The Update Center is the place for keeping Sonar platform up to date. It allows to:
- List already installed plugins
- Check and install plugins updates
- List available plugins and install desired ones
- Check Sonar platform updates
To take effect, most actions taken in the Update Center (updating a plugin...) will require Sonar to be restarted. The Update Center is only accessible to administrator through "Configuration" service.
