+Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
+instead of LOG_, due to name clash with syslog(3). The new header for
+YAZ log is <yaz/ylog.h>. The old definitions are kept in <yaz/log.h>
+with all old definitions with values kept - so all applications should
+compile as usual. See "Log" chapter in YAZ manual.
+
+--- 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.
+
+* Fixed bug #148: CQL parser may leak. A few prototypes were changed
+in include/yaz/cql.h.
