+ - Metadata is shared between snapshots where possible. The
+ --full-metadata option can be used to disable this (completely
+ writing out all metadata with the new snapshot).
+ - Add an "intent" field to snapshots, which specifies informally how
+ long a snapshot is intended to be kept. For example, 1 can be
+ used for daily snapshots, and 7 for weekly snapshots. Segment
+ cleaning is now partly guided by intent values, but tuning of the
+ cleaning algorithms is not yet finished.
