This document details the targeted technical and user experience improvements included in the FastGPT 4.12.0 upgrade, focused on resolving stability issues, boosting backend performance, and refining front-end workflows.
Core Performance and Stability Optimizations
The upgrade addresses critical backend gaps to enhance long-term system stability and efficiency. Three potential memory leak issues in the codebase have been resolved to prevent gradual resource exhaustion during extended sessions. Workflow execution logic has been updated with optimized recursion checks to block infinite loops, eliminating unintended system freezes. For document processing, the document reading Worker has been modified to use SharedBuffer, removing unnecessary data copying during file parsing to speed up processing times. Vector generation and storage operations now use batch processing to reduce frequent network round trips between services. Dataset search functionality has been refined with multi-query merged computation, cutting down on redundant database queries during search workflows.
UI and Usability Updates
Front-end adjustments improve user interaction and visual consistency. The dataset selection interface has been updated for more intuitive navigation, reducing time spent locating target datasets. The login page UI has also been adjusted to align with standard design patterns for a more polished user experience.
Detailed Improvement Breakdown
