Render Engine 2026.10.1a1 Released

Render Engine 2026.10.1a1 has been released as an alpha release for testing. This versions includes:

• Removing of support for Python 3.10 and adding Python 3.15
• Improved error handling when rendering a Site:
  • Collection.render will aggregate exceptions from all entries it renders and, if there were exceptions, raise an ExceptionGroup.
  • All Exceptions encountered during rendering will be annotated with relevant data to help you understand which entry caused the Exception to be raised.
  • On completion of rendering all entries the Site will, if any Exceptions occurred, output to STDERR the annotations from the accumulated Exceptions and store the complete back traces (including the annotations) to a log file in the Site's output directory.
