These notes are for upgrading from Zabbix 4.2.x to Zabbix 4.4.0. All notes are grouped into:
Critical- the most critical information related to the upgrade process and the changes in Zabbix functionality
Informational- all remaining information describing the changes in Zabbix functionality
It is possible to upgrade to Zabbix 4.4.0 from versions before Zabbix 4.2.0. See the upgrade procedure section for all relevant information about upgrading from previous Zabbix versions.
Jabber and Ez Texting media types for delivering notifications have been removed.
During the upgrade these media types, if present in your installation, will be transformed to a script media type with all relevant parameters preserved. However, notifications via Jabber and Ez Texting will not work any more.
Real-time export now also includes host names, not only the visible host names. Note that the real-time export protocol has been changed with host name information now an object, rather than a string/array.
Zabbix screens no longer support the possibility to display another screen as a screen element. After the upgrade, all screen cells containing another screen will be empty.
The format of host/template export in XML/JSON has been changed. For more details, see What's new in 4.4.0.
Realtime fields have been split from the
items table into a new table called
item_rtdata. See also What's new in 4.4.0.
