+Added in version 8.0.5, the new ``M'' option letter for the Accurate directive
+in the FileSet Options block, which allows comparing the modification time and/or
+creation time against the last backup timestamp. This is in contrast to the
+existing options letters ``m'' and/or ``c'', mtime and ctime, which are checked
+against the stored catalog values, that could vary accross different machines
+when using the BaseJob feature.
+
+The advantage of the new ``M'' option letter for Jobs that refer to BaseJobs is
+that it will backup files based on the last backup time, which is more useful,
+because the mtime/ctime timestamps may differ on various Clients, causing
+unnecessary files to be backed up.
