Latest release (September 2026)

26.9.0 upgrades the GroupDocs.Viewer engine from 26.4 to 26.8. MS Project files now render on Linux and macOS, Word documents gain page numbering and resolution options, and the Linux and macOS packages no longer need libgdiplus. Nothing is removed or renamed.

For the full release notes see GroupDocs.Viewer for Python via .NET 26.9 Release Notes.

Highlights

  • MS Project on every platform — MPP, MPT and MPX render on Linux and macOS as well as Windows. On Linux they need the Microsoft core fonts (ttf-mscorefonts-installer).
  • Page numbers for Word documents — WordProcessingOptions.page_number_location with the new WordsPageNumberLocation enum.
  • Resolution for Word documents — WordProcessingOptions.horizontal_resolution / vertical_resolution set the DPI of PNG and JPEG output (72 – 600, default 96).
  • No libgdiplus — the Linux and macOS packages never call it; drop it from your images.
  • One Python API everywhere, with docstrings and code examples throughout.
  • Python 3.5 – 3.14 — 3.5 to 3.7 work again.
  • Patched .NET runtime — the embedded runtime moves from 10.0.0 to 10.0.12, with Microsoft’s servicing and security fixes.
  • Wheels state the system they need — Linux x64 with glibc 2.27+, macOS 12+; pip 20.3 or newer refuses an older system up front.
