    Release Notes: This version contains some new features, many improvements of existing features, and several bug fixes. Support for resuming snapshot creation after restart has been added and snapshot removal is deferred until at least one current snapshot exists. The internal handling of the various hooks has been simplified and many error messages have been clarified. On SIGHUP, dss now writes its configuration and internal state to the log file.

      Release Notes: You can now specify pre-rm/post-rm-hooks that are executed whenever a snapshot is deleted. This release adds better compatibility with rsync 3.0, and avoids busy loops when automatically restarting the rsync process.

        Release Notes: This release includes the reason why a snapshot gets removed in the log message. It will never remove the snapshot that is currently being created. It will really pass the full path to the last complete snapshot in the post_create_hook.

          Release Notes: This release prevents busy loops on rsync exit code 13. It ignores any snapshot directory with creation time > completion time. It opens /dev/null for reading and writing when executing rsync. It shows human readable snapshot creation duration when listing snapshots. It restarts the rsync process if it returned with exit code 13.
