As the title says, I don’t exactly know where to go for the R127 download; I just checked Humble Bundle and I still only have the 8/20/2014 patch available to download.
Nevermind. For future reference for people who waited to access their alpha builds they were afforded via kickstarter: Right click on Stonehearth in Steam Library, then go to properties. Once in properties, go to beta and write steam unstable as the code after selecting latest.
