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.
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.
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
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
