Until RC1 we used Xubuntu 12.04.1 base iso and during *all* our builds 
we used "apt-get upgrade".
This means all updates until the day we built RC1 are included (except 
kernel updates that were kept back to protect chroot environment)
The new 12.04.2 base iso brings in updates that were released the last 
couple of days (Qt4, openJDK updates and a new kernel)
The new kernel (3.2.0-37) brings support for Secure Boot and I seriously 
doubt that it would affect any software of our stack.
OpenJDK update brings in the last *very critical* java patches that so 
much noise was made around the internet the last weeks. My opinion is 
that this is a serious security update and we should ship with it.
Regarding Qt4 updates, small part of our stack is built on Qt and we can 
test those applications to check that they are not affected.

Regarding hardware, I am not sure we ever tested on specific hardware. I 
feel that we always trust Ubuntu on this area. Why should this change now?

I think this is covered above.

I understand that we lack on the testing side, and yes we need more 
testers to make all the quality checks needed.

I feel that since testing was only done so far by a small number of 
users, it would not be hard to run one more round of testing before 
release, but I really want to hear everybody’s opinion on this.
