 ==== 9 Upgrade notes for 4.4.0 ==== ==== 9 Upgrade notes for 4.4.0 ====
  
-​<note important>​Zabbix 4.4.0 is not released yet.</​note>​+These notes are for upgrading from Zabbix 4.2.x to Zabbix 4.4.0. ​All notes are grouped into:
  
-=== Changed host export format ===+  * ''​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
  
-The format of host and template export has been changed ​in the way how triggers are exportedPreviously all triggers were listed after the host information. Now, to achieve better readabilitytriggers that are based on one host item only are listed within tags of the respective host item.+It is possible to upgrade to Zabbix 4.4.0 from versions before Zabbix 4.2.0. See the [[:​manual/​installation/​upgrade|upgrade procedure]] section for all relevant information about upgrading from previous Zabbix versions. 
 + 
 +==== Critical ==== 
 + 
 +=== Jabber, Ez Texting media types removed === 
 + 
 +Jabber ​and Ez Texting [[:​manual/​config/​notifications/​media|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 protocol changed === 
 + 
 +[[:​manual/​appendix/​install/​real_time_export|Real-time export]] now also includes host names, not only the visible host namesNote that the real-time [[:​manual/​appendix/​protocols/​real_time_export|export protocol]] has been changed with host name information ​now an objectrather than a string/​array. 
 + 
 +==== Informational ==== 
 + 
 +=== Screen element removed from screens === 
 + 
 +Zabbix screens no longer support the possibility ​to display another screen as a screen element. After the upgradeall screen cells containing another screen will be empty. 
 + 
 +=== Linked template selection === 
 + 
 +The multi-select field for selecting linked templates has been removed from host/template configuration forms. To link templates, click on //Add// and then select templates in the popup window. 
 + 
 +=== Changed host export format ===
  
-Note also how the expression ​of the triggers does not reference the host or itembut only the function (''​{last()}<>​0''​ in the example):+The format ​of host/template export in XML/JSON has been changed. For more detailssee [[:​manual/​introduction/​whatsnew440#​changed_host_export_format|What's new in 4.4.0]].
