Visual modes: selected objects are not highlighted when "Toggle highlight" (H key) option is set to off. 
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).

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.

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.

Doom light levels were used even in maps in non-doom map format.

Tag Explorer plugin:
Elements list wasn't updated when map element was deleted.
Pugin wasn't disposed properly, which may led to Doom Builder 2 crash on map close.
Fixed plugin crash after opening another map.

Added UDMF Controls plugin.
Added "Snap selected vertices to grid" mode (Found in Edit menu).

Doom-style walls shading is now applied in Visual Mode

Updated to Doom Builder 2 SVN rev. 1549.

MODELDEFs and models can now be loaded from PK3 resources (does anybody know if models or MODELDEFs can be stored in WADs?).
Negative scale and zOffset are now correctly parsed from MODELDEFs (model surfaces may be inverted though).
Fixed a crash while reading MODELDEFs when Operation System's decimal separator was set to comma.
Fixed a crash when user changed Thing type in Visual mode to a new one with model override, which wasn't previously used in a map.
Fixed a bug introduced in 1.06 when models weren't rendered in Visual mode when Fullbright mode was on.
Non-breaking space is now correctly handled by all Doom Builder's data parsers.
ColorPicker plugin:
Fixed a crash when user attempted to open ColorPicker window to edit sector properties in Visual mode, using hilighted surface as selection source, without selecting anything before doing so. 

Added Color Picker plugin
Point, Flicker and Pulse light animation should now look almost exactly as seen in GZDoom.
Fixed a bug when editing thing properties in Visual mode didn't update visual thing.
Fixed incorrect doom-style walls shading when sector has "lightcolor" property set.
Fixed "Index was outside the bounds of the array in CalculateNormalsAndShading()" error.
GZDoomBuilder will now show error message prior to failing.

Fixed memory and performance issues in Visual Mode for things with 0 with or height. (note to developers: VisualMode::GetVisualThing(t) may return null!)

@ This should fix a problem with actions in combination with the Control key. Also removed the modifier keys check in the BaseVisual* classes OnEditEnd events, because I don't know why it is there and it prevents the user from assigning a key combination for that action.

@ Small improvement for the earlier committed sprite scale support. The DECORATE 'xscale' and 'yscale' Actor properties are now also supported, but I am not sure what the intended behavior is when one of these is used in combination with 'scale'. Right now 'scale' overrides them.

Fixed Thing update in Visual Mode when the Thing type is changed.

Added support for DECORATE 'scale' property in actors (sprites in Visual Mode now scale accordingly)

@ more fixes for auto-aligning hi-res textures: now takes the WorldPanning flag into account

- Fixed a problem in the linedef info panel where the linedef numbers was displayed instead of the sidedef number
- Fixed a problem where dragging geometry and things onto the window title bar locked up DB2
- Fixed a problem with wrong texture offsets of hi-res textures

- Scales are now generally accepted and exposed by the ImageData class instead of just ScaleWidth/ScaledHeight
- Camera offsets in Visual Modes now changeable in Game Configurations (default is Doom's camera position)
@ Some other stuff dealing with the new dockers I forgot what it's for.

@ fixed bug that caused a question message to save the map appear on closing after saving the map

- Fixed bug that allowed pasting geometry in visual mode (and the geometry becomes erroneous)

- Highlight and selection colors are now hidden while dragging textures.
