Zabbix agent 2 now allows to override named session parameters by specifying new values in the item key parameters. Previously, users had to select if they prefer to provide connection string values in a named session or in an item key. If a named session has been used, related item key parameters had to be empty. Now, if using named sessions, only the first parameter (usually, a URI) has to be specified in the named session, whereas other parameters can be defined either in the named session or in the item key.
