What's New

Overview

This page summarizes recent updates and important version milestones for System.Drawing.Managed. It highlights new features, improvements, and fixes across releases, and provides guidance on which versions should be used in production.

Versions 3.5.x found on NuGet are not supported and should be ignored. They were created exclusively for the Wisej.Hybrid branch to support mobile devices and are not compatible with the current System.Drawing.Managed 4.x line.
