- Changing the global locale could cause KeyView to fail to process some file formats.

- When attempting to filter NIST_ITL_Fmt files, KeyView returned KVERR_FormatNotSupported.

- Some child windows were not displayed in the viewing window. For example, this issue meant that mail bodies were not displayed and attachments could not be opened.

- When processing HTML files that specify an ISO-2022 character encoding, KeyView output some entities as unprocessed strings, rather than the correct unicode character.

## 23.2.0

### New in this Release

- KeyView format detection has been extended, with support for 56 additional file formats. By identifying a larger range of formats present in the enterprise, decisions can be made on how to route, filter, or alert on such documents. For the full list, refer to the KeyView Viewing SDK Programming Guide.

- KeyView has been simplified so that it is much easier to map file formats to readers. File formats no longer have an associated "category". The KeyView configuration files such as `formats.ini`, `formats_e.ini`, and `kvsdk.ini` now identify file formats using the same file format numbers that are returned by format detection.

- KeyView can now extract all platform-specific embedded files from `PDF_Fmt` documents.

- KeyView can now process certain OpenOffice Text files that it would previously reject, and it can process image alt text in OpenOffice Text as hidden text.

- KeyView now supports TIFF (`TIFF_Fmt`) files that use WebP compression.

- Handling of Arabic diacritics (tashkil) has been significantly improved when using the pdfsr reader to process PDFs.

- Text ordering has been improved when using the pdfsr reader to process PDFs.

- The FreeType third-party library has been upgraded to version 2.12.1.

### Resolved Issues

- (Security update) The third-party libtiff library has been upgraded to version 4.5.0 to resolve known vulnerabilities, including CVE-2022-2056, CVE-2022-2057, CVE-2022-2058, CVE-2022-3452, CVE-2022-3570, CVE-2022-3597, CVE-2022-3598, CVE-2022-3599, CVE-2022-3626, and CVE-2022-3627.

- KeyView could truncate long sections of text in `PDF_Fmt` documents.

- For some Microsft Excel (XLSX) files with a lot of cells using Rich Data Types, KeyView output the names of those types incorrectly, using a number instead of a type name.

- In Word Processor formats such as Microsoft Word (DOCX), embedded images with text wrapping around them were sometimes rendered above the text, obstructing it. To avoid this, ViewingSDK now places images at the start of paragraphs to ensure that the text is readable, making the output more consistent with HTML Export.

- KeyView could skip some user defined properties in summary information for some OLE-based files like `MS_Project_2007_Fmt`.

- When using the pdfsr reader for text in right-to-left languages, diacritic characters were sometimes not extracted correctly.

- Some PDF files took longer to process in version 12.13.0 of the SDK than in version 12.12.0.

- KeyView could exit unexpectedly when processing some Microsoft Visio (.vsd) files.

- KeyView missed text from some Microsoft Visio (.vsd) files.
