+# This value should be increased whenever changing the structure of
+# any object that will appear in a type 'map' master file (which
+# contains a working memory image of an RBT database), as loading 
+# an incorrect memory image produces an inconsistent and probably
+# nonfunctional database.  These structures include but are not
+# necessarily limited to dns_masterrawheader, rbtdb_file_header,
+# rbt_file_header, dns_rbtdb, dns_rbt, dns_rbtnode, rdatasetheader.
+#
+# Err on the side of caution: if anything in the RBTDB is changed,
+# bump the value.  Making map files unreadable protects the system
+# from instability; it's a feature not a bug.
+#
+# Whenever releasing a new major release of BIND9, set this value
+# back to 1.0 when releasing the first alpha.  Map files are *never*
+# compatible across major releases.
