dtSearch full changelog

Fixes and minor enhancements:
dtSearch Desktop indexer now reports image-only PDF files in the index update log. (Metadata in these files is still indexed. This change only affects reporting in the index update log.)
Improved 32-bit indexing performance in low-memory conditions.
Fixed indexing crash in mso20win32client.dll in the latest update to Office 2016 when indexing Outlook messages.

All executables are code signed using SHA-2 in addition to SHA-1 (dual signed). All MSI files are signed using SHA-2 only, because MSI files do not support dual signing. Please see this Microsoft article for more information on SHA-1 deprecation.
Added option in dtSearch Desktop's Edit > Copy File function to automatically shorten excessively long filenames.
Added new C# sample, AjaxWordListBuilder, demonstrating how to use the dtSearch Engine's WordListBuilder object on a web page.

Fixed security issue reported in a third-party component, imgman32.dll, used in the dtimage.exe utility. See http://support.dtsearch.com/faq/dts0235.htm for more information.
Added support for indexing Outlook 2013 and 2010 OST files. Note: Microsoft has not officially documented the OST file format specification, so this support is based on unofficial non-Microsoft information about the OST file format.
Added support for indexing metadata in Adobe Photoshop images
Fixed "~dtpdf.tmp" filenames appeared in tabs in dtSearch Publish
Fixed PDF hit highlighting error in dtSearch Publish on systems with Adobe Reader versions 7-9 and Internet Explorer 10
Added "Images" field at the end of MIME messages listing names of inline image files.
Fixed incorrect handling of filename-only indexing option causing "Unsupported file format" errors
In the API, the flag dtsIndexCreateVersion6 is now ignored, so indexes will always be created in the current index format.
