Today we have released a refresh of Service Fabric.
At this time we have made SDKs, standalone and other packages 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 and download links for: Microsoft-Azure-Service-Fabric-Release-Notes-SDK-3.0-CU2-Runtime-6.1-CU2
