Please review the release notes for more information about the changes included with this update. SocketTools 11 supports the current release of Windows 11 and Windows Server 2025.

For the SocketTools Subscription and .NET Edition, this update includes builds which use the latest .NET SDKs. If your projects are using .NET 6.0 or .NET 7.0, remember that these versions are no longer supported by Microsoft. We will continue to include assemblies which target those versions to assist with migrating your projects, but it's recommended that you upgrade them to the .NET 10.0 LTS release.
