Update notes, please read the following carefully:
The latest build has fixed considerable issues when using "send-before-history: true" (i.e. between 2 and 8 times speed increase in visible world-editing).
Before this build, tile entities may have been removed when executing history commands and blocks that were placed between edits/using history commands may not have remained/been removed properly (including other edits).
This configuration option will remain under experimental for the foreseeable future until enough brave editors have tried it with success. We recommend using this option if and only if you have frequent (hourly) backups for the time being, however, from our (slightly limited) testing, the aforementioned issues have not yet occurred (can't prove a negative, so that doesn't mean they don't still exist! If you discover one, please raise an issue on our issue tracker) and so we are happier to advise people that this option is "not quite so experimental".

If you have "send-before-history: true" and run a //set on pre-loaded chunks you might find upwards of 50mil blocks/sec being set (if you ignore the number it tells you cos that's wrong at the moment).
This improvement also has the added bonus of not having other people editing affect the speed of your edit nearly as much if at all (for those that want to know, there was some very needless synchronisation between edits which has now been rectified).

Fixes:

- Fixed writing invalid tile entities to schematics
- Fixed odd biome placement of //replace $savanna $jungle_hills (example)
- Fixed chests and other containers being empty after undo/redo
- Fixed "-f" flag for //ceil and //up
- Fixed AIOOBE when using fixlighting on a big selection
- Fixed //snow and //thaw not updating grass blocks properly
- Fixed //undo not working for //line
- Fixed brush size 0/1
- Fixed //image and image brush
- Fixed //distr and //count not counting all air blocks and natural warped roots
- Fixed //hsphere only creating a few blocks
- Fixed loading of invalid schematics (Formerly known as "This schematic version is currently not supported)
- Fixed origin point not being read and used when loading and pasting schematics.


Changes:

- The clipboard (//copy) is no longer limited to max. 2147483647 blocks.
- Correctly "offset" entities in the schematic, and add a legacy mode for loading old FAWE schematics with entities required.
- Add an FAWEVersion to the metadata of schematics created, allowing us to use the FastSchematicReader over sponge to load, read, and write schematics way waster.
