Hi !
a lot of users were affected by
https://tails.boum.org/news/version_3.0/#known-issues
we've got a few reports of users having trouble with nividia (mostly
geforce 970) workarounded by adding nouveau.modeset=0 (likely #11831,
but they didn't seem affected with tails 2.*)
2 users affected by
https://labs.riseup.net/code/issues/12543 were asked
to provide the info needed
a few users having trouble with dual monitors (#12730)
2 users reported that virtualbox shared folders does not work anymore #12724
and several users reported that installing by cloning "didn't worked"
(the window shut down and tails is not installed), apparently on devices
made with UUI. I lack information so I'll try to reproduce before
opening a ticket
and a user reported that with firefox 55, downloading the IOS with the
add-on doesn't work due to a certificate mismatch (I still need to try
to reproduce before opening a ticket.
I think that's all,
cheers.
