Added

    • relevance (default): Sort by relevance to the content
    • random: Randomize the order of visual layouts
  • Add new warning code visual_id_with_random_sort: Warns when using sort_strategy: random with specific visual_id or visual_ids. This combination may not produce the expected randomization since you've already constrained the visual selection.

  • Fix number_of_visuals not being respected when color_mode=both is specified

Improved

  • [Internal] Internal structural updates

v0.8.5 (2025-11-11)​

Added

  • Add warnings field to visual request status responses. This field contains an array of warnings about non-critical issues that occurred during processing, allowing you to understand partial failures where some visuals were generated successfully but others encountered issues.

Available warning codes:

  • missing_visual_ids: Some requested visual layouts could not be generated because the content does not fit the layout. This occurs when specific visual_ids are requested but the content is too long or doesn't fit. Resolution: Try reducing text length, using different visual IDs, or omitting visual_ids to let the system choose appropriate layouts automatically.
  • invalid_style_id: The requested style_id could not be found or applied. The system generated visuals using the default style instead. Resolution: Verify the style_id is correct by checking the available styles.
