 ==== 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 in problem ​and recovery expression 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 auto-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]].
