Nutrient.NET SDK 14.4.9 improves image-processing performance and fixes licensing and image-loading issues.

Below are the notable updates in this release.

## Image processing

Raster operations used by [`DrawGdPictureImageOP`](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14.API~GdPicture14.GdPictureImaging~DrawGdPictureImageOP.html) and [`DrawFilledRectangleOP`](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14.API~GdPicture14.GdPictureImaging~DrawFilledRectangleOP.html) are faster. This release also fixes loading standalone JBIG2 (`.jb2`) images, including multipage files.

## Licensing and reliability

The SDK no longer prints the licensing banner and licensed-feature list after a production license key is registered. Fixes also prevent process crashes when multiple threads register a license key or check licensed features concurrently. They also restore feature tracing in trial mode and for Windows Presentation Foundation (WPF) viewer controls.

## Nutrient CLI

The PDF conversion commands add DWS account sign-in, automatic guest access, and persistent usage reporting.
