機能

• AI AssistView
  • The WinForms AI AssistView control now provides an interface for integrating conversational AI services into Windows Forms applications. Key features include:
    • Suggestions.
    • Typing indicator.
    • Banner customization.
    • Theme support.
• Calculation Engine
  • Optimized formula engine for faster calculations - The core processes have been refined to significantly accelerate formula evaluation across large worksheets.
    • Faster SUMPRODUCT calculations - The performance of worksheets using the SUMPRODUCT formula has been significantly improved, especially when working with multiple ranges and large datasets containing over 50,000 dependent cells. The Calculation Engine now reuses previously computed values instead of recalculating them, resulting in noticeably faster processing and delivering an overall performance improvement of about 37.5%.
    • Faster IF formula processing - Performance has been significantly improved for worksheets that rely heavily on IF formulas, especially in large spreadsheets containing thousands of rows and columns. The Calculation Engine now handles logic more efficiently, reducing unnecessary processing and delivering up to 75% faster performance in scenarios with extensive IF formula usage.
• Diagram
  • Force-directed tree layout - You can now utilize a physics-based algorithm to dynamically arrange nodes for improved visualization. It attracts and repulses connected nodes to reduce overlaps and edge crossings. The result is a clean, intuitive layout that clarifies complex relationships in network analysis.
