there's a change to Nether portals

[Thorin]

So every nether portal I created, I made sure that they were aligned in the same direction so that you could walk into one at one end and not have to turn around to walk out of it at the other end.  For instance, if you entered nether portal in the overworld and were facing north, you'd be facing north in the nether and be able to walk straight out.

Well, with the 1.5 update the nether portals now turn you 180 degrees.  This means that if you're walking north into a portal and wait for it to teleport you, you're now pointing south.  I built my nether portals so that there's a wall behind them, though, so that means I'm actually facing into a wall and can't walk forward until after I turn.
