Application Package Updates

For developers, updating an application package first requires modifying the versionCode field in the app.json5 configuration file. After packaging with DevEco Studio, the update is released on the app market, following the same process as the initial release. For end users, after a new version is released, the application package can be updated through the following methods:

• Update via the app market: The app market notifies users about the availability of a new version, and users can proceed to upgrade via the app market (client).
