The NuGet package is now split into a lightweight router plus per-target-framework runtime packages, adding first-class .NET 6 and .NET 8 builds. The engine upgrade also required a set of fixes: presentation (PPTX) image annotations, Visio (Diagram) area/redaction fill and slide-preview generation, a crash when cleaning Visio documents that contain hyperlinks, Diagram document-info text extraction, a NotImplementedException when saving annotated image files, and a NullReferenceException when reading annotations from HTML documents with footnotes or endnotes.
