Minecraft:Java Edition Beta 1.6.3

Beta 1.6.3 is a version of Minecraft:Java Edition Beta released on May 26, 2011,<ref>Template:Twon</ref><ref>Template:Tweet</ref> which fixes some of the bugs and crashes in Minecraft:Beta 1.6.2.

Changes

Blocks

Minecraft:Water

• Water that is 2 blocks deep no longer prevents fall damage.
  • Players need at least 3-block-deep water to prevent fall damage.

General

Minecraft:Options

• The renderer is now capped at 100 fps while there are chunks to be generated. The excess time will be spent generating chunks instead of rendering frames.
• The "limit framerate" option now limits the game to 40 fps and will spend at least 10 ms per frame sleeping.
• The "limit framerate" option has been reset to "off" for all players, enable it again if wanted.

Fixes

3 bugs fixed

• Fixed some block updates not updating Minecraft:lighting properly under some circumstances by reverting the fix in 1.6 that lead to block data not always being sent.
• Fixed a major CPU load issue in the server where a very tight loop would starve all other threads.
• Fixed Minecraft:furnaces dropping/duplicating their contents when they change state from lit to unlit or back.
