Hi everyone,

GroupDocs.Signature for Python via .NET version 26.10 is now available on PyPI.

:link: Full release notes: GroupDocs.Signature for Python via .NET 26.10 Release Notes
:package: PyPI: groupdocs-signature-net==26.10.0
:books: Docs: GroupDocs.Signature for Python via .NET

Highlights

  • Python functions can be used directly for page and signature preview callbacks via PreviewOptions.
  • Plain Python objects can implement ILogger, IDataEncryption, and ICustomSignHash.
  • Full support for Python 3.14 without code changes.
  • Engine upgraded to v26.9 and embedded .NET runtime updated to 10.0.12.
  • 18 members renamed to match .NET spelling (e.g., z_order → zorder, x_ad_es_type → xad_es_type).
  • Specific exceptions (GroupDocsSignatureException, IncorrectPasswordException, PasswordRequiredException) replace generic RuntimeError.
  • Assigning an undefined attribute now raises AttributeError.
  • Platform tags updated to manylinux_2_27 and macosx_12_0_*; 32‑bit Windows wheel removed.

Breaking changes (see release notes for migration details):

  • Renamed members require code updates (e.g., options.z_order → options.zorder).
  • Attribute assignments that target non‑existent members raise AttributeError instead of being ignored.
  • Engine errors now raise GroupDocsSignatureException, IncorrectPasswordException, or PasswordRequiredException rather than RuntimeError.
  • The 32‑bit Windows wheel is no longer provided; pip 20.3 or newer is required.

Install:

pip install groupdocs-signature-net==26.10.0

As always, feedback and bug reports are welcome in this category.
