The masternode payment fork has been postponed until May 25th due to some issues on testnet over the last couple of weeks. A few issues have cropped up and we want the code to be more thoroughly vetted before turning it on for mainnet. This is expected to take less than a week, but to ensure we have enough time we've chosen May 25th.
Good choice Evan. I saw all the new binaries popping up and was getting slightly worried it was going to be rushed with some fatal flaw in the code. Good luck squashing all those bugs this week!
