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: 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.
Dynamic lights defined in GLDEFS are now rendered in Visual modes (currently only one light per Thing is supported).
Several values from (Z)MAPINFO are now used in Visual modes.
Added "Reload GLDEFS", "Reload (Z)MAPINFO" and "Reload MODELDEF" menu options (in "Tools" section).
MODELDEF parser now checks which model(s) is/are used in first frame.
Dynamic lights are now created with more meaningful default parameters.
Added errors and warnings indicator to main window.
