dialog for bad connections. (Bug #18361685)
* The agent.sh/agent.bat help output has been improved. (Bug
* As of this release, the HTTP connection between Agent and Service
Manager has a default timeout of 250 seconds for an attempted
connection and 300 seconds for an established connection. It is
possible to override these values in bootstrap.properties using the
a. http-connect-timeout-ms=N: Where N is the number of milliseconds
to wait before timing-out a HTTP connection attempt.
b. http-socket-timeout-ms=N: Where N is the number of milliseconds

* The Problem Description text of the Binary Log Debug Information
Disabled advisor was updated.
* It was not possible to establish socket connections on x86-based
Solaris systems. (Bug #18711927)
* The y-axis of the Slow Queries graph was incorrectly labelled
Queries/Minutes. As of this release, it is correctly labelled
Queries/Seconds. (Bug #18748920)
* The agent failed to restart if the backlog was corrupted. As of this
release, the agent checks the status of the backlog on startup and,
if the backlog is corrupted, backs it up to a backlog.xxx directory.
The agent logs the error and creates a new backlog, replacing the
corrupted version. (Bug #18680916)
* The Service Manager did not automatically reflect Daylight Savings
Time. (Bug #18384580)
* Agent queries failed if they were run on a MySQL instance with
sql_mode="ONLY_FULL_GROUP_BY". An error was returned.
As of this release, the agent sets the sql_mode to
STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION automatically. The agent
checks to ensure sql_mode is set correctly. If sql_mode is not set,
an error is logged. (Bug #18308706)
* The agent did not read the master-file-info parameter of a
replication slave's configuration. As a result, the slave was not
displayed in the MySQL Enterprise Monitor User Interface. (Bug
