Nitro PDF Pro for Windows now supports multiple languages from a single installation package, which simplifies the installation deployment experience and allows users to easily change languages post-installation without re-installing Nitro PDF Pro in the alternate language.

Key benefits:

• Deploy localized application with a single installer. To simplify the deployment experience, administrators can now deploy Nitro PDF Pro with only one installer per platform. The deployed application language can be defined during the installation process or the choice can be delegated to an end user. 
• Users choose the language they want on first run. By default, Nitro PDF Pro installer delegates the choice of the application language to an end-user and the user is prompted to select a preferred language when they first launch Nitro PDF Pro. If users are manually installing Nitro PDF Pro rather than having it deployed for them, they can select their language as the first step of installation. 
• Change the interface language anytime. Any user can change the language of Nitro PDF Pro any time after the product is installed. To do this, the user selects their desired language in the application preferences. 

Improved Conversion to Excel when Leading and Trailing Zeros are Present
New support for custom formats of numbers when converting from PDF to Excel allows for leading and trailing zeros. These custom formats are automatically used when leading or trailing zeros are found.

Stability Improvements

• Nitro PDF Pro is now more resilient to working with documents stored on a network drive and there is a poor network connection. 
• When malformed content is found within a PDF, Nitro PDF Pro has improved the handling of content so it is displayed if possible. 
• Nitro PDF Pro is now more resilient to working with documents stored on a network drive and there is a poor network connection. 
• Redaction codes are saved to a document faster. 
• Improved stability when deleting annotation comments. 

Enhanced “Undo” capabilities

• Editing annotations 
• Handling empty lines

Saving text from the Text Type tool
Text entered in a document via the “Type Text” tool is now saved when clicking on another location of the document instead of only when explicitly clicking “Finish.”

A security vulnerability previously reported has been addressed in this release. Please visit our Security Updates page for more information.

New SharePoint Online Extension

With the new SharePoint Online Extension, documents can be opened in Nitro directly from SharePoint Online. The SharePoint Online Extension eliminates the need for users to download, edit and then manually upload their documents back to SharePoint. Instead, users can open the PDF from SharePoint, make changes, and simply save the document.

Improved SharePoint Connector

From the alternate direction as the SharePoint Online Extension that gives a superior experience in SharePoint to interact with Nitro PDF Pro, the SharePoint Connector allows users to connect to SharePoint (Online, 2019 or 2016) from within Nitro PDF Pro. With this release, these benefits are available:

• Complete document lifecycle: Open, edit, save a SharePoint document, as well as upload a new document to the SharePoint server - all this is available from within Nitro Pro. 
• Granular access: Add connector to the SharePoint site or library to works with the documents from the favorite location. 
• Availability and versioning control: Control document availability with automatic check out, and Manage document versions with automatic check in. 
• Seamless Integration: Nitro Pro seamlessly integrates with SharePoint. 

Create PDFs as a New Version of an MS Word Document

Users can convert an iManage MS Word document to PDF and save it above the original MS Word document as a new version.

NEW: OCR Language Support for Ukrainian

Nitro PDF Pro is happy to introduce optical character recognition (OCR) for PDF documents written in Ukrainian. The package can be requested through the Nitro Support team.

Improved JavaScript Performance

Using JavaScript in Nitro PDF Pro is becoming easier and more reliable. This new version provides better JS calculation performance which increases the amount of static PDF-forms that can be filled in Nitro Pro.

Better Support for PDF with Embedded TIFF Images

With each version of Nitro PDF Pro, the quality of document rendering improves. Previously, some PDFs containing TIFF images were rendered without the TIFF image displayed or the editing experience was not sufficient. Now, Nitro PDF Pro decodes and renders the TIFF images correctly and the editing experience has been enhanced.

Improved Nitro PDF Pro Performance on a Network Drive

Nitro PDF Pro is now more robust and responsive when working with a document on a network drive.

Because it can be challenging to work with a network drive document and a slow network, Nitro PDF Pro now ensures that progress of any document operation is reflected properly within the user interface while the product remains responsive.

Improved Performance for PDFs with a Large Number of Form Fields

Nitro PDF Pro has improved performance when working with many form fields. Documents with many form fields are now significantly faster when text is being input to give users a superior experience.

Extended Support for Next-Generation Cryptography Features

Nitro PDF Pro has extended support for applying digital signatures validated by CA 5 certificates. This support for next-generation cryptographic features allows more modern certificate types to be displayed and used for document signing and certifying.

Enhanced Manageability of Security Profiles in Nitro PDF Pro

Working with Security Profiles is more predictable and robust. Each existing profile now can be amended, and the obsolete or invalid profiles can be removed.

Usability Enhancements

The undo/redo behavior within Nitro PDF Pro has been enhanced. Interactions with text editing, updating forms, and managing bookmarks, Whiteout/Redaction and Shape and Measurement property manipulation have all been improved with increased usability.

Improved Algorithm for Link Detection

Nitro PDF Pro features an improved algorithm for link detection. The algorithm was adjusted to reduce the chance of non-related text being treated as a part of the link. Now the detection of the hyperlink in PDF, especially email links, is more accurate.

Increased Support for English Builds of Nitro in non-English Windows

Localized builds of Nitro PDF Pro now have no impact on the native Windows Explorer context menu content.

Improved Ability to Move Objects Between Pages

The user experience when editing a PDF document is more fluent. Now, it is easier to move objects between pages to achieve a predictable result.

Expanded Support for Proxy Settings

Nitro PDF Pro now has increased robustness within a proxy environment. This facilitates easier integrations with third-party products and other Nitro systems.

The latest version of Nitro PDF Pro extends support to the $ character in PDF URLs.

As a result, a user can also open a URL with the embedded $ symbol, from within a Nitro PDF Pro PDF document.

In this version, Nitro PDF Pro improves the reliability of the Compare tool.

Previously, the Compare tool was not detecting some document changes. This enhancement reduces the amount of false positive results the system produces, when in fact no changes were detected.

This version contains an enhancement around conversions from PDF to Microsoft Excel documents.

Previously, converting some documents resulted in numerical data presented as text, which made it difficult to apply formulas to cells.

Documents affected the most were those with formatting that included numbers with a coma separating groups of thousands. In the new version, Nitro PDF Pro converts numbers with improved accuracy and applies the correct data type to numerical cells.

This release contains an improved user experience when navigating between documents in Nitro PDF Pro.

A user may now navigate back and forth between document views, and perform functions such as a changing zoom, moving between pages and bookmarks etc. This provides for a more efficient user experience.

Previously, users have may experienced issues with documents annotated using Nitro PDF Pro. The issue occurred when the annotation was visible only by Nitro PDF Pro but rejected by other PDF editors.

The new version of Nitro PDF Pro fixes problematic documents and restores visibility of annotations.

It is recommended to resave previously problematic documents using the latest version of Nitro Pro to ensure visibility of annotations in all PDF applications.

Nitro PDF Pro extends the range of supported digitally signed documents.

This version includes support for DocuSign signed documents, which is now recognized and validated accordingly.

Previously, Nitro PDF Pro did not support submitting a PDF form that contained mandatory digital signatures fields.

Such fields had to be excluded or marked as optional. A new version of Nitro Pro supports recognizes the mandatory digital signature fields and allows the user to submit a PDF form with filled data.

Previously, if a user attempted to apply a timestamp from a server and the operation failed, the timestamp from the user’s local computer clock was applied. This was done without any notification to the user that the local computer timestamp was used instead of the server timestamp.

To reduce uncertainty about digital signature validity, Nitro Pro improves messaging when applying a digital signature to the document.

Now, if the operation fails when attempting to apply the timestamp from the remote server, the user sees a message that the local timestamp was applied to the signature instead of the remote server timestamp.

With the latest version of Nitro PDF Pro, a user can be confident that deleting a page, and any bookmarks related to that page, have also been deleted.

This prevents exposing sensitive information that could have been included in any bookmarks.

On a previous version of Nitro Pro, some users many have experienced an error message when opening PDFs, especially those generated by the third party tools.

The latest release has improved this experience, since Nitro PDF Pro has improved its reliability in this area and error messaging has been removed.

Nitro Pro makes the access point to SharePoint more flexible.

In many cases, an organizational SharePoint communication site was at a top level. Meaning, Nitro Pro only connected to that point, not specific department pages. Some organizations do not have a top level of SharePoint, making SharePoint inaccessible by Nitro Pro. This was not an ideal experience.

To solve this problem, the latest version of Nitro Pro allows a power user to predefine the path to the SharePoint site. This also guarantees that users will access a site to which they have permission. This also saves users from searching for the "right" site among all the sites available on SharePoint server sites.

The latest contains an improvement around the Nitro Pro Office add-in for 32-bit Office users on the 64-bit operation system.

Previously users with the 64-bit environment might experience difficulties with enabling the Nitro Pro Office add-in. The new version of Nitro Pro not only resolves this issue, but includes a more robust Office add-in.

When using Search and Copy-Paste functionality in documents with embedded fonts, those functions now perform in a more reliable fashion.

In the latest release, Nitro Pro respects the list of time stamp servers added into Preferences. When applying a digital signature to a document, Nitro Pro defaults to the listed server to request the time stamp, instead of the local operating system.

Using the server time stamp rather than the local operating system has proved to be a trusted form of reference. It also ensures long-term validation and confidence around the signature and when it was actually applied.

In this release, Nitro Pro prevents users from applying signatures with expired or not yet valid certificates. This enhancement improves digital signature reliability.

When applying redaction now, by default, Nitro Pro performs better document inspection on hidden information and prevents hidden data from leaking.

This release contains several enhancements related to iManage workflow robustness.

Previously, users might experience difficulties checking in a document to the server with a custom name or when working with a document with Azure Information Protection.

This release contains improved stability around auto-recovery functionality, even when setting have been changed in preferences.

This release contains an enhancement around Nitro Pro stability when working with complex documents rich in bookmarks, layers and grouped objects.

Any documents stored on SharePoint sites and libraries and protected by Active Directory Rights Management System (AD RMS), now maintain the same ownership and sharing properties. This is important, as it preserves the availability of a document and those original settings, even if the document was modified.

With regards to Microsoft Outlook, this release improved the user experience of digitally signing PDF documents opened as an email attachment. This is applicable to versions 13.44 of Nitro or newer.

This release improved the stability of PDF documents that contain a digital signature. Now, whenever moving through the process and a digital signature is included, the entire document will retain its integrity without an issue.

In some cases, a user of Nitro Pro might have experienced slowness or hanging when working with PDF document that referenced external objects.

In this release, Nitro Pro optimizes the amount of consumed memory when working with such documents. This prevents disruptions in the users workflow and makes the application more reliable.

In some cases, Nitro Pro became unresponsive when the user applied redaction to a large document. With the latest release, Nitro Pro is more interactive when redaction occurs, providing the user with a frequent update on progress.

When applying redaction now, by default, Nitro Pro performs better document inspection on hidden information and prevents hidden data from leaking.

This release contains enhanced security when extracting pages from a PDF document with bookmarks.

This means the final document contains only the bookmarks that belong to the extracted pages. As a result, Nitro Pro provides accuracy in data matching between the bookmarks and the document content. This also prevents the original document data from leaking into the final document.

This release contained two security enhancements that resolved known vulnerabilities. For more information, please visit Nitro’s Security Updates website page.

In this version, Nitro Pro performs better compression of the document by removing unused default object references and reducing document size.

Nitro Pro both adapts and supports the latest updates of the iManage API. Recently, users could experience trouble opening iManage documents in Nitro Pro due to changes in the iManage API.

This release of Nitro Pro is compatible with changes to iManage and allows the user to work with iManage documents in normal mode.

NOTE:
It is highly recommended iManage users update Nitro Pro to version 13.50, especially if their iManage server was updated to v10.4+ or they are using global iManage Cloud.

In this release, signing an iManage document becomes more reliable and predictable.

Previously, a signed iManage document might become checked in while still open in Nitro Pro. This could put a document at risk of possible external modification and loss of data.

In the new version, Nitro Pro behavior is more consistent with other workflows: the iManage document remains checked out by the user after signing until the user closes the document in Nitro Pro.

Important Note for iManage UsersThis release requires iManage users to have iManage Work Desktop for Windows (also known as iManage Agent) updated to version 10.5 or newer.Before updating iManage, please ensure that all documents opened on the same machine are closed and checked in, in order to prevent documents from becoming read-only.

Nitro Pro has been upgraded to use Microsoft .NET Framework version 4.6. This change means Nitro Pro will no longer rely on Microsoft .NET version 3.5 when integrating with Microsoft 365 Office add-ons.

This release improved the performance and stability of Nitro Pro when a user creates multiple custom stamps simultaneously.

The UI has been cleaned up when locally saving signed document opened via the SharePoint IE plugin.

This release of Nitro Pro now displays a single dialog box when signing a document opened from a Document Management System (DMS).

Nitro Pro now remembers and will default to the "Always Use Last Locations in Open and Save as Dialog Boxes" when this has been enabled as a choice within Nitro Pro preferences.

Nitro Pro Performance and Reliability Enhancements

Multiple Nitro Pro enhancements were done to ensure product reliability and stability:

• Printing – Stabilized Nitro Pro when selecting to print a document, especially when the printer was deleted or unavailable  
• Copy/Pasting Large Number of Images - Improved performance when copy/pasting large number of images in the PDF document 
• Bookmarks – Enhanced stability around creating and manipulating bookmarks  
• Page Extractions – Archived more reliable and predictable results of page extractions 
• Deleting Document Attachments – Stabilized Nitro Pro when deleting attachments  
• Stamps Manager – Enhanced reliability of stamps manager  

Security has been improved when redacting on a document with hidden content. Now Nitro Pro applies stricter rules when detecting hidden text, such as a text with the same color as background and removes it accordingly to prevent data leak.

In some cases, when applying redaction to pages with recently changed properties, the text on the page was corrupted.

In the latest version of Nitro Pro, the redaction results are more predictable and do not impact the text outside of the redacted area.

A number of security vulnerabilities previously reported have been addressed in this release. Please visit our Security Updates page for more information.

The latest Nitro Pro release delivers a reliable experience when using copy and paste functionality, particularly while editing images or text on a PDF.

In this enhancement, Nitro Pro preserves the accuracy of document formatting when applying redaction to rotated pages.

In cases where similar text and/or characters are grouped close together, text rendering has been greatly improved. This enhancement results in a better reading and editing experience.

The quality of document rendering with old image formats, such as CCITTFAX, was improved and extended to support. In the latest version of Nitro Pro, this enhancement increases the range of the document that a user can work with.

When redacting items from a document, users can now also remove additional content that may contain sensitive data. This includes items such as bookmarks, metadata, comments and markups, document structure etc.

This is a significant improvement in Nitro Pro security, as users can further prevent data leaks from any redacted document.

• This latest enhancement ensures the integrity of images and graphs, so they remain crisp and clear when converted to PDF. In some previous cases, the converted images displayed blurry and were hard to read.
• IME popup windows (Windows ability to recognize non-Latin characters) will show up in their correct position when the operating system language is set to Chinese (traditional) or Japanese.

• Nitro Pro now includes only the relevant bookmarks in an extracted part of the document. This prevents data leaks from the original document.

• In this version of Nitro Pro, a user can work with SharePoint Online documents from Windows Explorer the same way they used to work with local documents.

Improvements were made to the format of text rendering. When editing, Nitro Pro now renders text as expected.

Improvements were made to stabilize how Nitro handles file size. This ensures there is no increase when changes are made to a document.

Improved messaging for Whiteout and Redaction prompts enable users to choose the best method for their specific needs.

When Metadata is removed in Nitro Pro by the Eraser button, a new enhancement ensures all metadata is removed.

Improved stability and reliability when editing PDF documents:

• When using either the Australian Tax forms or the measuring tools, Stability improvements were made to reduce the likelihood of crashes
• The Type Text tool has been improved to ensure a better user experience

To access Google Drive documents in Nitro Pro, it is recommended to use the Google Drive desktop application to sync documents with Windows Explorer

To reflect changes and improvements to Google’s security policy, a native connector to Google Drive in Nitro Pro has been deprecated.

• Performance has been improved for users who are using a limited Virtual Private Network (VPN), have a slow internet connection, and work with remote storage.
• The Nitro Pro Chromium Embedded Framework (CEF) integration has been upgraded to version 88.2.8.
• Users now have the option to disable the embedded font warning message. It is shown when Nitro Pro must convert an embedded font to a System font.
