Upgrade product with the latest versions of internal libraries

The release bundles the newest builds of GroupDocs internal components. The updated libraries bring:

  • Better compatibility across the GroupDocs ecosystem (Viewer, Compare, Converter, etc.).
  • Enhanced document processing capabilities and broader format support.
  • Cross‑product functionality improvements that translate into smoother annotation workflows.

Update external third‑party dependencies to latest versions

All external dependencies—.NET runtime libraries, image‑processing modules, and document‑parsing utilities—have been refreshed to their current stable releases. Benefits include:

  • Performance gains from upstream optimizations.
  • Bug fixes and security patches supplied by third‑party maintainers.
  • Improved compatibility with modern development environments and CI pipelines.

Improve product stability for document processing

Stability has been a primary focus for this version. The enhancements cover:

  • Robust error handling to prevent crashes on malformed or edge‑case documents.
  • Optimized memory management and more aggressive resource cleanup, reducing the memory footprint during long‑running annotation sessions.
  • Consistent performance when processing multiple documents sequentially.

These changes collectively make annotation operations more reliable, especially in high‑throughput or server‑side scenarios.
