Having issues with i2c nodes since yesterday following the application of the node-red-contrib-i2c 0.7.4 update.

bus addresses are invalid.

I haven't changed anything with the bus address in any of the nodes (they remain at 1).  
the individual addresses are fed through messages.... but of course I haven't changed that either. The only change is upgrade of Node-Red to 1.26 and the upgrade of the contrib-i2c node.
