-Note that the LibYAML library (version ​2.0.2 or higher) ​is now required ​for configuration ​export ​to YAML.+==== Modbus support ==== 
 + 
 +Zabbix now supports Modbus out-of-the-box using the new **modbus.get[]** agent and agent item. 
 + 
 +See also: 
 +  * Zabbix agent [[:​manual/​config/​items/​itemtypes/​zabbix_agent#​supported_item_keys|item keys]] 
 +  * Zabbix agent 2 [[:​manual/​config/​items/​plugins|plugins]] 
 +  * Modbus [[https://​git.zabbix.com/​projects/​ZBX/​repos/​zabbix/​browse/​src/​go/​plugins/​modbus/​README.md|plugin documentation]] 
 + 
 +==== MQTT support ==== 
 + 
 +Zabbix now supports receiving values of MQTT topics using the new **mqtt.get[]** agent item. 
 + 
 +See also: 
 +  * Zabbix agent 2 [[:​manual/​config/​items/​itemtypes/​zabbix_agent/​zabbix_agent2|item keys]] 
 +  * Zabbix agent 2 [[:​manual/​config/​items/​plugins|plugins]] 
 +  * MQTT [[https://​git.zabbix.com/​projects/​ZBX/​repos/​zabbix/​browse/​src/​go/​plugins/​mqtt/​README.md|plugin documentation]] 
 + 
 +==== Digest authentication for HTTP agent ==== 
 + 
 +Digest authentication ​is now supported ​for [[:​manual/​config/​items/​itemtypes/​http|HTTP agent]] items and in [[:​manual/​web_monitoring#​configuring_authentication|web scenarios]]. 
 + 
 +==== Support of tags for host prototypes ==== 
 + 
 +[[:​manual/​vm_monitoring#​host_prototypes|Host prototypes]] now support tags with a possibility to use LLD macros as tag values. This functionality allows to assign each discovered host own set of tags with valuable information (datacenter,​ instance type, resource type, etc.), which can be useful, for example, in the discovery of cloud resources. 
 + 
 +==== Agent configuration ​parameter for default search path ====  
 +A new optional parameter **UserParameterDir** has been added to the Zabbix [[manual/​appendix/​config/​zabbix_agentd|agent]] and [[manual/​appendix/​config/​zabbix_agent2|agent 2]] configuration files. The parameter specifies a custom directory to execute UserParameter commands from. If UserParameterDir is present, the agent will change its working directory to the one specified by this parameter before executing a UserParameter command. Thereby UserParameter commands can have a relative ''​./''​ prefix instead of a full path. 
 + 
 +Example: \\ ''​UserParameterDir=/​opt/​myscripts''​ \\ ''​UserParameter=check_cpu,​./​custom_script.sh''​
  
 ==== Macros ==== ==== Macros ====
  
   * {ITEM.LOG.*} [[:​manual/​appendix/​macros/​supported_by_location|macros]] are now also supported in:   * {ITEM.LOG.*} [[:​manual/​appendix/​macros/​supported_by_location|macros]] are now also supported in:
-    * trigger names, operational data, URLs and descriptions +    * trigger names, operational data, URLs and descriptions; 
-    * event tags and values+    * event tags and values
 +  * User macros are now supported in item and low-level discovery rule descriptions. 
 +  * User macro length limit has been increased from 255 to 2048 characters. 
 +  * New macros have been added: 
 +    * {ITEM.DESCRIPTION.ORIG<​1-9>​} resolves to the item description without macros expanded. 
 +    * {LLDRULE.DESCRIPTION.ORIG} resolves to the low-level discovery rule description without macros expanded.

 +=== Minimum required PHP version ===
 +
 +The minimum required PHP version has been upped from 7.2.0 to 7.2.5.
 +
 +=== Informative tabs ===
 +
 +Tabs in many frontend forms now indicate the number of defined elements or if the functionality is enabled. To illustrate let's compare a host configuration form with two linked templates, one host tag, one host-level macro, enabled inventory and two-way encryption enabled now and before:
 +
 +|{{:​manual:​introduction:​host_new.png|}}\\ Host configuration in Zabbix 5.2.0. ​ |
 +|{{:​manual:​introduction:​host_old.png|}}\\ Host configuration before Zabbix 5.2.0. ​ |
 +
 +Informative tabs allow to debug problems easier, for example, when an item has preprocessing steps defined they are now clearly indicated with a number even when the tab is not opened:
 +
 +{{:​manual:​introduction:​item_ba.png|}}
 +
 +Informative tabs have been added to the configuration forms for:
 +
 +  * Hosts and host prototypes
 +  * Templates
 +  * Items and item prototypes
 +  * Triggers and trigger prototypes
 +  * Discovery rules
 +  * Web scenarios
 +  * Actions
 +  * Services
 +  * Proxies
 +  * Authentication
 +  * Users and user groups
 +  * Media types
 +  * Graph widgets
 +  * Maps
 +  * User settings

 +=== Session stored in cookie ===

-Searching for the required dashboard has become easier with these new features:+Switching to the required ​[[:​manual/​web_interface/​frontend_sections/​monitoring/​dashboard#​viewing_dashboards|dashboard]] ​has become easier with these new features:
  
   * List of all dashboards now has a filter, allowing to search for dashboards by name and to switch between displaying all dashboards and dashboards created by the current user.   * List of all dashboards now has a filter, allowing to search for dashboards by name and to switch between displaying all dashboards and dashboards created by the current user.

 Additionally,​ it is now immediately visible, which dashboards are shared with other users. If a dashboard is public or is privately shared with any user or user group - a tag "​Shared"​ next to the dashboard name will indicate that. Additionally,​ it is now immediately visible, which dashboards are shared with other users.

 +=== Simplified Maintenance periods form ===
 +The [[:​manual/​maintenance|Maintenance periods]] configuration form now has a simpler single-tab look. All configuration parameters previously located on the tabs //Periods// and //Hosts and groups// have been moved to the primary tab.
