**Fixed incorrect conversation abandons**: Improved detection of conversation continuations, preventing premature abandons when users repeat themselves. - **Twilio information in history**: Added Twilio call details to conversation history for better tracking. - **Knowledge base redesign**: Redesigned the knowledge base interface. - **System dynamic variables**: Added system dynamic variables to use time, conversation id, caller id and other system values as dynamic variables in prompts and tools. - **Twilio client initialisation**: Adds an agent level override for conversation initiation client data twilio webhook. - **RAG chunks in history**: Added retrieved chunks by RAG to the call transcripts in the [history view](https://elevenlabs.io/app/agents/history). ### Speech to Text - **Reduced pricing**: Reduced the pricing of our Scribe model, see more [here](/docs/overview/capabilities/speech-to-text#pricing). - **Improved VAD detection**: Enhanced Voice Activity Detection with better pause detection at segment boundaries and improved handling of silent segments. - **Enhanced diarization**: Improved speaker clustering with a better ECAPA model, symmetric connectivity matrix, and more selective speaker embedding generation. - **Fixed ASR bugs**: Resolved issues with VAD rounding, silence and clustering that affected transcription accuracy. ### ElevenCreative Studio - **Disable publishing UI**: Added ability to disable the publishing interface for specific workspace members to support enterprise workflows. - **Snapshot API improvement**: Modified endpoints for project and chapter snapshots to return an empty list instead of throwing errors when snapshots can't be downloaded. - **Disabled auto-moderation**: Turned off automatic moderation based on Text to Speech generations in ElevenCreative Studio. ### Workspaces - **Fixed API key editing**: Resolved an issue where editing workspace API keys would reset character limits to zero, causing the keys to stop working. - **Optimized free subscriptions**: Fixed an issue with refreshing free subscription character limits, ### API ## New Endpoints - Added 3 new endpoints: - [Get workspace resource](/docs/api-reference/dubbing/resources/get-resource) -
