Jan 1, 2026Month: 2026-01 | Repository: ThalesGroup/fred Overview: Delivered durable backend and frontend improvements focused on scalability, reliability, and business value. Highlights include migrating data handling to PostgreSQL where feasible, strengthening attachment processing, enriching the UI, and boosting performance and observability through tooling and KPI improvements. Key outcomes: - PostgreSQL migration where possible to improve data handling and performance; accompanied by code quality enhancements. - Attachment handling enhancements: persist attachment summaries as a single chunk and add OpenSearch DuckDB-based attachments store to support dynamic agents in chat. - UI and UX improvements: per-conversation attachments display and related UI improvements, plus front-end refinements for a smoother experience. - Agent and search enhancements: improved React agent with source citations, per-document vector search, and unstructured processor usage for attachments. - Reliability, performance, and instrumentation: staging of benchmarks tooling, reuse of a single LLM client for efficiency, KPI metrics simplification, reduced log verbosity, and improved HTTP settings propagation to connectors. Top 3-5 achievements: 1) Migrated core data handling to PostgreSQL where feasible, boosting performance and data reliability (commit a3c31918662558ce4e1498eb697940e6663a3176). 2) Persisted the attachment summary as a single chunk and introduced OpenSearch DuckDB attachments store to support dynamic agents (commits d66b0ae468b55287024bc15327613a944dfcf10f and 53ed37feff0692957d4aebc1b502631e0755cdfa). 3) UI enhancements to display attachments per conversation and related UI improvements (commit bca4a439dbd449b0d6ef9eaae645317f33f4a839). 4) Stability and reliability improvements: fixed duplicate search in attached document chunks, Chromadb regression and error handling, and chat context fetch 401 error; reinforced chat stability with eager reload (commits 9ee8808da272a3c9febe8493107fe39873c6e38f, 449fbafe78ab96e634aae5f71468a48dbfde6fea, 189730a9e8eed253cec83526d7cc2d10bf41b8eb, d9463bf666a03f303ce6bd215d9b996a143ee3fb). 5) Performance, tooling, and instrumentation: added benchmarks tooling to improve Fred agent performance, reused a single LLM client for efficiency, KPI metrics simplification, and improved logging and HTTP settings propagation (commits d6503bc8ade469b51843d235a198180281edfcac, 9f808dda641b1779f60f5627a5e9de9efa5fdb0d, c7830c97f399ba3ae5fbc5acaeeba6f50b113c0d, 3cefd583412146c00d40ec9f075e38ee4c76470b, ce284c252643baa62166099b89785c72c6b593a0).

Nov 1, 2025November 2025 (ThalesGroup/fred) delivered broad business-value across agent lifecycle, data ingestion, UI quality, and deployment readiness. Key features implemented include robust session management with caching to reduce memory footprint and improved in-memory concurrency controls, along with session restoration and enhanced logging for traceability. The ingestion pipeline was strengthened with asynchronous processing, data lineage UI improvements, and lightweight document processors (PDF/CSV/DOCX/PPTX), complemented by OpenSearch integration. PPTX generation reliability was stabilized through an upgrade to latest LangChain/LangGraph dependencies and expanded runtime guidance for developers. User-facing enhancements include welcome messages, per-session attachments management, and improved document retrieval controls with richer logging. New capabilities were added in the travel/eco domain and graph-based workflows (Travel POI Agent, EcoAdvisor CO2 Agent, Neo4j connector with library processing UI), supported by configuration loading refactor and updated release/deployment templates. These changes improve reliability, time-to-value, security, and observability while enabling richer user experiences and scalable data processing.
