This page provides collective upgrade notes for minor releases of the major Zabbix version.
See also upgrade notes of the major version.
Warning! Upgrading to this version is not recommended due to errors related to graphs and the Zabbix agent 2 MySQL plugin.
The minimum supported version for the cURL PHP extension is now 7.19.4.
Zabbix agent 2 runtime control commands (zabbix_agent2 -R <option>) now write output to stdout (standard output) instead of stderr (standard error). Please update any scripts that rely on previous behavior.
