[Ubuntu Notifier]

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 20210302 to 20210303
   [http://cdimage.ubuntu.com//focal/daily-live//20210303/focal-desktop-amd64.iso]:
grub-pc
 * ubuntu/hirsute/daily-live/amd64 from 20210302 to 20210303
   [http://cdimage.ubuntu.com///daily-live//20210303/hirsute-desktop-amd64.iso]:
casper


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

Thank you.
