Size

Modularization: automatically reduce the size by c++ linker, and simply to only 2 libraries in cocos2d-x, one for c++, another for Lua

Take lua-empty-test as example:

libluaemptytest.so is 9.5M in v3.2
libluaemptytest.so is 5.5M in v3.3

Performance

Added ClippingRectangeNode, which is more efficient for rectangle clipping
Renderer: added triangle command
Cocos Studio Reader: use Flat Buffer for data format

Usability

Added a consistent way to set GL context attributes for all platforms
Node: schedule/unschedule with lambda function
Added c++11 random support in cocos2d::random(a,b)
RenderTexture: add a callback function for saveToFile()`
DrawNode: added as many functions as DrawPrimitive, while DrawPrimitive is deprecated
add setKeepScreenOn() on iOS and Android

Enhancements

Infrastructure

Added new audio engine on iOS and Android
Added AssetsManagerEx for hot-updates
Tilemap: supported staggered tile map
Primitive: Support Points, Lines, and Triangles for rendering
SpriteFrameCache: support loading from plist file content data

UI

Added Application::openURL()
Added WebView on iOS and Android
Added ui::Scale9Sprite

3D

3D light: directional light, point light, spot light and ambient light
BillBoard
Camera
Reskin
Attachment
Better support for FBX, and new fbx-conv
AABB, OBB and Ray

Following gif is the effect of Light. You can run cpp-tests to check other modules’ effect.

3rd party libraries

Facebook SDK integrated in plugin on iOS and Android
Updated Spine runtime to v2.0.18

Platforms

Android: Support Android ARM 64 bit, tested on Nexus 9
WP8:
- add win8.1 univeral app support
- update to Visual Studio 2013 with update 3 to use Cocos2dShaderCompiler

Documentation

3D sample

我们还创建了一个 3D 实例：FantasyWarrior3D, 用来演示如何通过 cocos2d-x 开发 3d 应用。

The game runs smoothly on old Android phone with single core 1G HZ CPU.

而 2.2.6 版本只要是增加 64 位 iOS 支持，下载地址：http://www.cocos2d-x.org/filedown/cocos2d-x-2.2.6.zip
