Changelog v4.5.0:

#Added: the plugin will now inform you if the latest implementation is used and if so, for what version it was last tested.

#Changed: the warning messages about the lack of a valid implementation was more or less replaced by the above info message.

The plugin already tried to use the default implementation if no valid implementation was found. Therefore I think these changes give some clarity over what is actually happening. In addition future versions will now not be "unvalid" so to speak but rather untested (hence the new info message informing you of the last tested version) because the later versions will very likely work except for new attributes or block types.

I hope this gives more transparency.
