+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.
+    - Include an example filter script, lbs-filter-gpg, for encrypting
+      segment data as it is written.
+    - Add support for signed snapshot descriptor files (via the
+      --signature-filter option).  Due to the checksums contained in the
+      snapshot descriptor, the signature covers the entire contents of
+      the snapshot.
+    - Preview release of lbs-util.py, a Python-based program for
+      managing LBS snapshots.  It currently implements a very simple
+      form of automatic segment cleaning, though this isn't much tested.
+    - Improved segment repacking support; after cleaning segments,
+      objects can be written out in different groups based on age.  This
+      may help with long-term segment cleaning efficiency, but probably
+      needs more tuning.

 0.3 [2007-08-10]
     - LOCAL DATABASE CHANGE: A checksums file is now written out along
       with the snapshot descriptor that contains checksums of segments
