Can not be used in MuseScore 3, while it works in MuseScore 2

Even if the other plugins show, they don't work. The TempoChanges plugin has not yet been adopted to MuseScore 3, and that because it currently isn't really worthwile, the 3.0 Plugin fremawork is just badly broken.
See #280740: [Feedback form] Plugins don't work (the list of requests)

I went into the plugin creator and the error is it cant find version 1.0 on my system. I altered this to 2.0 and to last know version and then 3.0 and I got the app to work and show in my list of plugins but it does work. Error report is as follows:

The best you can expect from running any plugin in version 3 at the moment is error messages. Keep an eye open for plugins to be fixed in the not to distant future.

TempoChanges has now been ported to MuseScore 3.
