Core New Features

This release delivers foundational platform updates:

  • File upload configuration overhaul: Image upload functionality is now governed by system-wide settings instead of relying on vision model availability.
  • AI chat and tool call nodes now include an Enable image recognition toggle. When enabled, the system automatically extracts images from chat uploads and image URLs embedded in user questions.
  • New document parsing node for automated workflow processing.
  • Bulk deletion option for all conversation starters.
  • QA splitting now supports custom chunk sizes, with an optimized fix for GPT-4o-mini generating minimal output when using large chunks.

Commercial Edition Enhancements

Commercial tier users gain expanded management tools:

  • Team notification account binding to receive critical platform alerts
  • Dataset collection tagging for organized, tag-based dataset categorization
  • Dataset search node filtering by tags and file creation date
  • Ability to transfer app owner permissions between authorized users

Usability and Performance Improvements

Two key updates to streamline platform usage:

  • Lazy loading for chat messages to reduce unnecessary network data transfer
  • Cleared file selection cache to allow re-selection of the same file without prior selection conflicts
