mythplugins problem

Hello all, I update my backend and frontend machines this morning, and
now I can not run any mythplugins (music, gallery and news)

I am on testing. It says that the plugins are not compatible with the
mythtv installed libraries.

Is it possible to revert the update and go to the old (1 week) versions?

Thanks for your help, best regards.
