Java Edition Beta 1.6.3

Beta 1.6.3 is a version of Java Edition Beta released on May 26, 2011, which fixes some of the bugs and crashes in Beta 1.6.2.
==Changes==
===Blocks===
; 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===
; 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 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 furnaces dropping/duplicating their contents when they change state from lit to unlit or back.
