[MySQL][Spider][VP][Other]Spider-2.24 VP-0.13 released

I'm pleased to announce the release of Spider storage engine version 2.24(beta) and Vertical Partitioning storage engine version 0.13(beta).
Spider is a Storage Engine for database sharding.
http://spiderformysql.com/
Vertical Partitioning is a Storage Engine for vertical partitioning for a table.
http://launchpad.net/vpformysql

The main changes in this version are following.
Spider
- MySQL 5.5 support.
- handlersocket support.
  You can use handlersocket through Spider table that called by handlersocket. It means handlersocket can access to sharded databases. Currently, handlersocket support only Linux.
  Set "spider_use_hs_read=1" and "spider_use_hs_write=1" for activating this feature.
  Added following parameters to bundled handlersocket.
  #1 handlersocket_support_merge_table
    Please set this parameter to 1, if you want to use merge_myisam and vp tables through handlersocket.
  #2 handlersocket_direct_update_mode
    Improvement performance for a lot of rows updating. Currentry, this parameter works only for Spider table(except partitioned Spider table). I will add a direct update feature for partitioned Spider table at next release.
    There are following modes.
    0:Normal
    1:direct update mode 1
      This mode can write binary logs on local server at direct updating.
    2:direct update mode 2
      This mode cannot write binary logs on local server at direct updating, but this mode is the fastest. (This mode can write binary logs on remote server)
  #3 handlersocket_unlimited_boundary
    If limit value is more than this parameter, limit value means unlimited.
- Support fulltext search.
  Except partitioned Spider table. I will add a fulltext search feature for partitioned Spider table at next release.
- It's available to set monitoring_node for per table, per link_id and per pertition to mysql.spider_link_mon_servers.
- Add table parameter "hs_read_port", "hs_write_port", "use_handler", "use_hs_read", "use_hs_write", "hs_read_socket" and "hs_write_socket".
- Add server parameter "spider_use_handler", "spider_use_hs_read", "spider_use_hs_write", "spider_hs_r_conn_recycle_mode", "spider_hs_r_conn_recycle_strict", "spider_hs_w_conn_recycle_mode" and "spider_hs_w_conn_recycle_strict".
- Add value of 3 to "auto_increment_mode"(table parameter) and "spider_auto_increment_mode"(server parameter).

Vertical Partitioning
- MySQL 5.5 support.
- Support full text search.
  Except partitioned VP table. I will add a fulltext search feature for partitioned VP table at next release.
