All classes were reviewed apart from VisualServer for which no argument name is documented at all.
While doing this review, I found quite a few bugs that were fixed either in earlier commits or this one (mostly documentation bugs though, i.e. some arguments were listed at the wrong place).
A general speedup should be apparent, with even more peformance increase when compiling optimized.
WARNING: Tested and it seems to work, but if something breaks, please report.
-Added Navigation & NavigationPolygon nodes
-Added corresponding visual editor
-New pathfinding algorithm is modern and fast!
-Similar API to 3D Pathfinding (more coherent)
-=-=-=-=-
-Fixed problem with scaling shapes (#827), related to not taking scale in consideration for calculating the moment of inertia
-Added support for multiline strings (or comments) using """
-Save subscene bug, properties not being saved in root node (#806)
-Fix Crash in CollisionPolygon2DEditor (#814)
-Restored Ability to compile without 3D (#795)
-Fix InterpolatedCamera (#803)
-Fix UV Import for OBJ Meshes (#771)
-Fixed issue with modifier gizmos (#794)
-Fixed CapsuleShape gizmo handle (#50)
-Fixed Import Button (not properly working in 3D) (#733)
-Many misc fixes (though no new features)
-=-=-=-=-=-=-=-=-=-=
Build System:
-Big clean up of SCons, changed how builds are done to a much cleaner method (check the Github Wiki for instructions).
-Deactivated BlackBerry10 (sorry), if no mantainer found (or BlackBerry does not send us a Passort ;), platform will be removed as we have no longer devices to test.
Engine:
-Removed deprecated object and scene format (was in there just for compatibility, not in use since a long time).
-Added ability to open scenes even if a node type was removed (will try to guess the closest type).
-Removed deprecated node types.
-=-=-=-=-=-=-=-=-=-=-
-Fixes to Collada Exporter (avoid crash situtions)
-Fixed to Collada Importer (Fixed Animation Optimizer Bugs)
-Fixes to RigidBody/RigidBody2D body_enter/body_exit, was buggy
-Fixed ability for RigidBody/RigidBody2D to get contacts reported and bodyin/out in Kinematic mode.
-Added proper trigger support for 3D Physics shapes
-Changed proper value for Z-Offset in OmniLight
-Fixed spot attenuation bug in SpotLight
-Fixed some 3D and 2D spatial soudn bugs related to distance attenuation.
-Fixed bugs in EventPlayer (channels were muted by default)
-Fix in ButtonGroup (get nodes in group are now returned in order)
-Fixed Linear->SRGB Conversion, previous algo sucked, new algo works OK
-Changed SRGB->Linear conversion to use hardware if supported, improves texture quality a lot
-Fixed options for Y-Fov and X-Fov in camera, should be more intuitive.
-Fixed bugs related to viewports and transparency
Huge Amount of New Stuff:
-=-=-=-=-=-=-=-==-=-=-=-
-Ability to manually advance an AnimationPlayer that is inactive (with advance() function)
-More work in WinRT platform
-Added XY normalmap support, imports on this format by default. Reduces normlmap size and enables much nice compression using LATC
-Added Anisotropic filter support to textures, can be specified on import
-Added support for Non-Square, Isometric and Hexagonal tilemaps in TileMap.
-Added Isometric Dungeon demo.
-Added simple hexagonal map demo.
-Added Truck-Town demo. Shows how most types of joints and vehicles are used. Please somebody make a nicer town, this one is too hardcore.
-Added an Object-Picking API to both RigidBody and Area! (and relevant demo)
-=-=-=-=-=-=-=-=-=-=-=-=-=
-Begin work on Navigation Meshes (simple pathfinding for now, will improve soon)
-More doc on theme overriding
-Upgraded OpenSSL to version without bugs
-Misc bugfixes
-=-=-=-=-=-=-=-=-=-=-=-=-=-=
-Auto indenter in code editor, this makes it much easier to paste external code.
-Zoom in 2D viewport now uses the mouse pointer as reference.
-Obscure hack to see where code/line of GDScript in C++ backtrace.
-Fixed a bug where keys would get stuck on X11 if pressed simultaneously
-Added Api on IP singleton to request local IPs.
-Premultiplied alpha support when importing texture, editing PNGs and as a blend mode.
