So, non-Windows Insiders get .NET Framework CUs but Beta/Release Preview channels users don't? Why do you separate the Dev channel from UUP if it shows up on it? On UUP Dump there's a more recent EP/Feature Update than the one which shows up on the Updates Overview. So, there are non-channel updates called Preview too like at least some Catalog updates? May Catalog updates be more up-to-date than Channel ones?
