Hello,

Zeljko and I will upgrade Jenkins on Monday Sept 7th at 8:00am UTC (10:00am CET).

There will be roughly half an hour downtime. Zuul will keep queueing the changes and trigger the jobs whenever Jenkins comes back up.

In case of crazy side effect, we will revert back to the current version.

Expected downtime is half an hour but I scheduled a two hours maintenance window.
