I upgraded to the latest release, today Sept 11, from the previous release using the automatic upgrade button.
Upgrade completed but after a restart the image no longer fills the 840x480 waveshare LCD. It looks like 640x480 with the right 1/4 of the screen blank, although the touch screen thinks everything is normal.
Wiped and started new install, same thing. Even the volumio splash screen during boot and shutdown is no longer in the centre, but shifted left.
The previous version 2.5xx it just worked properly after installing the plugin.
