+2.0 (hikitsuboshi) 2007/11/xx
+ * Version 2.0
+
+ * Incompatibility since pgpool-II 1.x
+ - the default value for ignore_leading_white_space is now
+ true(Yoshiyuki)
+
+ * General
+ - Allow to reload pgpool.conf(Yoshiyuki)
+ - The paraser is now compatible with PostgreSQL 8.3(Yoshiyuki)
+ - Add new directive "failover_command" to specify command when
+ a node is detached(Yoshiyuki)
+ - Add new directive "client_idle_limit" to specify the time out since
+ the last command is arrived from a client(Tatsuo)
+
+ * Replication
+ - Always start a new transaction even if the query is not in
+ an explicit transaction to enhance the reliabilty of
+ replication(Yoshiyuki)
+ - Enhance the performance of replication for write
+ queries. Now the worst case is 1/2 compared with single DB
+ node regardless the number of DB nodes. Previous release
+ tends to degrade according to the numer of DB
+ nodes(Yoshiyuki)
+ - Add "online recovery" which allows to add a DB node and sync
+ with other DB nodes without stopping the pgpool
+ server(Yoshiyuki)
+ - Abort a transaction if INSERT, UPDATE and DELETE reports
+ different number of result rows(Yoshiyuki)
+
+ x=# update t set a = a + 1;
+ ERROR: pgpool detected difference of the number of update tuples
+ HINT: check data consistency between master and other db node
+
+ - If the results from DB nodes do not match, select the
+ possible correct result by "decide by majority". Previous
+ release always trust the result of the master DB
+ node(Yoshiyuki)
+ - Allow load balance in V2 frontend/backend protocol(Yoshiyuki)
+
+ * Parallel query
+ - Allow "partial replication" to enhance the performance of
+ the parallel query(Yoshiharu)
+
1.3 (sohiboshi) 2007/10/23
* Version 1.3
* Add new "authentication_timeout" directive, being the default
