Dear GroupDocs customers,
We are pleased to announce the release of GroupDocs.Comparison for .NET 26.8. This release focuses on the pdf enhansments: the comparer now builds its result fully in memory, the detected change list is available for Side-by-Side PDF results, and a concurrency issue that caused crashes during parallel PDF comparison has been fixed.
Key Features & Improvements
-
In-memory stream processing in PDF Side-by-Side comparison (COMPARISONNET-4828)
-
Change list is now available for Side-by-Side PDF results (COMPARISONNET-4728): Previously, the list of detected changes was not returned when the result was generated in Side-by-Side PDF mode. Starting from this release,
Comparereturns the full change collection in this mode as well, so the changes can be inspected, counted, or exported alongside the produced document. -
Fix crashes during concurrent PDF comparison (COMPARISONNET-4830): Running several PDF comparisons in parallel could lead to unexpected exceptions and process crashes caused by shared state inside the PDF processing pipeline. The affected components are now thread-safe, so multiple PDF comparisons can be executed simultaneously — for example, from a web service handling concurrent requests or from parallel batch processing.
