 * For Linux, the sorting of addresses returned by getaddrinfo now also
   handles rules 3 and 7 from RFC 3484.  Implemented by Ulrich Drepper.
 
+* Allow system admin to configure getaddrinfo with the /etc/gai.conf file.

+
 * New Linux interfaces: splice, tee, sync_file_range, vmsplace.
 
 * New iconv module for MIK.  Contributed by Alexander Shopov.
 
+* For sites with broken group and/or passwd database, the auto-propagate
+  option of nscd can prevent creating ID lookup entries from the results
+  of a name lookup and vice versa.   This usually is no problem but some
+  site might have problems with default behavior.
+  Implemented by Ulrich Drepper.
+
+* Iterating over entire database in NIS and NIS+ can be slow.  With the
+  SETENT_BATCH_READ option in /etc/default/nss a system admin can decide
+  to trade time for memory.  The entire database will be read at once.
