 It's about time I started a changelog! This will serve from now on as the main changelog for WorldEditAdditions.


-## v1.11 (unreleased)
+## v1.12 (unreleased)
+ - Add `//srect` (_select rectangle_) - thanks, @VorTechnix!
+
+## v1.11: The big data update (25th January 2021)
 - Add `//scale` (currently **experimental**)
     - Scale operations that scale up and down at the same time are split into 2 separate operations automatically (scaling up is always performed first)
 - `//count`: Make numbers human-readable

     - If you encounter any other issues with it over large areas (particularly 2000x150x2000 and larger), please let me know
 - Bugfix: Fix obscure crash in calls to `human_size` ("unknown" will now be returned if passed junk)
 - `//many` can now be used with commands with no arguments.
+ - `//conv`, `//erode`, `//fillcaves`: Treat liquids as air
+ - Add new [cloud wand](https://github.com/sbrl/Minetest-WorldEditAdditions/blob/master/Chat-Command-Reference.md#cloud-wand)
+ - `//conv`, `//erode`: Minor refactoring to improve code clarity

-## v1.10 (16th January 2021)
+
+## v1.10: The tidyup update (16th January 2021)
 - `//maze`: Fix some parts of generated mazes staying solid
 - `//maze`, `//maze3d`: Allow non-number seeds (existing seeds aren't affected - they will still produce identical output)
 - `//many`: Improve format of progress messages, add ETA

+## `//srect [<axis1> [<axis2>]] <length>`

 ```

 Note that the number there isn't in blocks (because hard maths). It is however proportional to the distance the wand will raycast looks for nodes, so a higher value will result in it raycasting further.
+
+## Cloud Wand
+The cloud wand (`worldeditadditions:cloudwand`) is a another variant the above _Far Wand_. It looks like this: ![A picture of the far wand](https://raw.githubusercontent.com/sbrl/Minetest-WorldEditAdditions/master/worldeditadditions_farwand/textures/worldeditadditions_cloudwand.png)
+
+Unlike the other 2 wands, this wand functions in an additive manner. Left-click on a node to expand the currently defined region (creating a new one if one isn't defined already) to include that node. Right click to clear the currently defined region.
+
+It has the range of the _Far Wand_ mentioned above too, so you can select nodes from a great distance. It also abides by preferences set via the `//farwand` chat command.

+```
+
+When working with many types of flowers the air values need to be higher to compensate. The best equation for the air value that I've found is `<desired spacing> * <sum of flower probabilities>`.

+## Grass Field
+Make a grass field
