Addon specification (meta.json)

Impacts all add-ons.

Add-ons are defined by a meta.json on their root folder. This file includes basic definitions like version, identifier, name and can hold information about other things like configuration for the frontend and backend part as well.

The schema of meta.json has been reworked and will be replaced by a new .addon.yaml.

Right now, the application takes care of migrating the old meta.json definition to the new .addon.yaml schema whenever an addon is uploaded in case an .addon.yaml cannot be found.
However, in the foreseeable future, all addons are required to provide an .addon.yaml directly. The old meta.json won’t be read anymore.

See the documentation about how to configure add-ons to see any changes from the old to the new format.
