  - |
    The `AzureOCRDocumentConverter` no longer produces `Document` objects with the deprecated `dataframe` field.

    **Am I affected?**
    - If your workflow relies on the `dataframe` field in `Document` objects generated by `AzureOCRDocumentConverter`, you are affected.
    - If you saw a `DeprecationWarning` in Haystack 2.10 when initializing a `Document` with a `dataframe`, this change will now remove that field entirely.

    **How to handle the change:**
    - Instead of storing detected tables as a `dataframe`, `AzureOCRDocumentConverter` now represents tables as CSV-formatted text in the `content` field of the `Document`.
    - Update your processing logic to handle CSV-formatted tables instead of a `dataframe`. If needed, you can convert the CSV text back into a `dataframe` using `pandas.read_csv()`.
