Latest release (May 2026)

26.5.0 rebuilds the Linux and macOS wheels on the GroupDocs.Viewer.CrossPlatform rendering engine, while the Windows wheel continues to use GroupDocs.Viewer. It also documents the one resulting format-support difference and refreshes the docs and the bundled AGENTS.md.

For the full release notes see GroupDocs.Viewer for Python via .NET 26.5 Release Notes.

Highlights

  • Cross-platform engine — Linux/macOS wheels now build on GroupDocs.Viewer.CrossPlatform; Windows stays on GroupDocs.Viewer. pip picks the right wheel automatically.
  • Format support by platform — every format renders on all platforms except Project (MPP, MPT, MPX) and PSD, which are Windows-only. Visio renders everywhere.
  • Python compatibility — 3.5 through 3.14 (unchanged).
  • AGENTS.md shipped inside the wheel at groupdocs/viewer/AGENTS.md for AI coding assistants.
  • No API changes — drop-in upgrade from 26.4.
