We're starting to wonder if the Mojang team does anything but eat, sleep and work on "Minecraft," because the Swedish dev team has the sixth "Minecraft" 1.5 Redstoneupdate snapshot of the month.

As the "Minecraft" 1.5 Redstone update release draws closer, Mojang has let loose another preview snapshot to give players an idea of what they can expect when the next major "Minecraft" update launches during early 2013. While it certainly doesn't introduce as many changes as the prior "Minecraft" snapshot, today's release of build 13w04a does bring us one step closer to an official release of the "Minecraft" 1.5 Redstone update.

Though things could obviously change as players have more time to dig into the contents of "Minecraft" snapshot 13w04a, the latest Redstone update preview doesn't appear quite as packed with new features as last week's "Minecraft" preview build. Where last week's release of the "Minecraft" 13w03a snapshot introduced tougher mobs, Droppers, Hopper minecarts and more, the new Minecraft 13w04a snapshot primarily brings changes to the game's existing minecart and track systems. Players will also find that mobs are now scared of minetracks/minecarts in Minecraft snapshot 13w04a as well.

The team at Mojang increased the number of blocks that can be carried by minecarts, finally giving players the ability to put a mob spawner on rails, and also added an easily accessible scoreboard/leaderboard to the game as well. Mojang also updated the Dispenser and Dropper blocks, giving players the ability to set their vending machines/traps to face any of the six directions for the first time.

Much like the release of snapshot 13w03a, "Minecraft" snapshot 13w04a also introduced a host of new bug fixes to the game, including some of the game-crashing issues which debuted alongside the new Hopper minecarts. Some of the promised updates to the "Minecraft" Redstone system were also delivered with snaps 13w04a, including fixes for errors caused by variable-strength Redstone creations and new Redstone-powered devices built near existing Redstone systems.

It's been a big month for the "Minecraft" dev team, with the release of multiple 1.5 Redstone update snapshot previews and Mojang announcing that the company has officially sold more than 20 million copies of the "Minecraft" for PC, Xbox 360, iOS and Android devices. Perhaps most surprisingly, while "Minecraft" debuted on the PC back in May 2009, it's already sold more than 5 million copies via Xbox Live Arcade.

Unfortunately, there's still no word on an official release date for the "Minecraft" 1.5 Redstone update, though the higher than average number of snapshot releases is certainly a good sign. While Mojang typically releases a preview snapshot each week, the dev team is releasing an average of one new "Minecraft" snapshot every five days currently, and there's still time to slip in one more "Minecraft" 1.5 Redstone update snapshot before the month ends.
