Service Fabric SDK 4.2 to be removed from download center
https://github.com/microsoft/service-fabric/blob/master/release_notes/Service_Fabric_ReleaseNotes_101RTO.mdSays "Service Fabric runtime will soon be archiving and removing Service Fabric runtime versions less than 7.2 and older, as well as the corresponding SDK version 4.2 packages and older from the package Download Center." I'm wondering when is soon? And what will happen when the SDK is removed from the download center? Will the nuget package still exists/be listed? Will this old SDK stop working on new clusters? I see is recommended to install the supported SDK for the runtime version the cluster is running on. How soon after a cluster is upgraded should the SDK be upgraded? How far back a SDK is supported?
