PrizmDoc v14.10Sep 25, 2026
Features
PrizmDoc Server Windows now supports using Apryse Server SDK to render Microsoft Office formats with improved fidelity by setting fidelity.msOfficeDocumentsRenderer to apryse.
PrizmDoc Server Docker now supports converting and viewing HWP and HWPX documents.
Improvements:
If a PrizmDoc Docker container is started with a user that does not have a writable home directory, it will automatically create one in the /tmp folder. This allows components like fontconfig to write cache data in their default locations.
When using the Apryse Server SDK renderer, Excel 95 and PowerPoint 95 documents are now processed using LibreOffice.
Fixes
Addressed an issue where the Apryse watermark could start to appear on certain document types when using the Apryse Server SDK renderer.
Addressed an issue where the Apryse Server SDK renderer was not restarted after becoming unhealthy.
When using the Apryse Server SDK renderer, Excel documents that exceed the supported cell-count limit now fail fast instead of waiting for request timeouts.
Fixed an issue where the Format Detection Service could not properly detect some specific formats.
Addressed an issue with digital signing of Windows installers.
Addressed an issue with the Viewer Control wildcard search not matching words that have trailing punctuation.
Addressed an issue with several corrupted fonts and images included for use in text signatures in prizmdoc-viewer.
Addressed an issue where redactions could fail for PDFs with circular form resource references when using the sharedImages parameter.
Security Updates
Addressed potential vulnerabilities in the nginx component by upgrading to the newer nginx v1.30.3.
Addressed potential security vulnerabilities by upgrading Lodash to the latest version.
Addressed potential vulnerabilities in components of PrizmDoc Email Processing Service and PDF Processing Service by updating those to the most recent versions.
Addressed a security vulnerability in prizmdoc-viewer by updating development dependencies to the latest versions.
Updated MongoDB Server included in our product to version 8.3.3, taking advantage of recent security fixes.
Updated PrizmDoc Server Docker images to include Microsoft .NET 10 Runtime and added support for .NET 10 Runtime on Windows deployments. This update helps ensure continued access to Microsoft's latest security updates as .NET 8 approaches end of support.
Addressed a potential security vulnerability in the ViewerControl.
PrizmDoc v14.9Jul 11, 2026
Features
PrizmDoc Server Docker now supports using Apryse Server SDK to render Microsoft Office formats with improved fidelity by setting 'fidelity.msOfficeDocumentsRenderer' to 'apryse'. The 'accusoft/prizmdoc-viewer-eval USE_APRYSE_SDK' environment variable has been replaced with 'MS_OFFICE_DOCUMENTS_RENDERER=apryse'.
NOTE: This support is currently for Docker. Windows support will come in a future release.
Inverse Redaction PrizmDoc now allows for creating inverse redactions, a selective redaction that defines content to preserve and redacts the rest of the page. This new mark is fully supported in the viewer and in the Markup Burner API.
Added a new Viewer Control PageRedaction mark type and an InverseRedaction mouse tool. The InverseRedaction tool can be used to create a PageRedaction with a visible region, or to add additional visible regions to an existing PageRedaction.
Added a new PageRedaction mark type to the PrizmDoc Viewer Markup Burner API. This mark performs selective redaction by preserving specified regions and redacting the rest of the page.
The PrizmDoc Server Windows Installer now detects and blocks upgrades when the currently installed version contains one or more components that are newer than those included in the version being installed. The installer halts before modifying the system to prevent an unusable installation.
Introduced a new 'fileTypes.email.renderAllRecipientHeaders' parameter in Central Configuration to control whether repeated 'To', 'CC', or 'BCC' recipient headers in 'EML' email documents are merged and rendered as a single header. By default, only the first occurrence of each recipient header is rendered.
Fixes
Fixed an issue in ViewerControl where the EditMarks mouse tool could not select marks via drag selection.
Fixed an issue in the PrizmDoc Viewer where rectangle zoom could result in an incorrect scroll position when viewing large documents.
Security Updates:
Addressed potential security vulnerabilities by upgrading Consul to the latest version.
Addressed potential security vulnerabilities by upgrading AWS SDK to the latest version.
PrizmDoc v14.8Apr 4, 2026
Features
Introduced a new parameter in Central Configuration to control transfer timeouts when downloading external content in HTML documents and HTML bodies of email documents.
Setting this parameter to a smaller value will allow faster rendering of HTML when external content is not available.
Fixes
Fixed an issue where the load balancer might not correctly distribute requests after a server was removed from the configuration and later re-added.
Fixed an issue where creating a viewing session from an existing PDF-only viewing package through the PAS /ViewingSession API using source.type: "upload" caused failures in subsequent API calls that use that viewing session.
Addressed an issue with PrizmDoc HTML Conversion Service going unhealthy after in-place Windows upgrade from the latest available version 13.28 to version 14.
Security Updates:
Addressed a potential vulnerability in a component of PrizmDoc Application Services (PAS) by updating it to the most recent version.
Addressed a potential vulnerability in a component of prizmdoc-core by updating it to the most recent version.
Addressed a potential vulnerability in a component of the Viewing Service by updating it to the most recent version.
Addressed a potential vulnerability in a component of the Workfile Service by updating it to the most recent version.
