Added four new InnoDB graphs: InnoDB Row Lock Time (the total time spent acquiring row locks), InnoDB Row Lock Time Statistics (the average and maximum time spent acquiring row locks), and InnoDB Row Lock Wait (the number of times a row lock had to be waited for), and InnoDB Redo Log Checkpoint Lag (tracks both flush and checkpoint differences against the maximum log file size).

The bundled MySQL version has been upgraded to version 5.5.21. The previous version was 5.1.56.
Note: On Linux, MySQL Server 5.5.10 and greater depends on the
libaio library being available on the server.
Therefore, this dependency affects the bundled MySQL Server.
Solaris, Windows, and Mac OS X enable AIO functionality by

The "Query Cache Has Sub-Optimal Hit Rate" rule would trigger a critical alert when more than 25% of the cache was free, instead of when more than 25% of the cache was used. (Bug #13921932)
The MySQL Enterprise Backup temporary table
mysql.ibbackup_binlog_marker is now excluded
from the "User Has Rights To Table That Does Not Exist" advisor.
The Installer/Updater would emit a warning when the required
libaio was not detected, but it would
continue with the incomplete installation. It now prompts to
enter the path, and the unattended installer exits with an
The "Excessive Number of Long Running Processes" rule was updated to ignore replication threads, as binlog dump entries are now ignored. (Bug #13841872)

When an agent is used along with MySQL Enterprise Agent Proxy Service, the
LOAD DATA LOCAL INFILE statement could cause
memory exhaustion with large files, due to the entire file/query
being buffered before execution.
The Update script would not update properly if a non-bundled version of MySQL was used previously, and a version configured as localhost or 127.0.0.1. (Bug #13847215)

size is "
query_cache_size = 32M" instead of
query_cache_size = 25% of total RAM."
It was not possible to delete multiple servers within the
