Java Edition Beta 1.6.3

Beta 1.6.3 was mainly released to fix some of the bugs and crashes in Beta 1.6.2.

Changes

 * 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 you want it.
 * 2 blocks deep water doesn't prevent you from fall-damage anymore. You need at least 3 blocks deep water to fall in.

Fixes
3 bugs fixed


 * Fixed some block updates not updating lighting properly under some circumstances by reverting the "don’t always send block data" fix in 1.6.
 * Fixed a major CPU load issue in the server where a very tight loop would starve all other threads.
 * Fixed furnaces dropping/duplicating their contents when they change state from lit to unlit or back.
