Testnet forked to HF20 last week, running the devnet branch, though only depends on #1744 and #1734 (both separately merged now).
Edit: Also adds a commit that makes disabled OXEN registrations fail with a proper message in HF20+ (which currently applies on testnet, and substantially confused me by letting me prepare a registration and then gave a misleading error message from the wallet when I tried to submit it).
