Urgency guidelines
low-urgency: update at your own convenience, sometime within our normal monthly update cycle
medium-urgency: may contain an important stability fix, it is better to update sooner rather than later
high-urgency: update as soon as you can, this is a critical update required for Nimbus to function correctly
