[MySQL][Spider]Spider storage engine 2.0 released

I'm pleased to announce the release of Spider storage engine version 2.0(beta).
http://spiderformysql.com/
From this time, version 1.x is stable releases, version 2.x is development releases for new features.

The main changes in this version are following.
- Add table parameter "semi_table_lock_connection".
- Add server parameter "spider_semi_table_lock_connection".
  Spider has "spider_semi_trx", "spider_semi_trx_isolation", (for transactional tables like InnoDB) "spider_semi_table_lock" and "semi_table_lock" (for non transactional tables like MyISAM) options for consistent reading at remote servers during executing 1 SQL at local server. But you must use different connections for transactional tables and non transactional tables because "semi_table_lock" causes implicit transaction commit.
  "semi_table_lock_connection" and "spider_semi_table_lock_connection" can use different connection for transactional tables and non transactional tables by checking that "semi_table_lock" is enabled.

Please see "99_change_logs.txt" in the download documents for checking other changes.

Enjoy!
