6.3.2. Selecting the upload urgency

The release team have indicated that they expect most uploads to unstable to use urgency=medium. That is, you should choose urgency=medium unless there is some particular reason for the upload to migrate to testing more quickly or slowly (see Updates from unstable). For example, you might select urgency=low if the changes since the last upload are large and might be disruptive in unanticipated ways.
