The plugin does not support any additional parts beyond the standard A/B parts. I can't tell you what the upgrade plans are because I don't know.

I doubt if any upgrade would be applied to earlier plugin versions. My understanding is the plugin uses a bridge application to communicate between the plugin and the main Band-in-a-Box program. The plugin tells the main Band-in-a-Box program what is needed, the main Band-in-a-Box program actually does the work then sends the completed work to the plugin. Both the plugin and the bridge would need to understand how to handle part extensions. Since there is a new version of the plugin released each year I doubt if a current year plugin and bridge can properly communicate with an earlier version of the main program.
