Rename //find to //highlight and worldedit.find to worldedit.highlight, add //allocate and worldedit.allocate as well as related documentation. Improve documentation by fixing a few mistakes and adding return signatures.
Fix //load and //allocate for old WorldEdit files.
Quick and dirty fix for metasave not saving ItemStack instances in node metadata inventories.
Fix the missing command //suppress <node>.
Many thanks to Smitje for providing a working example of roations.

Changes: fixed rotation and transposition of non-sqaure regions, makers are now moved to the new region boundaries after rotation/transposition, small consistency fixes, finally fix the /hide command.
Only dig air Nodes
Rename //dig to //fixlight
Fix Code
Fix Code again
Fix my Code again (I've use Python too much)
Finally fix anything
Change all references of //dig to //fixlight, document the changes, fix a small typo.
New command: //orient, that rotates oriented nodes such as furnaces around the Y-axis by a specified angle.
Add //homogenize, //lua, and //luatransform commands, as well as their documentation.
Replace //homogenize with //replaceinverse (//homogenize x is equivalent to //replaceinverse air x), add documentation for it.
Require `server` priv for Lua commands.
Use rounding rather than flooring for more intuitive player position setting.
Fixed bug where unmodified axis used pos1 coords instead of pos2 coords.
Fix styling issues in Chat Commands.md
//metasave and //metaload are now superceded by //save and //load's new functionality. worldedit.deserialize now supports every version of the WorldEdit format that has ever existed, and the new worldedit.valueversion uses file characteristics to determine which type of file format a given file uses. The new WorldEdit file format is the same as the one used by MineTest for serializing data, and is capable of storing arbitrary data, as well as leaving fields for future improvements. In other words, this is the last forward-compatibility breaking change that will be made to the file format.
