### Notes

- When you use the `WkoopHtmlExtraction` task or `wkoop_html_processing` Lua function, the embedded web browser (WKOOP) is no longer permitted to navigate away from the source page. If necessary you can allow navigation by setting the new configuration parameter `AllowNavigations=TRUE`, or by setting the named argument `allow_navigations` in the Lua function call.

## 23.2.0

### New Features

- The `WkoopHtmlExtraction` task can use the Mozilla readability library to clip pages. Clipping removes uninteresting parts of a page such as navigation bars and advertisements, to prevent irrelevant information being added to the IDOL index. Automatic clipping was available in previous versions of CFS but the readability library produces better results in some cases. To clip pages using the readability library, set `ClippingMode=READABILITY`. This feature is not available on FIPS-compliant platforms.
- When extracting metadata from a page, the `WkoopHtmlExtraction` task can write the information into structured document fields. Earlier versions of CFS could not be configured to write this information into sub-fields.

### Resolved Issues

- CFS could terminate unexpectedly when `ImportExtractExternal=TRUE` and a file contained multiple URLs to external files.

### Notes

- As a result of the improvements to clipping, you must update any `WkoopHtmlExtraction` tasks that perform clipping. The `Clipped` parameter has been removed and replaced with a new parameter, `ClippingMode`. For more information, please refer to the Connector Framework Server Help.

- As a result of the improvements to metadata extraction, you must update any `WkoopHtmlExtraction` tasks that extract metadata.

  - In earlier versions of CFS, the `MetadataSelector` and `MetadataFieldName` parameters accepted multiple values. With CFS 23.2 these parameters accept a single value and you should use the new parameter `MetadataFieldSections` to specify the names of sections that contain these parameters (one section for each field that you want to create in your IDOL documents).

    The configuration parameter `MetadataSelectorExtractPlainText` has been renamed to `MetadataExtractPlainText`.

    For example:

    CFS 12.13 | CFS 23.2
    --- | ---
        [WkoopHtmlExtractionTask]
        ...
        MetadataSelector0=h1
        MetadataFieldName0=HeadingOne
        MetadataSelectorExtractPlainText=TRUE
        [WkoopHtmlExtractionTask]
        ...
        MetadataFieldSections0=ExtractH1

        [ExtractH1]
        MetadataSelector=h1
        MetadataFieldName=HeadingOne
        MetadataExtractPlainText=TRUE

  - The configuration parameters `ChildMetadataSelector`, `ChildMetadataSelectorExtractPlainText`, `ChildMetadataFieldName`, and `ChildMetadataAttribute` have been removed. You can now extract metadata for child documents using the same parameters that you would use for the main document. Use the new parameter `ChildDocumentMetadataFieldSections` to specify the names of sections that contain settings for metadata extraction from child documents.
