+ * mod_dbd: Key the storage of prepared statements on the hex string
+ value of server_rec, rather than the server name, as the server name
+ may change (eg when the server name is set) at any time, causing
+ weird behaviour in modules dependent on mod_dbd.
+ Trunk: http://svn.apache.org/viewvc?view=rev&revision=466641

+
+ * mod_authn_dbd: Export any additional columns queried in the SQL select
+ into the environment with the name AUTHENTICATE_<COLUMN>. This brings
+ mod_authn_dbd behaviour in line with mod_authnz_ldap.
