Bitcoin Core 0.12 with addrindex released by btcdrak

You can get it here:

It seems the same as 0.12rc1, but there are Gitian-generated binaries signed by btcdrak.

In terms of bitcoin.conf settings, maxmempool is new (300MB is the default, 30MB should be enough for most), while relay and the minimum fee settings that used to be necessary in 0.11.2 are not needed in 0.12.
