The landing team is now aware and should be able to help going through
that process. We are pending the announcement of the QA people assigned
doing the testing of 2. and 3. (I think they will be announced in that

CI Train spreadsheet [1] now support that workflow:
* you will notice a new column next to "ready" (on the left before the
last visible one) entitled "QA sign off needed".
-> set it to No (default) if your landing falling into case 1.
-> set it to Yes for landing falling into cases 2. and 3.
Please try to review the current landing in flight and assign them to
the right category before getting your change ready to land. The landing
team is going to help in that transition and assess with you on those
status (especially during the assignement and publication phases). Think
about markin as well in the comment field if your landing is a big or
small feature for you. You are always welcomed to discuss on
#ubuntu-ci-eng on freenode with us.

* Every silo sheet (like in [2]) now contains a "QA sign off" additional
field. This field only has an effect at the global landing status if the
previous column is set to Yes. The QA team will be the one changing that
status once the landing is signed off.

* The global status (ready for publication) will take into account if:
- the lander has done the testing (same field than in the past)
- QA signed off for it; the pending spreadsheet reflects to QA the silos
that are needs and are ready for QA to tests in the global status field.
This only appears once the lander has done first the silo testing.
- if everything goes well, then a "you can publish the package" appears
for the LT to publish the packages to the distribution.

Do not hesitate to ask us if you have any questions/concerns about this
process modification and let's all work together to get a rocking Touch
