Welcome in 2017, dear changelog reader! That year should bring the long-awaited OpenGL ES 3.0 compatible renderer with state-of-the-art rendering techniques tuned to work as low as middle end handheld devices - without compromising with the possibilities given for higher end desktop games of course. Great times ahead for the Godot community and the gamers that will play our games! (cherry picked from commit c7bc44d5ad9aae4902280012f7654e2318cd910e)

Making Godot Easier to Use.. -=-=-=-=-=-=-=-=-=-=-=-=-=-= -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.

Ability to keep collisionshapes and collisionpolygons when running the game. Works for 2D and 3D These are still just helpers in case you want to animate them or access them directly. Modifying the real shapes is still done via CollisionObject and CollisionObject2D APIs But an API was added so you can query which shapes from CollisionObject correspond to which CollisionShape.

-Added google play services (needed for some stuff) -Added new screen resizing options, stretch_2d is removed, new much more flexible ones. -Fixed bug in viewport (can create more instances in 3d-in-2d demo now) -Can set android permissions and screen sizes manually in the export settings -Changed export templates extension to .tpz (too many people unzipped the manually..) -File dialog now ensures that the proper extension is used (will not allow to save without it) -Fixed bug that made collision exceptions not work in 2D

Bring that Whole New World to the Old Continent too Applies the clang-format style to the 2.1 branch as done for master in 5dbf1809c6e3e905b94b8764e99491e608122261.

void set_material(const Ref<CanvasItemMaterial> &p_material);
support for 2D shadow casters Added support for 2D shadow casters. *DANGER* Shaders in CanvasItem CHANGED, if you are using shader in a CanvasItem and pull this, you will lose them. Shaders now work through a 2D material system similar to 3D. If you don't want to lose the 2D shader code, save the shader as a .shd, then create a material in CanvasItem and re-assign the shader.

-fixed issue with shader not being reset on layers, closes #1199 -ability for shader to use parent shader and params, closes #1198

Ability to keep collisionshapes and collisionpolygons when running the game. Works for 2D and 3D These are still just helpers in case you want to animate them or access them directly. Modifying the real shapes is still done via CollisionObject and CollisionObject2D APIs But an API was added so you can query which shapes from CollisionObject correspond to which CollisionShape. Have Fun!
