* **Expanded Office and OpenDocument file support**: The Gemini API now
accepts PowerPoint 97-2003 (PPT), OpenDocument Presentation (ODP), and
OpenDocument Spreadsheet (ODS) files as input, and adds page-image
processing for Word 97-2003 (DOC) files. DOC, PPT, and ODP files are
rendered as page images. For ODS files, the model receives the data and
formulas from the first sheet.
Processing for DOCX, DOTX, ODT, PPTX, XLSX, and XLS files is unchanged. See
[Office and OpenDocument files](/docs/document-processing#office-documents)
for how each format is processed.

* **More file types and file URIs in function responses**: Tools can now
return Office and OpenDocument files, audio, and video to the model.

* **GenerateContent API**: Function response parts now accept audio,
video, and Office and OpenDocument files, in addition to images, PDFs,
and plain text. They also accept `fileData`, so tools can return a
Files API URI instead of inline bytes. `displayName` is now available
on both `inlineData` and `fileData`, and video parts accept
`mediaProcessing` (`STATIC` or `AGENTIC`).
* **Interactions API**: `function_result` steps now accept `document`,
`audio`, and `video` content blocks, in addition to `text` and `image`,
by inline `data` or `uri`. Video blocks are available in `v1beta` and
`v1alpha` and accept `processing`.
