Well, to clear up things for you, here is the list of Official SUPPORTED devices: While this is nothing new in terms of build updates, but I’m afraid to say, there is something that brought disappointment to many die hard Windows Phone fans as responsible people at Microsoft has yet again ditched support for some Lumia devices and those will no longer receive further updates. Microsoft has just started working out on the next major update Redstone 3 for Windows 10 on Mobile devices and lately, pushed Build 15204 for Insiders on the Fast Ring. This will ensure you to continue receive cumulative updates going forward.

If you are currently on the Fast Ring / Slow Ring, choose Release Preview.

Once done, you can now join Release Preview Ring and stay on it. Here is how you can join Insider Program on Windows 10 Mobile. If you have an unsupported device that's not already on 15063, it won't get 15063. In case you weren’t part of insiders program and your device is still on Anniversary update (Build 14393.xxx) you will have to join Insiders program and switch to Slow ring to get Build 15063.XXX. So, thing is if your device was already in Insider program and on Build 15063, you will start getting latest cumulative Builds like the latest Build 15063.251. Now many readers are facing issues in getting Creators Update via Release Preview program, even when their devices are in above list.
