Version 2.11.1 Release Notes

Released on January 18, 2025 - This release brings powerful AI search capabilities to the document library, complete document versioning UI, and significant performance improvements.

​
🎯 Highlights

AI Search

Semantic search with document name display

Document Versioning

Full version history with diff visualization

68% Faster

Major performance optimizations

​
✨ AI Search in Document Library

The document library now features a powerful AI-powered search capability that provides intelligent answers based on your documents.

​
Key Features

Switch between traditional keyword search and AI-powered semantic search with a single click. The AI search uses advanced natural language processing to understand the intent behind your queries.
// Toggle between search modes
const [aiSearchEnabled, setAiSearchEnabled] = useState(false);
No more cryptic document IDs! The AI search now displays actual document names as clickable buttons, making it easy to identify and access source documents.Before: 099fdd05..., 3d7c39a7... After: Project Requirements.pdf, API Documentation.md
Get instant AI-generated answers with a 500ms debounce for optimal performance. The system intelligently processes your query and returns relevant information from your documents.
Every AI answer includes clear source attribution with clickable document links. Click any source document to instantly open it in the preview modal.

​
How It Works

  1. Enable AI Search: Click the sparkles icon in the library search bar
  2. Type Your Query: Enter a natural language question
  3. Get Instant Answers: AI analyzes your documents and provides relevant answers
  4. Explore Sources: Click on source documents to view the full content

​
Technical Implementation

// Enhanced askKnowledgeBase with document name fetching
export async function askKnowledgeBase(
  userId: string,
  query: string,
  projectUuid?: string
): Promise<{
  answer?: string;
  documents?: Array<{ id: string; name: string }>;
  sources?: string[];
}>

​
📚 Document Versioning UI

Complete user interface for document version management with visual diff tracking.

​
Version History Features

  • Timeline View
  • Change Tracking
  • Version Comparison
  • Chronological version display
  • Expandable version details
  • Visual indicators for current version
  • Model attribution badges

​
Version Metadata

Each document version includes:
  • Version Number: Sequential versioning
  • Created By: AI model attribution (name, provider, version)
  • Timestamp: Creation time with relative display
  • Change Summary: Brief description of modifications
  • Content Diff: Additions, deletions, and modifications

​
⚡ Performance Optimizations

Major performance improvements across the document preview system.

​
Technical Improvements

Replaced 13 individual state variables with a single useReducer for centralized state management.
// Before: 13 useState hooks
// After: Single useReducer
const [state, dispatch] = useReducer(documentReducer, initialState);
Implemented dynamic import caching to prevent redundant module loading.
const importCache: Record<string, any> = {};
const getDynamicImport = async (key: string, importFn: () => Promise<any>) => {
  if (!importCache[key]) {
    importCache[key] = await importFn();
  }
  return importCache[key];
};
Comprehensive memoization with useMemo, useCallback, and React.memo for optimal rendering performance.
Implemented React.lazy and Suspense for code splitting and on-demand loading of heavy components.

​
🔧 API Enhancements

​
Enhanced RAG Query Response

The RAG API now returns structured data with document metadata: 
{
  "results": "Your AI-generated answer...",
  "sources": ["doc1.pdf", "doc2.md"],
  "document_ids": ["uuid1", "uuid2"],
  "documents": [
    { "id": "uuid1", "name": "Project Requirements.pdf" },
    { "id": "uuid2", "name": "API Documentation.md" }
  ]
}

​
New Hooks

useKnowledgeBaseSearch: Complete hook for AI search functionality 
const {
  query,
  answer,
  documents,
  sources,
  isLoading,
  error,
  setQuery,
  clearAnswer
} = useKnowledgeBaseSearch();

​
🐛 Bug Fixes

  • Fixed document ID display showing cryptic identifiers instead of names
  • Resolved null safety issues in document ID handling
  • Fixed memory leaks in document preview component
  • Corrected AbortController cleanup in useEffect hooks
  • Fixed XSS vulnerabilities with DOMPurify implementation

​
🌍 Internationalization

All new features include complete translations for:
  • English (en)
  • Turkish (tr)
  • Chinese (zh)
  • Hindi (hi)
  • Japanese (ja)
  • Dutch (nl)

​
