+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.
+
+0.7 [2008-06-23]
+ - LOCAL DATABASE CHANGE: The addition of subfile incrementals has
+ requires an extension to the local database. The upgrade script
+ contrib/upgrade0.7-localdb.sql should be run prior to running
+ backups with this version.
+ - Name change: the system is now known as Cumulus (replacing the old
+ name of "LBS"). Some traces of the old name still remain.
+ - Initial support for direct backups to remote storage. A sample
+ script is provided for backing up to Amazon S3. Other scripts
+ should be simple to write. The interface should not yet be
+ considered stable, and may change in a future release.
+ - Support for efficient subfile incremental backups. Changes to a
+ small portion of a file do not require re-uploading substantially
+ all of the file, even in cases where there is an insertion or
+ deletion that shifts most of the file contents.
+ - Allow selected files/directories to be restored, not simply an
+ entire snapshot. Additionally, restore files in an order that
+ should optimize performance (restore files based on how they are
+ grouped into segments, instead of lexicographic order).
+ Currently, the implementation of these changes requires that all
+ metadata be loaded into memory when the restore tool runs, so it
+ is more memory-intensive than the old version. This may be fixed
+ in a future version; in the meantime, if the current restore tool
+ requires too much memory, try the old restore tool or the
+ restore.pl script.
+ - Add a verbose ("-v") flag. By default, files will not be listed
+ as they are backed up. The old behavior can be turned back on
+ with -v.
