# release

Weixin Mini Program When reviewing, it will review whether the declaration ofsupportedMaterialsis compliant. The Mini Program will appear only after the corresponding file type opens the entrance to the Mini Program.

Features implemented by Weixin Mini Program will not be approved if they are of low value, including but not limited to:

1. The function after opening Weixin Mini Program has nothing to do with the corresponding material: it just opens its own Mini Program through this entrance, and does not do any processing of the material.
2. Turning on Weixin Mini Program to process material is too simple: simple functions such as simply playing a video or simply viewing a.docx file, for example, that can be achieved through WeChat chat.

Please developers combine their own Weixin Mini Program features and user needs to adapt.
