---- 2.0.27 2004/10/XX
+--- 2.0.30 2005/01/03
+
+Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
+instead of LOG_, due to name clash with syslog(3). LOG_ are still
+present. New applications should define YAZ_USE_NEW_LOG=1 - this
+will effectively disable old definitions.
+
+--- 2.0.28 2004/11/09
+
+Added yaz_log_time_format which specifies log format using
+strftime(3).
+
+Added yaz_log_module_level which returns mask for a module. Value
+is non-zero mask a if module is enabled; zero if disabled.
