-call sentiment scoring configuration per agent.
Auto-translate transcripts: Platform settings add optional auto_translate_transcript_to_app_language (boolean) to translate conversation transcripts to the viewer's app language in history.
Nested agent transfers: Workflows add push, pop and replace operations for nested agent transfers, with enable_nesting and return_when_nested controls for returning to a parent workflow.
Backchannel detection: Transcript user-turn models add optional ignored_as_backchannel (boolean) to mark utterances filtered as backchannels.
Auxiliary conversation audio: Get conversation responses add required has_auxiliary_audio (boolean) alongside existing audio flags.
MCP environment scoping: MCP server and tool routes add optional environment query parameter (defaults to production) on list tools, get tool, create tool config and update tool config endpoints.
Tool call sound override: Tool and MCP override schemas allow tool_call_sound: "off" to silence per-tool call sounds while inheriting server defaults when unset.
Twilio SMS routing: Twilio phone-number import requests add optional enable_sms (boolean, default on) to control inbound SMS routing during number setup.
User sentiment sorting: List users adds optional sort_direction and supports sorting by average_sentiment_score.
Knowledge base external sync: External sync schemas rename ExternalSyncType to ExternalSyncProvider, add sync job trigger and type enums with KbExternalSyncJob, and folder responses can include active_sync_job for in-flight or terminal sync status.
TTS latency setting deprecation: optimize_streaming_latency on agent TTS settings is marked deprecated and documented as a no-op.

Workspaces

Create service accounts: Added Create service account (POST /v1/service-accounts) with optional default_sharing_groups (DefaultSharingGroupConfig) for programmatic service-account provisioning.
List workspace members: Added Get workspace members (GET /v1/workspace/members) returning WorkspaceMemberResponseModel entries with user id, email, seat status, owner and locked flags. Service accounts are excluded.
Invite credit caps: Workspace invite payloads (single and bulk) add optional usage_limit for a monthly credit cap on invitees.
