- Added support for map properties (map<typeA,typeB> MapValue) aswell as accessors to it:
     out typeB MapValue[typeA] - Simple read value by key value, creates new key if not found.
     bool MapValue.Has(typeA, optional out typeB) - Check if has (and optional grab key value).
     bool MapValue.Remove(typeA) - Remove a key from the map.
     MapValue.Empty() - Empty map.
- Added dynamic array call macros (it will compile as Array_Size/Array_Insert/Array_Remove calls):
     int Array.Size() - Grab array size.
     int Array.SetSize(new size) - Change array size and return new array size.
     int Array.Empty() - Empty array and return new array size.
     bool Array.Insert(index,count) - Insert new entires at offset of array (return true if succeed).
     bool Array.Remove(index,count) - Remove entires at offset of array (return true if succeed).
- Added Map and Dynamic array iterators: foreach Map(out typeA, out typeB) or foreach Array(out valuetype).
- Fixed script compiler to prevent modifing constant dynamic arrays.
- Made Object.GetParentClass a static function and parameter to be optional (if parameter is not set it will return current class parent).
- Changed Object.GetDefaultObject return in same metaclass type as input class parm (same way as Actor.Spawn does).
- Added 'SizeOf(Object class)' compiler directive to return bytes of size of an object class.
- Added support for declaring 'private' functions.
- Added Object > LogHandler object to allow UScript to sniff and block log lines.

- Made editor save viewport coordinates with the maps.

- Fixed coronas and sprites to fade out from distance fog.
- Optimized render by disabling surface sorting when not needed.
- Fixed a bug where skybox would turn into a HOM when viewed through a mirror reflection.
- Made windows mouse pointer usable in-game on fullscreen mode (mainly for UMenu).
- Added support for DynamicCorona to have directional light ray texture (which is only visible from the sides of the corona).

- Added IK solvers for SkeletalMeshes for easy animation blending (such as head turning, limb rotation or foot placement).
- Added support for SkeletalMesh hitboxes for individual bones (and group them to bodypart type for modders to use).
- Made it possible to enter spaces in names in properties and defaultproperties blocks.
- Added ZoneInfo.MinWalkableZ to tell physics engine how steep slopes Pawns can walk on.
- Fixed preferences window to correctly save config to ini if you add/remove dynamic array entries.
- Improved Physics PHYS_Spider to work better at finding walkable surfaces and attempt to yaw actor towards desired rotation.
- Fixed a rare AActor::BeginTouch/EndTouch crash.
- Implemented Alt+F4 hotkey to exit the game instantly.
- Improved Log window to support command history browsing (up/down arrows) also properly support selecting/replacing parts of text or insert text in middle of command.

- Added actor function: function bool HasMeshHitBoxes() to quickly check if actor uses SkeletalMesh with HitBoxes (to make Trace check against HitBoxes instead of collision cylinder, set Actor.bTraceHitBoxes=true, to check which HitBox bodypart type was hit by the trace, check Actor.LastHitBox.
- Added a new parameter for DrawDebugLine function for making them permanent in level (or until you call ClearDebugLines): static function ClearDebugLines()
- Fixed #exec directives to support unlimited characters length for the command.
- Added Pawn.bNoPhysicsRotation to free Pawn from physics based rotations.
- Optimized some of UnrealScript code by moving some of base Actor code to C++ codes (TriggerEvent/HurtRadius).
- Added function to Pawn: iterator function AllInventory to allow for fast and safe iteration of Pawn inventory chain.
- Fixed Y/N questions in UCC.exe to not skip second Y/N question if multiple ones comes after each other.
- Added an event to Object: event OnPropertyChange( name Property, name ParentProperty ) to notify of a property change in the object (called from properties window, SetPropertyText or SET consolecommand), also called in editor.
- Added to LevelInfo: array<Object> CleanupDestroyedNotify to make custom objects receive cleanup destroyed notifications (to change destroyed actors to None in order to avoid crashes, player console is added by default to this array upon map load).
- Made defaultproperties importer throw a warning if you reference to an object that wasn't found.

- Fixed DebugLines to draw in editor too.
- Added to MeshBrowser a menu option to export mesh import lines to clipboard (incase you tweak them in editor).
- Made properties window automatically pop-up tooltip of the property when you hover the mouse over the line for a second.
- Fixed properties window to show correctly struct member values if multiple actors are selected.
- Fixed properties window color selection preview color if Alpha value was non-zero.
- Made edit constant variables red colored in properties window and made the textlines selectable so that you can copy the value to clipboard (such as Name or Class name).
- Moved all hidden (uncategorized) properties to a "Hidden properties" category in properties window, also color coded to red.
- Added an option (enabled by default) to make rotation angles show in radii angles (0-360 range) rather then UU angles (0-2^16 range). Setting is at: [Core.System]
UseRegularAngles=False
- Added an option (disabled by default) to allow Actor properties window close itself if no actors are selected: [Core.System] CloseEmptyProperties=True
- Optimized Editor group browser (also added a second checkbox to lock actors, in order to keep them visible but have them unselectable).
- Added a warning if you try to open a map outside of working directory.
- Fixed so that maps that have missing packages to be allowed to be partially loaded (it will still give a map load warning at first and asks Y/N if you want to load anyway).
