Added, Draw Line and Draw Curve modes: added "Auto-finish drawing" setting. When enabled, the modes will automatically finish drawing when currently drawn lines and already existing level geometry form a closed shape.
Changed: sector-wise linedef flipping is now done using the new "Align Linedefs" action. "Flip Linedefs" action works the same as in DB2 again.
Changed: when a map was already loaded, using "Open Map" action will use that map's directory as the starting directory.
Changed: official IWADs can no longer be saved.
Changed: disabled lump ranges/duplicate entries checks for official IWADs.
Changed: wad type is now preserved when saving a map (previously all wads were saved as PWADs).
Changed: moved Updater.exe launch much closer to the editor termination point to avoid any chance of it closing the editor before it properly closes itself.
Updated ZDoom_DECORATE.cfg (A_Blast).
Updated documentation.
Fixed, Map Analysis mode: fixed a crash when trying to dissolve an invalid sector when one of it's linedefs referenced it on the both sides.
Fixed, Sectors mode: fixed incorrect undo description when deleting sectors.
Internal: joined declaration and assignment of some more variables.
Added "makedoorceil" game configuration property. Works the same way as "makedoortrack" and "makedoordoor", but for ceilings of door sectors.
Changed, Game configurations: the editor no longer tries to load DECORATE/MODELDEF/VOXELDEF/GLDEFS/REVERBS lumps when "decorategames" setting is not specified / is set to empty string.
Changed, General interface: "Tools -> Reload MODELDEF/VOXELDEF" and "Tools -> Reload GLDEFS" menu items are no longer shown when current game configuration doesn't support DECORATE.
Fixed a crash when pasting linedef/thing properties in Hexen map format.
Fixed, Visual mode: Visual Thing resources were not fully unloaded when resetting D3D device leading to crash when switching to the editor from a DX-using game engine (like ZDoom) running in fullscreen.
Fixed: in some cases, when current game configuration supported multiple script compilers, it was possible to open/create a map or change map options without selecting any script compiler.
Fixed, New Map Options window: default map name was not updated when switching game configurations.
Fixed: copied map element properties were not reset after switching to another map.
Fixed: stored textures for "Make Door" action were not reset after switching to another map.
Fixed, Game Configurations window: currently selected test engine name was not updated when pasting test engines from another configuration.
Fixed, Game Configurations: all "Heretic in Doom map format" configurations were using Doom sector effects list.
Fixed, Game Configurations: all "Strife in Doom map format" configurations were using Doom sector effects list.
Fixed, Open Map Option window: fixed a crash when switching to a map configuration with long texture names support enabled when the wad being open has no maps (this will probably never happen because of previous change, but let's be on the safe side...).
Internal: "uselongtexturenames" setting is now stored in map settings file, not in the program configuration file.
Fixed, Color Picker plugin: in some cases mouse movement was processed incorrectly.
Fixed, Color Picker plugin: float color value output was culture settings-dependant.
Resource List Editor: not existing resources are now shown using different color.
Map Options, Open Map Options, Game Configurations windows: a warning is now shown when a map resource doesn't exist.
Some minor fixes to Resource List Editor's context menu.
Updated ZDoom_DECORATE.cfg.
Texture browser form: added "Long texture names" check-box. It can be used to toggle between displaying long and short texture names.
Texture browser form: added "Show image size" check-box.
Texture browser form: image size is now shown differently.
Image Selector: added a button to toggle between long and short texture name.
Linedef info panel: long texture names are now displayed properly.
Sector info panel: long texture names are now displayed properly.
Fixed: "Save Screenshot" and "Save Edit Area Screenshot" actions were triggered multiple times when a child window was open.
Fixed: used textures should be always updated after using "Change map in current WAD" action.
Fixed, "Change map in current WAD": fixed a crash when trying to switch from a map with missing game configuration path.
Updated ZDoom_ACS.cfg.
Open Map in Current WAD: resources are now reloaded when current and target map's resources don't match.
Added some boilerplate to UniversalParser and PK3FileImage.
Internal: ImageSelectorControl now has "UsePreviews" property.
Internal: added ConfigurablePictureBox.
Updated ZDoom_DECORATE.cfg.
Configurations: all 64 game configuration are now available by default.
Game Configurations window: game configurations can now be disabled. This setting is mostly cosmetic. When a game configuration is disabled, it won't be shown in "game configuration" dropdowns in New\Open Map Options and Map Options windows. If a map's .dbs file specifies a disabled configuration, it will be picked as a map configuration anyway.
Linedefs mode: vertex insert preview logic used Highlight range instead of Stitch range (which is used when draw mode engages).
Visual mode: double-sided middle textures were not selected when using "Select" action with "with same texture" modifier.
Textures: some optimizations in patch blending code.
ZDoom ACS script configuration: added definitions for StrLeft, StrMid and StrRight functions.
Visual mode: added support for "fogdensity" and "outsidefogdensity" MAPINFO properties.
Sector Info panel now shows the number of sector's sidedefs as well as light and fade colors (UDMF only).
UDMF: Sector and sidedef flags are now copied/pasted when using "Copy Properties" and "Paste Properties" actions.
Fixed: in some cases default texture overrides were used even when corresponding option was disabled.
Sector Edit form: light and fade values were not saved when a value was pasted/entered into text box.
Sector Edit form: "reset value" button was not shown for light and fade values when selected sectors had different light/fade colors.
Reverted Open Map form changes from previous commit (my assumption that map marker is always empty was not correct...)
Updated documentation.
Snap Map Elements to Grid mode now works much faster and shows a message when completed.
Forced default textures are now only used in drawing modes.
Exception Dialog: long error descriptions were breaking window layout.
Map will no longer be shown in Open Map form if unrelated data is encountered inside of map namespace.
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
Added -resource command line parameter to specify additional resources for the WAD file loaded from command line (see cmdargs.txt for more information!)
