<a name="release-2022-05-27-windows.changes"></a>

In this latest release, we're adding AWS Elastic Beanstalk support for .NET 6 on the Windows Server platforms.

With this release, you can use Elastic Beanstalk to deploy your .NET 6 applications to your AWS Windows environments. .NET 6 is supported on Windows Server 2016 and later. Also, .NET 6 has improved performance for ARM64. For more information about how AWS can help you leverage .NET 6, see [.NET 6 on AWS](https://aws.amazon.com/blogs/developer/net-6-on-aws/) on the AWS Developer Blog.

For more information about .NET 6 features, see the Microsoft website [What's new in .NET 6](https://docs.microsoft.com/en-us/dotnet/core/whats-new/dotnet-6).

In addition to introducing .NET 6 on the Windows Server platforms, some additional changes are included for the Windows platform in this release. They are listed in the following table.
