3.1.0-alpha5 should be really close now (another build tests round should finish today, and if everything shows green light this time, we should have at least the source tarballs of the alpha5 out within 24 hours from now). Assuming no catastrophic failures forcing us to reiterate, this should be the last alpha release of 3.1, and we move to beta next.
