Major changes from beta1 to beta2 are:

* Watchdog

     - Fix to read wd_port. (Atsushi Mitani)

       In the previous version some prameters were not reloaded.

     - Add a new parameter: wd_hostname with which means watchdog process
       receives the other pgpools' ones.
       (Atsushi Mitani)

       In the previous version pgpool2_hostname was used for this, but if
       all of pgpool2_hostname in each pgpool-II were 'localhost',
       initializing watchdog and ligechecking didn't work well.

* Bug Fix

    - Fix pool_process_query() bug reported in [pgpool-general: 672].
      (Tatsuo Ishii)

      This is caused by the function waits for primary node which does not
      have pending data, while standbys have pending data.

      [pgpool-general: 672] Transaction never finishes

    - Fix wait_for_query_response() not to send param status to frontend if
      frontend is NULL. (Tatsuo Ishii)

      This could happen while processing reset_query_list and occur crash.

    - Fix bug with treatment of BEGIN TRANSACTION in master/slave mode.
      (Tatsuo Ishii)

      Original complain is [pgpool-general: 714].
      From 3.1, pgpool-II sends BEGIN.. to all DB nodes. Of course we
      cannot send BEGIN TRANSACTION READ WRITE to standby nodes.
      Problem is, we did not check BEGIN WORK ISOLATION LEVEL SERIALIZABLE;
      and sent to standby nodes. Of course this is wrong, since it's not
      allowed to run transactions in serializable mode on standby nodes.

      [pgpool-general: 714] 
      Load Balancing / Streaming Replication / Isolation Level serializable
