[Chris Hermansen]

Re-installing QGIS 3.12.2 Bucaresti using apt install after upgrade from 19.10 to 20.04 I received the following warnings coming from the Ubuntu plotly package:

Thanks to upstream for being all over this!

And please pardon my ignorance, but given that this appears to be getting fixed in version 4.6, how will (or will) that make its way back to Ubuntu 20.04?
