- 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).

- 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()

- 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).

- 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).

- Expanded Inventory travel code to also support travel other actors such as GameInfo and Mutators.
- Added Actor.bOnlyOwnerRelevant to force actors to only network to Owner player.

- Added Actor.UserData (map<name,any>) to store custom mod data with an actor.

- Added function Engine.GetEngine to grab current engine reference in UnrealScript.
- Added new parm to SetTimer to pass in data to timer callback function ('any' data).

- Added new parm TraceFlags to Trace functions to allow you to define what actors to trace after.

- Changed download error messages to be also printed to the HUD/console.
- Made AttachMover also attach actors on clientside (mainly to fix elevator corona on Terralift).
- Added an option to player console to enable script error printing to in-game console.
- Added Monocrome bitmap compression (mainly for single colored masked textures like fonts).
- Fixed various bugs with demorecording (added support for older 224-225 demos, added HUD features, fixed demo scoreboard etc).
- Made it also possible to pause demo playback (also made it skip pauses during demo playback).
- Fixed a rare crash with trying to call SetOwner onto an invalid actor or causing an infinite owner chain (Actor A owns B which owns A etc).
- Compressed int replication a bit more when replicating low values.
- Disable initial garbage collection when booting up the game (waste of time).
- Made it impossible to try to load package 'nul' to prevent malicious loading crashes.
- Made commands 'Start' and 'Open' always delay mapchange until end of tick to prevent 'Admin' command from crashing the server when using it (i.e: Admin Open). Also made said commands pass in as Level.ServerTravel event when called on server to allow clients properly to reconnect to new map.
- Added Volumes support from UnrealEngine 2+ (which can be used to create brush shape collision shapes or triggers to levels).
- Made LadderTrigger a Volume instead, also various fixes to ladder:
     - Player properly hops off the ladder now at top.
     - Added a flag to allow player to strafe on ladder (you must have bDirectional enabled).
     - Added a flag to enable/disable directional ladder which makes you drop off the ladder if you look away from it (must also have bDirectional enabled).
     - Pressing jump key while holding backwards now makes you now jump off ladder backwards.
     - Added a value to control climbing speed on the ladder.
- Added INI file option 'LangPath' which can be used to specify director of language files (like .int).
- Added a variable to SkyZoneInfo which allows you to make sky move in relative to player camera position.
- Added support for static light static mesh movers.

- Added Actor.bBlockAISight which makes AI not be able to see through the actor (must have bCollideActors enabled but can be non-blocking).

- Added an in-editor event callback (EdBrushDeployed) which is called when actor was added to level with a brush.
- updated PackageFlagCommandlet to change package flag bits only instead of loading and resaving the packages.
