Oracle-native TNS name support has been added to the Oracle plugin in Zabbix agent 2. The TNS key or TNS value can be specified on the level of item key parameters or the plugin configuration (for named session or default parameters).
TNS name support allows connection description in a clustered DB environment with a single Zabbix host. For more information, see the Oracle plugin readme.
The maximum value for the timeout
parameter of the zabbix_get and zabbix_js command-line utilities has been increased to 600 seconds.
The maximum supported version for MariaDB is now 12.0.X.
