## A.193.1. Bug fixes

- Fix to sort startup packet's parameters sent by client. (bug 444)(Takuma Hoshiai)

  If order of startup packet's parameters differ between cached connection pools and connection request, didn't use connection pool ,and created new connection pool.

- Fix segmentation fault occurs when a certain Bind message is sent in native replication mode. (bug 443)(Bo Peng)

  If the number of parameter format codes is specified to one, but the number of the original query's parameter is zero, `bind_rewrite_timestamp()` will call `memcpy` with a negative value. This causes segmentation fault.

  Patch is provided by Yugo Nagata.

- Fix a query passed to relcache so that it uses schema qualified table name. (Tatsuo Ishii)

- Fix query cache invalidation bug. (Tatsuo Ishii)

- Fix memory leak in extended query + query cache enabled. (Tatsuo Ishii)
