CheeseMod 1.5.1_b1 Changelog:
Download (requires build 2691+) - Other Versions
/storm, /time, /mode, /item and /me will now work with command blocks
Re-enabled the vanilla /time set [whatever] command, which works basically the same as /time [whatever]
Replaced /block type with /block set
Added the vanilla /tp x y z and /tp [player] x y z commands.
Changed /give to use the original vanilla format for command block compatability, /item still uses the simpler /item [item] [amount] format.
/block sign [#] will set that line to blank now.
Non-player entities travelling through portals has been temporarily disabled due to a 1.5 related error.
