OPSWAT AI Content Inspector release notes

V 2.2.0

Release date: 8/10/2026

Release type: MAJOR

AI Content Inspector 2.2.0 introduces support for additional email file formats, expands forensic analysis capabilities for embedded images, and includes improvements to provenance validation, image processing, and overall engine stability.

New Features

• Added support for E-mail Message (.eml) files

• Added support for Microsoft Outlook Message (.msg) files

• Added metadata forensic analysis for images embedded within PDF documents, enabling the engine to inspect image-level metadata and forensic signals extracted from PDF content

Changes and Improvements

• Strengthened C2PA provenance validation and handling to improve reliability when analyzing Content Credentials and provenance information

• Improved image input normalization to provide more consistent preprocessing across supported image formats and improve downstream analysis reliability

Bug Fixes

• Fixed a dependency issue affecting the C2PA library

• Fixed processing issues affecting EPS files

• Fixed an issue where grayscale and bilevel EPS images could fail during processing

• Resolved a stability issue where processing FPX files could cause the scan to terminate unexpectedly. FPX is no longer supported by AI Content Inspector

• Fixed an issue affecting LA-mode images, including certain .cur cursor files, which could fail with a "not enough image data" error

V 2.1.1

Release date: 8/10/2026

Release type: MINOR

• Detect AI Model Family from Image Metadata

• New OriginLens image detector

• Improved speed for image scanning (fast & forensic mode)

• Resolved issues affecting text scanning functionality

• Enhanced support for offline and packaged deployments

V 2.0.0

Release date: 5/21/2026

Release type: MAJOR

• Added 10 new image detectors to analyze AI-generated footprints in visual content

• Introduced 9 new text detectors to identify AI-generated footprint signals in textual content

• Enhanced results page with deeper insights, providing more detailed outputs from individual detectors, including images and analysis breakdowns

• Introduced a new Uncertain Hits Threshold setting to improve control over uncertain detection results

• Added support for PDF file type including both AI text detection and AI image detection workflows

• Introduced fraud detection support for the following content types:

  • Invoice fraud
