Changed: "+++" and "---" prefixes are now incremented on the first step instead of the second when used in any numeric inputs, which support prefixes, except action arguments.
Fixed, Visual mode, UDMF: texture offset/scale/rotation changes were applied several times when used on several 3d-floor floors/ceilings linked to the same control sector, when using "Move Texture Offsets" / "Change Texture Scale" / "Rotate Texture CW/CCW" actions.
Updated ZDoom ACC (DamageActor).
Updated ZDoom_ACS.cfg (DamageActor).
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.
