## 渲染后端

- Metal: macOS, iOS
- OpenGL 3.3+: Linux, macOS, Win32
- OpenGL ES 2.0+: Android
- OpenGL ES 3.0+: iOS
- ANGLE GLES 3.0+: Win32, WinUWP
- WebGL 2.0(Open GLES 3.0): WASM (experimental)

## 新的媒体播放器

新的媒体播放器`ui::MediaPlayer`(原命: `ui::VideoPlayer`) 将视频渲染为纹理，使得游戏对视频渲染控制更加灵活，就像普通UI一样，而无需考虑层级问题。这得益于重新升级的跨平台`MediaEngine`, 灵感来自微软的媒体基础库(Microsoft Media Foundation): `IMFMediaEngine`，目前已支持axmol引擎支持的所有平台。

## 构建

请查看: [Dev setup instructions](docs/DevSetup.md).
  
### 主要特性:

* WebAssembly支持（实验性的）by @nowasm
* Windows UWP 支持，请参考: https://github.com/axmolengine/axmol/pull/1108
* 增加tvos支持
* 增强Windows下工作流，支持链接引擎预编译库, 用法请查看: [windows workflow guide](https://github.com/axmolengine/axmol/issues/564)
* Windows 视频播放支持
* Windows x64编译支持
* 基于yasio重构HttpClient以支持并发Http请求，不再需要sendImmidate接口
* 重构AudioEngine, 全平台OpenAL
  * [openal-soft](https://github.com/kcat/openal-soft), pass -DAX_USE_ALSOFT=ON to cmake to force enable it
  * [OpenAL.framework](https://opensource.apple.com/tarballs/OpenAL), if no and ```AX_USE_ALSOFT``` option specified, cmake script will choose it on osx/ios, even through it was mark as deprecated, but still avaiable.
* 重构UserDefault, 全平台基于内存映射文件 [mio](https://github.com/mandreyel/mio), 性能提升百倍
* 模块化所有引擎扩展库, 所有扩展库放到extensions目录下，如cocostudio, spine
* AudioEngine实现wav所有 ```openal-soft``` 支持的封装格式, 例如MS-ADPCM, ADPCM等
* 使用现代化的GL加载器glad代替glew
* 增加google angle渲染后端支持
* C++最低标准要求: C++17/20
* 设置ios下最低目标平台为ios11.0
* 使用更快的xml解析库pugixml代替tinyxml2
* Downloader全平台统一实现，均基于curl
* 全平台统一使用XML SAX解析plist文件, 移除Apple平台的实现
* Spine 3.8支持
* 新增FairyGUI支持
* 新增硬件压缩纹理格式ASTC 4x4/6x6/8x8支持，支持软解
* 新增硬件压缩纹理格式ETC2 RGB/RGBA支持，支持软解
* **ImGui集成，非常方便写游戏内嵌小工具，用法详见[ImGui](extensions/ImGui/README.md)**
* 完整改动列表，请查看[CHANGELOG](CHANGELOG)
