Today we have released a new version of the SDK and are in the process of rolling out a new runtime to Azure clusters.
This release is both a refresh to clusters running in Azure (Linux and Windows), a refresh to the .NET SDK and the first 6.0 release of Service Fabric for Windows Server (Standalone).
At this time we have made the SDK available for download and are about to start the upgrade and roll-out to clusters in Azure. The upgrade will go on over the next days, so expect your clusters to upgrade anytime soon, if you are running with Automatic upgrade in Azure.
Check out the release notes for the details: Microsoft-Azure-Service-Fabric-Release-Notes-SDK-2.8.CU1-Runtime-6.0.CU1
