IronXL for Python via .NET 2026.7.0.230 giu 2026
Funzionalità
  • Added support for extracting and accessing PDF Optional Content Groups (OCG/layers), including layer hierarchy, visibility, and object-level layer metadata.
  • Added ChromePdfRenderOptions.CssPageRulePolicy and header/footer overlap detection options to improve margin handling and prevent content overlap when rendering or modifying PDFs.
  • Enhanced PDF scanning reliability by removing shellcode hash-based detection rules that could cause inconsistent false-positive results.
  • Enhanced render timeout handling by detecting stalled PDF generation operations and returning clearer, more actionable error messages.
  • Updated internal dependencies.
Correzioni
  • 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.
  • Fixed an issue where Cleaner.SanitizeWithSvg could add an extra page and corrupt non-ASCII text in sanitized PDFs.
  • Fixed an issue where PDF signature timestamps could display an incorrect timezone offset during daylight saving time (DST).
IronXL for Python via .NET 2026.6.0.1Versione principale25 mag 2026
Funzionalità
  • Added support for 40+ modern Excel _xlfn.* functions, improving EvaluateAll() compatibility with Microsoft 365 workbooks.
  • Updated internal dependencies.
Correzioni
  • Known Issues:
    • Range.Value = <python int> stores an empty string instead of the integer (formulas reading the cell resolve to 0). Use IntValue or a Python float as a workaround; .NET is unaffected.
