We have two cases that are not properly handled right now:
- Plugins that are still compatible with Picard, but don't work anymore for other reasons (e.g. the last.fm plugins broke due to last.fm API changes)
- Plugins that are listed, but are only compatible with the development version (the fanarttv plugin is a current example)
For 1. the correct solution would be to either fix them or remove them completely. For 2. ideally we don't list the plugins here at all but a compatible version, if available. There was already some discussion about this somewhere, maybe by providing a plugin development branch or similar. But again nobody finds the time to tackle this
Listing the compatible Picard versions still would make sense on the plugin download page, especially for people not using the latest Picard for some reason.
