+0.6
+ - SNAPSHOT FORMAT CHANGE: A few minor tweaks have been made to the
+ snapshot format. There is nothing substantial--this is primarily
+ a cleaning up of the format before use becomes more widespread.
+ Updated tools will be needed to properly understand the new
+ snapshots. Tools will continue to be able to read the old
+ snapshot format.
+ - LOCAL DATABASE CHANGE: The local database has been changed so that
+ segment utilization data for past snapshots is stored more
+ efficiently. The script in contrib/upgrade0.6-localdb.sql must be
+ run on a database to upgrade it prior to running backups with the
+ new tool.
+ - The statcache implementation has been reworked, and the format
+ changed. The first backup will run more slowly since the old
+ statcache data will be ignored. New statcache data will be
+ written to statcache2. The old statcache file can be deleted.
+
+0.5.1 [2007-11-13]
+ - Have the lbs-util tool check the version number when reading a
+ snapshot, and signal an error if the format is not recognized.
+ - Include a sample script, contrib/parity-gen, for creating
+ RAID-like parity sets to recover from some segment corruption.
+ The par2 command (http://parchive.sourceforge.net/) is used to
+ actually generate the parity sets; the parity-gen script simply
+ automates maintaining the parity sets.
+
+0.5 [2007-10-16]
+ - Much improved Python interface for accessing and manipulating LBS
+ archives and local database information. The interface should not
+ yet be considered completely stable.
+ - Python implementation of lbs-util now includes most of the
+ features of the Perl implementation, plus some other new features.
+ The Perl library and utility are deprecated and have been removed
+ from this release.
+ - Preliminary snapshot restore support in lbs-util. This is still
+ not yet extensively tested.

0.4 [2007-08-24]
- Documentation improvements: a getting started README, and a
description of some of the implementation details.
