-0.7 [??]
+0.11 [???]
+    - SNAPSHOT FORMAT CHANGES:
+        - The object slice syntax has been simplified; backup restores
+          are still possible but rebuilding the local database from
+          snapshots before v0.8 will require translation.
+        - Timestamps encoded into the top-level snapshot file name are
+          now UTC instead of the local time zone.  This should avoid
+          ambiguity and ensure sorted order is chronological order in
+          the face of time zone changes.
+        - The format identifier is now "Format: Cumulus Snapshot v0.nn"
+          instead of "Format: LBS Snapshot v0.nn" (but the updated tools
+          will accept either variation).
+        - Additional checksum algorithms: sha224, sha256 (sha1 is still
+          supported).
+    - LOCAL DATABASE CHANGES:
+        - Segment utilization data (per snapshot) is tracked
+          differently, to allow better segment cleaning decisions.
+    - New, greatly-enhanced file include/exclude filtering language.
+      This is based on the filter language is rsync (though simplified)
+      and allows glob-like patterns.  It also supports filter rules
+      merged at backup-time from files in the file system; this allows,
+      for example, users to control which files in their home
+      directories are included in backups.  See doc/exclude.rst for
+      details.
+    - A new Python-based command-line interface to Cumulus.  Eventually
+      this should be the only command directly invoked by the user; it
+      will automate backup expiration, segment cleaning, backup
+      mirroring, etc.  Configuration options are read from a config file
+      so they can be applied consistently.
+
+0.10 [2012-05-29]
+    - Make a release that packages up various long-existing patches.
+    - Add FTP and SFTP storage backends (from Ralf Schlatterbeck and
+      Albert Dengg).
+    - Various bugfixes.
+
+0.9 [2009-07-28]
+    - Rework storage layer, to make it easier to support local files,
+      S3, and in the future more storage backends.  cumulus-util now
+      permits URLS for specifying storage locations, including s3:// for
+      Amazon S3 storage.
+    - The script-level interface between the main cumulus binary and
+      remote storage has changed.  It should not yet be considered
+      completely finalized.
+    - Add a tool (cumulus-sync) for copying snapshots between storage
+      repositories.
+    - Add a (mostly proof-of-concept) FUSE interface for accessing
+      snapshots.
+    - Implement a basic garbage-collection command for deleting unused
+      segments.  There still needs to be a way to select snapshots to
+      delete (perhaps based on some type of schedule).
+    - Assorted minor bugfixes.
+
+0.8 [2008-08-01]
+    - SNAPSHOT FORMAT CHANGE: The snapshot format has been extended to
+      allow the local database to be partially rebuilt from the contents
+      of the metadata log.  This may be useful for disaster recovery and
+      other scenarios.  The changes are small, but old tools will not
+      read the new backups.
+    - Add the --rebuild-statcache option which will re-read all files
+      instead of depending on the statcache file to be correct.  This
+      will additionally print warnings if a file has changed but would
+      not have been detected as changed based on the statcache, and will
+      add subfile incremental signatures for existing files that do not
+      have them.
