[ubuntu.landing.team at gmail.com]

Dear Ubuntu Quality,

This is an automated report for the ISO manifest-diff check.

We have noticed that the following high-impact packages have changed
on the following images:

 * ubuntu/focal/daily-live/amd64 from 20200205 to 20200206
   [http://cdimage.ubuntu.com//ubuntu/daily-live//20200206/focal-desktop-amd64.iso]:
libglx-mesa0:amd64
netplan.io
network-manager


Please test the affected images with the high-risk packages in mind to
ensure that no accidental regressions have been introduced.

Thank you.
