FWIW, the Rails security team says they're about to drop suport for 2.3, and this time they really mean it. (They say.) The current announced security policy is that once 4.0 gets released, they'll only be doing security patches for 4.0 and 3.2; 2.3 will be left out in the cold.
It's quite possible that someone will pick up the baton, as there still are a number of production 2.3 apps out there, and porting to 3.0+ --- more a "port" than an "upgrade" --- is a real pain. But I'm not sure anyone has stepped forward yet, and until someone does, you're taking your chances.
