## The main features in detail of Cocos2d-x v3.13
2015-11-06 18:38:09 +08:00
2016-08-04 09:48:55 +08:00
### Add VR plugin
2015-11-06 18:38:09 +08:00
2016-08-04 09:48:55 +08:00
TBD: add link of PG
2016-05-04 11:54:38 +08:00
2016-08-04 09:48:55 +08:00
### Support ETC1 alpha channel
2016-05-04 11:54:38 +08:00
2016-08-04 09:48:55 +08:00
Thanks [halx99 ](https://github.com/halx99 )'s contribution, now cocos2d-x supports ETC1 alpha channel by default.
2016-05-04 11:54:38 +08:00
2016-08-04 09:48:55 +08:00
If want to use ETC1 alpha chaneel, you should put `xxx.pkm` and `xxx.pkm@alpha` in the same folder, and use it like this:
2016-05-16 14:01:55 +08:00
2016-08-04 09:48:55 +08:00
```c++
auto sprite = Sprite::create("xxx.pkm");
```
`xxx.pkm@alpha` is the resource for alpha channel. `@alpha` subfix is required by engine to load alpha texture automatically.
More detail usage can refer to the implementation of `Sprite1ETC1Alpha` in `tests/cpp-tests/Classes/SpriteTest/SpriteTest.cpp` .

### AudioEngine performance for Android 4.2+
2016-06-28 17:21:43 +08:00
2016-08-04 09:48:55 +08:00
AudioEngine uses [OpenSL ES ](https://developer.android.com/ndk/guides/audio/opensl-for-android.html ) on Android, and it supports decoding audio source file to PCM data in codes since Android 4.2. Now AudioEngine uses this feature to fix the performance issue. The performane is the same as before if running on Android 4.1 or lower version.
2016-06-28 17:21:43 +08:00
2016-08-04 09:48:55 +08:00
### Android arm-64 support
Now we provide arm-64 bit 3rd party libraries, which means can build 64-bit apps on Android. You can use the command to build 64-bit apps:
```
cocos run -p android --app-abi arm64-v8a
```
2016-06-28 17:21:43 +08:00
2016-08-17 15:40:10 +08:00
### Switch to use gcc 4.9 on Android
2016-05-16 14:01:55 +08:00
2016-08-04 09:48:55 +08:00
cocos2d-x switch to use clang in `v3.12` , but developers reported [some crash issue ](https://github.com/cocos2d/cocos2d-x/issues/16244 ) that caused by using `clang+gnustl_static` , so we switch to use gcc 4.9. We will change to use `clang+c++_static` when `c++_static` is stable.
2016-07-06 14:35:15 +08:00
2016-08-04 09:48:55 +08:00
### Upgrade CURL to 7.50.0
2016-07-06 22:15:56 +08:00
2016-08-04 09:48:55 +08:00
Because CURL has [a bug about connect to IPV4 numerical IP address in NAT64 environment ](https://github.com/curl/curl/issues/863 ), and it is fixed in v7.50.0, so we upgrade to this version when v7.50.0 is released.
