Conversion Service Release Notes

Added

• Convert documents into structured XML data using the Convert to XML workflow. For more details, review Convert to XML workflow documentation.
• With this release, Licensing Gateway Service supports forward proxy configuration. For more details, review Configure a forward proxy.

Changed

• Renamed workflows in the Conversion Service Configurator to better describe their purpose. The following workflows have been renamed:
  • Previous name | New name
  • Conversion | Convert to PDF
  • Dossier | Create Dossier PDF
  • Archive PDF/A-1 | Archive as PDF/A-1
  • Archive PDF/A-2 | Archive as PDF/A-2
  • Archive PDF/A-3 | Archive as PDF/A-3
  • Invoice | Prepare Invoice PDF
  • Sign | Sign PDF
  • Archive TIFF | Archive as TIFF
  • Extraction | Extract XML from PDF
• Removed the Accessibility workflow from the Conversion Service.

Fixed

• Before this update, when converting Word documents containing field codes (such as { FILENAME }), the field values displayed Conversion Service temporary folder paths instead of the original values. With this update, field codes retain their original values in the converted documents.

Changed

• During Word-to-PDF conversion, Word opens documents without updating external links (UpdateLinksAtOpen = false). Previously, documents with external image or data references combined with <w:updateFields w:val=“true”/> triggered a security dialog that blocked COM automation, causing Word to stop responding and time out. The underlying issue was fixed, and as a result, documents with linked external content, such as images on network shares, use the cached version stored in the document rather than refreshing links during conversion.

Added

• Added support for converting S/MIME signed emails (.p7m). Before this change, signed emails failed to convert. As of this release, the Conversion Service unwraps the signature and converts the email content. Signature validity isn’t verified. Encrypted signed emails aren’t supported.
• Added a progress indicator (spinner) in the Configurator during service start, stop, and restart operations. The spinner replaces the service control buttons while an operation runs, providing visual feedback and preventing accidental duplicate operations.

Changed

• Warning events in the Conversion Service Configurator now use subcategories within their top-level categories, such as Document Integrity, External Resources, Visual Fidelity, and Removed Features under the General category. Each warning also displays which input file types it applies to (PDF, HTML/email, Image, and Office). This makes it easier to find and understand relevant warnings when configuring workflow profiles.
• Updated Conversion Service license agreement.

Fixed

• Fixed trailing
  tags and whitespace-only nodes in email HTML bodies causing extra blank pages in PDF output.
• Fixed attachment names overlapping in email headers by preserving valid XML whitespace characters (tabs, newlines) when sanitizing HTML.

Added

• Added OpenTelemetry (OTLP) support for exporting traces, logs, and metrics to observability backends such as Grafana, Datadog, Seq, and Jaeger. For more information, review OpenTelemetry (OTLP) documentation.
• Added an offline activation wizard in the Conversion Service Configurator for managing license keys in full offline mode. For more details, review Full offline mode activation section.
• Added license expiration date display in the Configurator.

Changed

• Custom XMP metadata handling preserves existing document metadata (Author, Title, Subject, Keywords) when setting individual XMP fields, such as xmp:CreatorTool.
• License state validation now detects licenses that have been removed from the online Licensing Gateway Service (LGS). As a result, licenses that were previously hard to remove are now properly cleared from the Conversion Service Configurator.
• Removed License not added pop-up on Configurator startup.
• Removed .NET Framework 4.7 requirement from the installer.

Fixed

• Fixed Configurator memory leak caused by event handlers.
• Fixed license validation incorrectly marking licenses as invalid when using a remote LGS.
• Fixed Archive workflows failing with ArgumentException when resizing PDF forms containing AcroForm fields.

Added

• As of this release, you can extract XML data from documents processed by the Pdftools OCR Service using the Extraction workflow. This workflow uses the Result Mode option in the Configurator OCR Settings to output the structured XML from OCR results.
• Added mail connectors in Docker deployments.
• You can now import Connections.xml and configure mail secrets in Docker.
• Mail connectors can now process email body and attachments separately.
• Added license-based access control for the Conversion Service Configurator. Most of the tabs are now hidden when no valid license key is set and are displayed when you activate a valid license key.
• Added quick file removal options in the Conversion Service Client user interface, including a right-click context menu with Remove selected and a trash icon when you hold the pointer over items in the input list for deletion.
• Improved the Processing Steps user interface in workflows. Optional processing steps now display clickable links that scroll to the relevant configuration section with checkmarks or warning icons indicating whether settings are complete.
• Added a splash screen for the Conversion Service Configurator.

Changed

• Conversion Service Docker image size reduced by ~4% (1.87 GB to 1.8 GB).
• Configuration Updater Docker image size reduced by ~45% (238.75 MB to 131.75 MB).
• Office conversion is disabled by default. You can configure an Office user from the pre-processing step in workflow setup or in the Conversion Service tab. Once configured, a prompt asks whether to enable Office conversion for all workflow profiles or leave it disabled for manual configuration per profile.

Fixed

• Improved OCR error logging with more descriptive messages when OCR Service errors occur.
• Updated vulnerable packages for improved security.
• Optimized the Conversion Service Configurator graphical interface performance.

Added

• As of this release, your page credits consumption under the License tab in the Conversion Service Configurator.
• Added Gmail connectors for integration with Gmail accounts. The new connectors include:
  • Watched Mailbox (Gmail): Input connectors that convert emails from Gmail mailboxes.
  • Output Mailbox (Gmail): Output connectors that copy processed files to Gmail mailboxes.
  • Send Email (Gmail): Email sending connectors that send notifications and results through Gmail SMTP server.
    Each Gmail connector type supports two authentication methods:
  • App Passwords: Authenticate using Gmail App Passwords, which requires 2-step verification.
  • OAuth 2.0: Authenticate using your organization’s OAuth credentials from Google Cloud Console. Provides organization-level control over email access, independent credential management, and dedicated rate limits that are separate from those of other users.
    All of these connectors include IMAP/SMTP settings optimized for Gmail. For more information, review Gmail connectors documentation.
• You can now extract property values generated through the workflow components and use them where available with the placeholder syntax.
• The Dossier workflow now lets you configure PDF annotations that can be positioned on PDF dossier pages and table of contents pages.

Fixed

• Fixed an issue with widget annotation text not present in the output after PDF/A conversion.
• The MSG files attached to emails have properly rendered characters.
• The license agreement has been updated to the new terms and conditions.

Added

• Added a new Output File Settings section in the Dossier workflow configuration, introducing configurable attributes for invalid filename characters and maximum filename length.
• As of this release, you can now convert JPEG File Interchange Format (JFIF) images to PDF. The JFIF conversion to PDF is included in the following workflow profiles:
  • Conversion
  • Archive PDF/A-2
  • Archive PDF/A-3
  • Archive PDF/A-1
  • Archive TIFF
• As of this release, you can linearize PDF documents during the conversion process. This will create a PDF document that is optimized for fast web viewing. Linearization is available in the following workflow profiles:
  • Conversion
  • Archive PDF/A-2
  • Archive PDF/A-3
  • Archive PDF/A-1

Fixed

• Fixed an issue with a multi-level table of contents creation in the Dossier workflow that failed under certain conditions. For more information, review Dossier documentation.
