Upgrade process

To complete a successful Zabbix server upgrade on MySQL/MariaDB, you may require to set GLOBAL log_bin_trust_function_creators = 1 in MySQL if binary logging is enabled, there are no superuser privileges and log_bin_trust_function_creators = 1 is not set in MySQL configuration file.

To set the variable using the MySQL console, run:

mysql> SET GLOBAL log_bin_trust_function_creators = 1;

Once the upgrade has been successfully completed, this option can be disabled:

mysql> SET GLOBAL log_bin_trust_function_creators = 0;

Breaking changes

Oracle DB dropped

The support for Oracle as a backend database has been completely removed.

Items turn unsupported with no pollers configured

A check for poller has been added when an item is added to configuration cache and when item type changes. This check has been added for agent, SNMP agent, HTTP agent, browser, script, JMX monitoring, ODBC monitor, and IPMI items.

If no pollers are configured, the items will turn unsupported instead of being simply ignored. This change does not affect item behavior when executed manually ("Test item") or script execution.
