升级实时音视频录制及播放能力

为更高效地连接用户与商家，小程序提供了实时音视频录制及播放组件。符合类目要求的小程序自助开通后，可自建或使用云服务，实现单向、双向甚至多向的音视频功能，如在线授课、远程咨询、视频客服，以及多人会议等。

Optimize basic features

While supporting the merchants with better services, 小程序 optimizes a number of basic features to ensure users get fast access to services.

Developers can divide the 小程序 code into multiple packages, each of which does not exceed 2M, and the total size does not exceed 4M. Therefore, according to the needs of the user, the specified package is downloaded at the appropriate time instead of all, and the opening speed is increased. See《分包加载》

for details.

Developers can write custom components for their own use or open source to other developers, reducing development effort. See《自定义组件》

for details.

The 小程序 page access level limit is relaxed to 10 levels, which is convenient for carrying longer service flows.
