+New Catalog format :
+--------------------
+
+This BETA release of Bacula uses a new catalog format. We provide a set of
+script that permit to convert a 2.4.x (version 10) catalog to 2.5.x (version
+11). If you are using already a 2.5 version, you need to drop the JobHistory
+table before upgrading your catalog (if you are using the new "long term
+statistics" module, you can upgrade this table like with the Job table, see
+upgrade_<database>_table script).
+
+The upgrade operation will convert an essential field of the File table, and
+this operation will take TIME and will DOUBLE THE SIZE of your
+catalog temporarily. Depending on your catalog backend, you won't be able to run jobs
+during this period. For example, a 3 million files catalog will take 2mins to
+upgrade on a normal machine. Don't forget to backup it before executing the
+script.
