v1.17.0

UniOffice v1.17.0 includes multiple new features and a few significant improvements. ActiveX form field support has been added, line breaks can now be added easily, and Nodes can be used to easily search and replace text by pattern, enabling powerful redaction. PDF conversion for docx files also keeps being improved.

New features:

• Paragraph border support added. Enables an easy way to add line-breaks, similar to in MS Word, where one can type in "~~~", "***", "---" followed by newline/Enter to insert a horizontal rule. [UO-117]
  Example: https://github.com/unidoc/unioffice-examples/tree/master/document/paragraph-borders/main.go
  shows a few different cases for paragraph borders including line breaks.

• Support for ActiveX form fields. Support added for reading and editing MS Word ActiveX fields. [UO-65]
  Example: https://github.com/unidoc/unioffice-examples/tree/master/document/form-activex/main.go
  demonstrates how get and change values from ActiveX forms.

• Text redaction with Nodes to find and replace text. Adds easy to use functions for search and replace of text supporting text and regular expressions. [UO-108]
  Example: https://github.com/unidoc/unioffice-examples/tree/master/document/node-find-and-replace/main.go
  shows how to use nodes to easily replace text in a docx file.

Improvements:

We added more test cases and fixed cases where the PDF conversion was faulty.

• Account for style inheritance in PDF conversion. [UO-114]

• docx to PDF crashes: nil error [UO-119]

• PDF conversion for fields improvements. Improve conversion of fields, and added an option to process fields that is off by default.
  If enabled, it is similar to how LibreOffice enables displaying hidden fields. [UO-109]
  Examples: https://github.com/unidoc/unioffice-examples/tree/master/document/convert_to_pdf/main.go
  https://github.com/unidoc/unioffice-examples/tree/master/document/convert_to_pdf_options/main.go
  Can see the difference in output when processing the merge_fields conversion case with and without the
  ProcessFields option, which causes fields to be processed and displayed if hidden (LibreOffice feature).
  The default behavior is consistent with MS Word.

• Idempotency style when style already exist. The document AddStyle function now returns a style if the styleID already exist. [UO-116]

NOTE: There is technically one breaking change in this release that we believe should not affect any users.
The common/tempstorage tempstorage.File interface now has added io.ReaderAt requirement. This was needed
to add the ActiveX support which is based on binary file processing. The provided implementations
memstore and diskstore have been updated. We do not believe that there is any other potential
use of the interface, so the change was accepted in this minor version.
