Linedef colors were not updated properly when a map format was changed and were causing an exception in some cases.
Vertices mode: linedef in split linedefs range was redreawn incorrectly in some cases.
Updated "Sector 3D Floor" (160) action: set default Type to Solid (1), added "Use Arg5 as Line ID" flag to Types, changed arg5 name to "Line ID / Hi-Tag".
Added "GetUserCVar", "SetCVar" and "SetUserCVar" functions to ACS configuration.
Set width and height of several actors to 0 in game configutrations (non-zero sizes were added as a workaround when GZDB was not displaying actors with 0 width and height in Visual mode).
Added several sprites to game configurations.
Visual Mode, UDMF, Visual Vertices: you can now press "Delete" key to clear z-offsets of selected vertices.
Visual Mode, UDMF, Visual Vertices: the logic, which decides whether z-offset should be kept or removed, was not working properly.
Visual Mode, UDMF: Auto-align Textures (Y) action was not working properly when targeted texture was lower wall without "Lower Unpegged" flag.
Visual Mode, UDMF: "Auto Align Textures" actions now work on slopes.
Visual Mode, UDMF: Floor/ceiling texture rotation is now taken into account when moving texture offsets with arrow keys.
Visual Mode, UDMF: Fixed a bug in floor/ceiling texture dragging by mouse.
UDMF: Reset texture offsets action now works on floors and ceilings.
Vertices mode: when a linedef is within Split Linedefs range, it's now highlighted using Info line color.
Point Thing at Cursor action: action now works when used from menu, changed default shortcut to Shift-L. You can now hold Ctrl to point Things away from cursor.
Visual Mode, UDMF: "Auto-align Textures Y" action now applies vertical scale of first (highlighted) surface to the rest of aligned surfaces.
Linedef Edit Form, UDMF: lower sidedef texture offsets were never displayed.
Some more changes in auto texture alignment of newly drawn lines.
BuilderEffects plugin should compile now.
Added Selection Groups options to Edit menu.
Selection Groups can now be cleared using either Edit -> Clear Group or Ctrl-Shift-[group number] shortcut.
Toolbar button groups can now be toggled using context menu. Hold "Shift" to toggle several button groups at once.
Fixed incorrect behavior when 2 linedefs are merged into one after deleting a vertex, when a newly created linedef overlaps existing geometry.
Visual Vertex handles were not updated when sector's floor or ceiling height was changed.
Rendering of (G)ZDoom rendering effects (slopes, 3D-floors etc.) can now be toggled in GZDoom Visual mode (default key is "Tab", action is Visual modes -> Toggle GZDoom rendering effects)
UDMF: UDMF texture offsets can now be edited in Sector and Linedef edit forms.
Floor and ceiling textures are now dragged properly in GZDoom Visual mode.
Floor and ceiling textures are now moved more predictably by arrow keys in GZDoom Visual mode.
Walls texture coordinates are always rounded when moved by arrow keys in Visual modes.
Linedef info panel: relative UDMF light values are now shown like this: 16 (128), which means "UDMF light value" ("total surface brightness (UDMF light value + sector brightness)")
Player is now spawned at camera height when testing from current location in Visual modes.
Focus is now properly restored after testing from current location in Visual modes.
Updated Heretic_sectors.cfg and Heretic_things.cfg as described here: http://www.doombuilder.com/forums/viewtopic.php?f=11&t=357
Changed sprites of artifacts in Hexen_things.cfg to proper ones.
Renamed Skulltag configs to Zandronum
Error Checks Mode: added linedef index to message text of all linedef-related errors.
UDMF: wall texture offsets are now rounded when user edits them via cursor keys or mouse dragging (because they are stored as integers anyway).
UDMF Controls: increased precision of position and scale controls numeric inputs to 2 decimal places.
Sector/Linedef info panels: in some cases incorrect default values were shown for scale.
Sector/Linedef info panels: numbers are formatted more properly.
UDMF: changing brightness of a wall or ceiling in GZDoom Visual mode will change brightness of selected surface, not sector brightness.
Sector and Sidedef info panels show additional info if a map is in UDMF format.
Fixed: GZDoom menu panel wasn't updated when a map was opened via "recent files" item click.
Event lines for "event activators" (ActorMover, Camera and things with Thing_SetGoal special) are now drawn with different color.
Fixed a crash when a Thing with arguments is pasted in Visual modes.
Several other small fixes.
Fixed config error in ZDoom_things.cfg.
Fixed config error in ZDoom_ACS.cfg
Relative mode is set to false by default.
Limits of Brightness slider were set after setting it's value, so values greater than 100 were set to 100.
Fixed a bug when a plugin tried to access 3d-floor-specific stuff of walls, which weren't part of 3d-floor.
Color Picker plugin: added float representation of current color (like 1.0 0.54 0.29). Should make editing of GLDEFS light definitions easier.
Fixed: inability to change 3d-floor height when control sector is too far away (further than current View distance).
Fixed: "Frame" property wasn't red by MODELDEF parser.
Fixed: PK3 archives are no longer locked when GZDB is running, so you can change their contents without closing the editor.
TEXTURES patches can now be loaded from anywhere inside resource.
Configs: things from "Cameras and Interpolation" and "Boom Items" categories weren't rendered in Visual modes.
Configs: several new icons are now used for things.
Reverted sectors rendering from 1.12b, because it was done in too hackish way and was causing more and more problems. Models rendered height is now 25% lower instead.
Models rendering height can be toggled between normal and 85% in Preferences->Appearance->"Scale models in Visual modes"
Fixed several small bugs here and there.
Things can now be rotated in visual mode.
Added JPG and TGA image format support.
Fixed: TEXTURES files with names other than "textures.ext" will now be loaded (as an example, files named like "textures.something.txt" or "textures_walls.ccp" will be loaded by (G)ZDoom, but not by Doom Builder 2 or previous versions of GZDB).
Fixed: textures defined in TEXTURES have higher priority in (G)ZDoom than images with the same name in "textures" folder.
Fixed another possible crash when MODELDEF is reloaded.
AngleOffset, PitchOffset and RollOffset MODELDEF properties are now supported.
Fixed a crash when editor tries to display a model for an actor without a valid sprite in Visual mode.
Fixed a possible crash when MODELDEF is reloaded from 2d-mode.
Fixed several things in Doom2_things.cfg.
UDMF Controls plugin:
Fixed several bugs in plugin's sliders logic.

ACS scripts from #include and #import directives are now shown in Script name/number dropdowns.
Fixed several cases when ACS scripts lists used in Edit Thing and Edit Linedef forms wasn't updated when they should've (i.e. after compiling a script).
Things can now be cut, copied and pasted in Visual modes.
Sector geometry was not updated properly after Undo/Redo in GZDoom Visual mode.
Fixed an error when user selects multiple things and attempts to view their properties in Doom map format.
Added Decorate and Modeldef syntax hilighting, autocompletion and item recognition to Script editor.
Script Editor can now autodetect several script types when you open them (currently ACS, Decorate and Modeldef scripts are recognized).
Tag Explorer: fixed a bug when Tag Explorer update can block keyboard keys release detection logic.
Replaced all doubles with floats.
Script Editor:
Navigator drop-down now updates automatically.
Navigator drop-down now also works for external files.
Added Navigator drop-down support for Decorate and Modeldef.
