Since version 1.3.3 OctoPrint supports centralized plugin notices that can be displayed to users that have specific plugins/plugin versions installed. This is used by the official plugin repository to notify about issues or changes in the plugins that require action of the user.

Displaying the notices is implemented by the bundled Plugin Manager inside OctoPrint.

The notices are hosted here on as a JSON file and currently contain the following entries:
