Decoupled plane equation slopes from sector heights. This means that changing sector heights will not change those slopes (use the offset box in the "slope" tab of the Edit Sector Dialog instead)

Added option to lock texture offsets of 3D floors when dragging the tagged sectors

Texture browser: input boxes don't lose focus anymore when the mouse is moved into the texture list area. Fixes #369.

Changed the ambient sound drop down menu of ambient sound things to natural sort order. Resolves #406.

Fixed a crash that happened when the script window is opened but minimized, the script has syntax errors, and then the map is saved. Fixes #402.

3D Floor Mode: allow pasting for texture names with more than 8 characters in the 3D floor editing window

Move vpo native code into BuilderNative as it is easier to manage. The plugins folder doesn't support including native dlls properly anyway.
Fix visplane explorer busy looping when waiting for data and reduce the used core count to 75% of the total available
Made vpo native code thread safe, removing the need for ungodly DLL patching hacks

Significantly reduced video memory usage when pasting sectors. Should also significantly increase speed when pasting many sectors. Fixes #400.

Fixed a bug where the DECORATE parser got confused by wrong tokens after starting the states definition. Fixes #374.

Fixed multi select in 3D Floor Mode to work when starting to drag inside a sector

Fixed a crash in Edit Selection Mode when visual sloping was previously used to make the slope of a sector perfectly planar

Moved smart grid transform into Linedefs Mode and Vertices Mode, so it also works when simply highlighting a linedef or vertex. When doing smart grid transform on a linedef it'll also use the vertex closest to the mouse cursor as the origin instead of always the start vertex

Added "Smart Grid Transform" action that sets grid transformation based on the selected elements. Vertex selected: set grid origin to that vertex. Linedef selected: align grid to that linedef. Nothing selected: reset grid transformation to the default coordinate system. No default key bound.

3D Floor Mode: using tab in the 3D floor editor window now cycles through the input fields in a sane order

Fixed a crash that would happen when the line slope things (9500/9501) are used but the linedef they are tagged to doesn't have a front sidedef. Fixes #398.

Added option to select behavior (Tools -> Preferences -> Editing) of scaling when auto-aligning textures on floors/ceilings (use base scale of 1 (default), use current scale as base, never scale)

Custom types for user defined UDMF fields could cause problems when fields with the same name used different types, so they are disabled for the time being (only bool, int, float and string are allowed now)

Update things before adding their geometry in visual mode so things don't go awry when realtime editing them. Fixes #393.

Aligning textures on the X axis now works correctly with negative scale values when world panning is not enabled.

There can be multiple different ambient sounds with the same sound name, so add the index to the name to differentiate them. Fixes #390.

Fixes for raisesectortonearest and lowersectortonearest action when used on slope handles to account for float rounding errors

Copy resource bitmaps before using them on a worker thread
