Enhancements

AI Agents

• ABP Framework 10 & .NET 10 Migration:
  The platform has been upgraded to ABP Framework 10.x and .NET 10 (LTS),
  with all dependencies updated and system components validated against
  the new versions. The upgrade also brings framework-level security gains,
  including privilege escalation prevention, single-use account tokens,
  and resource-based authorization support.

• AI Agent Optimization - Human Approval Mode:
  A new "Analyze & Suggest Improvements" option is now available on the
  AI Testing dashboard for completed evaluations in projects using AI Agents.
  Evaluation results are automatically analyzed and targeted for improvement
  suggestions are presented for review, where users can refine suggestions
  through a chat interface, selectively apply approved changes to the agent
  configurations, and validate the impact by re-running the test.

• Agent Update API with MCP Server Support:
  A new API has been introduced for updating AI Agent configurations,
  accessible through the MCP Server. Description, instructions, tool
  definitions, and collaborators can be updated for one or more agents
  in a single request, with only the modified fields included.

• HTTP Call Details in Test Chat and Conversations:
  HTTP node request and response details can now be viewed in Test Chat
  and on the Conversations page, presented in the same expandable structure
  as a tool call details. This enables users to inspect problematic
  conversations and take action accordingly, with visibility controlled
  through a new "Show HTTP call details" setting.

• Knowledge Retrieval Node:
  A new "Knowledge Retrieval" node has been introduced to the node palette
  under the AI Powered Dialog category, enabling flow designers to query a
  knowledge base directly within a flow without defining an AI Agent node.
  Retrieved document chunks are returned as node output.

• Bahasa Indonesia Language Support:
  Bahasa Indonesia (id-ID) is now available as a supported language,
  enabling AI Agents to serve customers in the APAC market.

• Voice and Digit Barge-in for LLM Nodes:
  Voice Barge-in and Digit Barge-in options are now available on AI Agent
  and RAG Agent nodes for the IVR channel, allowing end users to interrupt
  responses in scenarios where utterance nodes are not used.

Improvements

AI Agents

• Default Flow Branding Update:
  Default flow messages in newly created projects have been updated to use
  the SESTEK AI Agent branding across all languages.

• Sync in Parts Splitting Algorithm:
  The splitting algorithm in Sync in Parts has been refined to split text
  only after sentence-ending punctuation followed by a space, preventing
  unintended splits in content such as email addresses.

• Data Source Name in Knowledge Base Insights:
  Documents uploaded to the Knowledge Base are now displayed with their
  original file names on the Insights screen instead of temporary system
  paths, improving readability and traceability.

• Minor UI Improvements:
  Several minor improvements have been made to the user interface to
  enhance user experience and usability.

• Minor Bug Fixes:
  Various minor bugs have been addressed to improve overall system
  stability and performance.
