Minecraft Snapshot 13w10b / 1.5 pre-release expected soon

Minecraft released a new snapshot for us to play around on.  Snapshot 13w10b.   Containing bug fixes and more bug fixes! This post also tells us to expect the pre-release snapshot of 1.5 sometime today most likely as this snapshot and information was released yesterday, Once pre release 1.5 comes out instead of making a new post I'll just update this one.

 The 1.5 pre-release is expected tomorrow!  In the meantime, help test out the latest round of Snapshot goodness!

Notable changes:

• Dispensers and droppers will now only fire once when they receive a redstone signal. To fire again, the signal must be turned off and on again. (Previously a dispenser would fire whenever it had a signal and a nearby block changed.)
• Redstone and components stay powered after unloading chunks
• Dispenser and Dropper shooting out when updated
• Server crashes if spaces are input on the console
• Night Vision Potions that are edited to last longer create a potentially seizure-inducing flashing sky background.
• Furnace interface occasionally closes when adding fuel, deleting all items in the furnace
• Named Mobs Don't have Named Babies
• Getting into a minecart with a mob in it crashes minecraft
• 2 Hoppers funneling unstackable items into a 3rd Hopper at the same time cause the 3rd Hopper to not funnel items into a container
• Dispensers continually shoot/use certain items like water buckets and flint&steel
• Comparators still giving off power when hopper inventory is empty
• Animals can breed over distances up to almost 8 blocks when only seperated by fences
• Message "THIS TOO" in console
• Full hoppers feeding into full hoppers causes the forward hopper to stall
• Adding items to brewing stand using dropper does not change state of comparator
