Updates & Enhancements

Bug Fixes

This release includes number of bug fixes that improve the Nitro Pro user experience.

  • Previously, Nitro Pro required Windows Explorer to restart during the product upgrade process. To improve automated deployment of Nitro Pro, Windows Explorer will no longer restart when upgrading from version 12.0 (or later) to subsequent versions of Nitro Pro.
  • An issue caused Nitro Pro to crash when loading the IRS 1040 document. This has now been fixed.
  • Previously, links to places within a document did not function correctly after converting a Word document to PDF. This has now been fixed.
  • When copying pages in Nitro Pro, if a document had an attachment, it was treated like a page attachment and copied. Nitro Pro now only copies attachments which are attached to the page being copied.
  • Previously, Nitro Pro allowed users perform a split operation on signed documents. Nitro Pro now disables the split option for signed documents.

XFA Document Message

Nitro Pro now provides a more user-friendly message when XFA documents, created specifically for Adobe Reader, are opened in Nitro Pro.

Previous Versions


Updates & Enhancements

Bates Numbering

Nitro Pro 12.9 has an improved Bates Numbering feature for large documents. Documents containing thousands of pages can now be processed more reliably, enabling organizations to efficiently index their documents for easier identification and retrieval.

Worksite Improvements

Nitro Pro 12.9 now works better with Worksite 9 Document Management Systems. When opening documents directly from a Worksite file system to edit in Nitro Pro, or when creating new files, Nitro Pro will behave as follows:

  1. When using the Save function, the current version of the file will be overwritten by default. The document will be checked in upon closing.
  2. When using the Save As function, a dialog will be presented with the following options:
    • Overwrite current version
    • Check in as new version
    • Save as a new document


Updates & Enhancements

User Experience Enhancements

Nitro Pro 12.8 includes numerous user experience improvements that make it faster, easier, and more intuitive for users to work with Nitro Pro.

  • A ‘Find’ button has been added to Nitro Pro’s home tab, so users can quickly open the Search Panel to locate words or phrases within PDF files.
  • When saving a document as a PDF from Nitro PDF Creator and Microsoft Office add-ons, Save dialogs now offer a “Favorites” option, enabling users to more quickly save documents to frequently-accessed locations.
  • Nitro Pro users will now be notified when an XFA file has been opened. Nitro does not fully support XFA files, as the format is proprietary to Adobe and is not ISO standard. Therefore, upon opening an XFA file in Nitro Pro, users will be informed that the contents of the document may not be accurately displayed or saved.
  • Nitro Pro has improved font detection, enabling users with a wider variety of custom fonts when converting documents from PDF.

OCR (Optical Character Recognition) Improvements

This release also includes improvements to Nitro Pro's OCR capabilities, which enable users to transform scanned documents into searchable and editable PDF files. The enhancements available in Nitro Pro 12.8 include:

  • Quality improvements that enable more accurate and effective editing of scanned documents

  • On occasion, when converting an MS Office document containing special characters to PDF, Nitro Pro would not correctly display the content. This issue has been resolved and special characters are now displayed accurately when converting documents.

Resolved Issues

  • Nitro Pro has improved a Javascript command, which enables the manipulation of pages in a PDF document that contain annotated elements, such as form fields. These annotation elements will now be displayed accurately upon execution of the command.
  • When opening documents from Google Drive, users can now see the document's file size.
  • Users can now create extra large form fields, measuring up to 130x130in (3302x3302cm).

This specific error would appear only if SharePoint credentials were removed from Windows Credential manager. The issue has been resolved and Nitro Pro works as expected for multiple-requests scenarios.

OmTool deprecation

*This feature has been released in beta and will be improved incrementally with future versions.

  • After closing a SharePoint document, users experience a long delay before they receive a message about checking said document back in, or keeping it checked out. This delay can create confusion about which document the message pertains to.

  • When a document has been certified, the certification cleared, and the same form field re-used for a digital signature, it will result in the document becoming editable.
  • The markup context menu does not appear on a digitally signed document.
    Workaround: Use keyboard shortcuts or contextual Ribbon menu to perform actions on markups.

  • Workaround: Create standard PDF documents or PDF/A documents without tagging.

  • PDFA-1b documents appear without links, bookmarks or PDF view options, when generated using Nitro Pro printer driver.
  • Workaround: Create standard PDF documents with Nitro Pro printer driver, navigate to Convert tab in Nitro Pro and select Convert to PDF/A- 1b.
