Ubuntu Kernel Team - Weekly Newsletter, 2017-11-07

October 24 through November 06

##Development (18.04)##
Every 6 months the Ubuntu Kernel Team is tasked to pick the kernel to be
used in the next release. This is a difficult thing to do because we
don't definitively know what will be going into the upstream kernel over
the next 6 months nor the quality of that kernel. We look at the Ubuntu
release schedule and how that will line up with the upstream kernel
releases. We talk to hardware vendors about when they will be landing
their changes upstream and what they would prefer as the Ubuntu kernel
version. We talk to major cloud vendors and ask them what they would
like.  We speak to large consumers of Ubuntu to solicit their opinion. 
We look at what will be the next upstream stable kernel. We get input
from members of the Canonical product strategy team. Taking all of that
into account we are tentatively planning to converge on 4.15 for the
Bionic Beaver 18.04 LTS release.

On the road to 18.04 we have a 4.14 based kernel in the kernel team's
unstable ppa.
