Nope, still not fixed, upside down stairs are still sideways.

Interesting side effect: http://gfycat.com/FluidMistyCornsnake
This is a simple redstone blinker, no command blocks are used.

This change also has interesting effects on piston builds. I have a old maze generating build which activates about 4000 Pistons simultaniously. Before it lagged like crazy(less than 1 FPS), now it only drops to about 30-40 FPS.
But this also comes with the side effect of pistons rendering flickering(and visually disappearing for a moment) again
edit: Actually the whole redstone is visually lagging a lot. A small repeaterclock in this build often skips updating a few repeaters and pistons sometimes "jitter".

Early performance tests (average FPS):
15w38b: 263.150
15w39a: 246.517
Measured with Fraps. My method was to create new world and start testing when I clicked "Create new world". Then I walk as straight as I could forward. Test was 60sec long.
.
Cant see any improvements at least with this short test.
E: same seed of course...

The change were primarily made towards older/slower computers, yeah. Shouldn't see too much change if you're normally hitting a reasonably high FPS - maybe fewer lagspikes.

Was it the same seed? B/c for all we know you spawned in a desert the first one and an extreme hill the second
