Oops my bad. I was going by this: https://mojang.com/2015/08/windows-10-edition-beta-0-12-2-0/ . It says: "UPDATE: this is actually changelog 0.12.0.1 not 0.12.1.0! Blame our silly number bot (who has now been recycled) for any confusion. The patch also includes x86/32-bit support, which wasn’t mentioned in our earlier post."
