• Fixed engine stability issues that could cause orphaned browser processes, unexpected crashes, and rendering failures under heavy load or constrained CPU environments
• Fixed an issue where PDF redaction could leave partial-character artifacts or remove excess content due to inaccurate text bounding boxes
• Fixed an issue where ImageToPdfConverter.ImageToPdf could generate blank PDFs for image filenames containing both spaces and multiple dots
• Fixed an issue where multi-page TIFF conversion did not preserve per-page orientation and resolution for mixed-orientation PDFs
