+<title>Release 1.3 (2013-01-04)</title>
+
+<para>This is primarily a bug fix release.  When this version is first
+run on Linux, it removes any immutable bits from the Nix store and
+increases the schema version of the Nix store.  (The previous release
+removed support for setting the immutable bit; this release clears any
+remaining immutable bits to make certain operations more
+efficient.)</para>

+<para>This release has contributions from Eelco Dolstra and Stuart
