Enhancements ✨​

JavaScript SDK Updates 🧩​

The JavaScript SDK has been updated to improve performance and integration. New capabilities include:

  • Transcription support
  • Volatile knowledge management

https://github.com/serenitystar-ai/serenitystar-js/tree/main/packages/sdk

Chat Widget Improvements 💬​

Transcription 🎧​

The Serenity Chat Widget now fully leverages agent-level transcription capabilities, following the agent’s default configuration to provide a more consistent and reliable audio experience.

File Uploads 📎​

Improved handling of uploaded files in the Chat Widget, with:

  • Better alignment to agent configuration
  • Improved error handling and validation

User Management 🔐​

User creation, password recovery, and account lockout actions have been updated to use a more secure authentication flow, improving overall account security.

Proxy Agents 🧭​

Proxy agents now support attaching volatile knowledge directly to the system message.
This enables similarity search to be used as part of the system definition, providing a more flexible and effective approach to RAG-style implementations.

Better Feedback for End-of-Life Models⏳​
