This post has been updated to reflect just the Aeotec, ThingsOne, and Samsung SmartThings Hub 2018 (Hub v3) model release. For the Samsung SmartThings Hub 2015 (Hub v2) release details and conversation please see this post here.
For keen observers you may notice the V2 version is also now different that the hubs in this post. This is because the V2 update will also include a Lua Library change that is not part of the 59.8 release. For folks with hubs that have already updated to the 59.8 release, your hub will receive this Lua library update in the background over the next few weeks. This library update will help with some issues seen with a few community Edge drivers.
