- 8. Routers now support multiple "condition" tests, IF each router yields
-    a string which the bool{} operator recognises.  Note that this is a departure
-    from normal Router "condition" truth, requiring the stricter standard of
-    "true" that ACLS use.  This might be relaxed in a future release if there
-    is sufficient demand.
-    When debugging, bear in mind that these are internally wrapped up into
-    a longer, more complicated, string.  There's a reason that the bool{}
-    logic is a dependency.
+ 8. There is a new expansion operator, bool_lax{}.  Where bool{} uses the ACL
+    condition logic to determine truth/failure and will fail to expand many
+    strings, bool_lax{} uses the router condition logic, where most strings
+    do evaluate true.
+    Note: bool{00} is false, bool_lax{00} is true.
