 +===== 5 What's new in Zabbix 5.0.0 =====
 +
 +<note important>​Zabbix 5.0.0 is not released yet.</​note>​
 +
 +=== Item key limit raised ===
 +
 +The maximum allowed length of an item key has been raised from 256 to 2048 characters.
 +
 +=== Restricting agent checks ===
 +
 +It is possible to restrict checks on the agent side by creating a whitelist or blacklist of allowed item keys.
 +
 +Whitelist/​blacklist is created using a combination of two new agent [[:​manual/​appendix/​config/​zabbix_agentd|configuration]] parameters:
 +
 +  * ''​AllowKey=<​pattern>''​ - which checks are allowed; <​pattern>​ is specified using a wildcard (*) expression
 +  * ''​DenyKey=<​pattern>''​ - which checks are denied; <​pattern> ​ is specified using a wildcard (*) expression
 +
 +See also: [[:​manual/​appendix/​config/​restrict_checks|Restricting agent checks]]
 +
 +=== Stronger cryptography for passwords ===
 +
 +A stronger bcrypt cryptography is now used for hashing user passwords instead of MD5. The change to the stronger cryptography after the upgrade is automatic, i.e. no effort on the user side is required. Note that passwords longer than 72 characters will be truncated.
 +
 +=== Support of IBM DB2 dropped ===
 +
 +The IBM DB2 database is no longer supported by Zabbix.
 +
 +=== Using HTTP proxy in webhooks ===
 +
 +It is now possible to specify an HTTP proxy when configuring a [[:​manual/​config/​notifications/​media/​webhook|webhook]]. The new HTTPProxy parameter is listed in the webhook parameter list by default with an empty value. ​
 +
 +When specifying the proxy value the same functionality as in the item configuration [[:​manual/​config/​items/​itemtypes/​http#​configuration|HTTP proxy]] field is supported.
 +
 +=== Mass unlinking of templates ===
 +
 +It is now possible to mass unlink templates when using host or template mass update:

 +{{:​manual:​introduction:​hosts_mass_unlink.png|}}
 +
 +See also:
 +
 +  * Host mass [[:​manual/​config/​hosts/​hostupdate|update]]
 +  * Template mass [[:​manual/​config/​templates/​mass|update]]
 +
 +=== Page selection dropdown integrated into headings ===
 +
 +Some frontend sections in Zabbix may display a different page depending on user selection. For example, //​Administration//​ -> //General// may display twelve different pages. ​
 +
 +Previously, the page selection was made in a rather small, easy-to-miss dropdown located in the top right corner of the page. Now that selection has been integrated into the headings on the left.

 +|In Zabbix 5.0.  |
 +|{{:​manual:​introduction:​adm_general_old.png?​600|}} ​ |
 +|Before Zabbix 5.0.  |
 +
 +This change affects the following sections:
 +
 +  * //​Monitoring//​ -> //​Overview//​
 +  * //​Monitoring//​ -> //Screens//
 +  * //​Configuration//​ -> //Actions//
 +  * //​Administration//​ -> //General//
 +  * //​Administration//​ -> //Queue//
 +=== Detail editing as popup window ===
 +
 +In several configuration sections of Zabbix frontend detail editing is now opened as a popup window. This is implemented for:
 +
 +  * Action conditions
 +  * Global correlation conditions
 +  * Action operation details ​
 +    * in the [[:​manual/​config/​notifications/​action/​operation#​configuring_an_operation|Operations]],​ [[:​manual/​config/​notifications/​action/​recovery_operations#​configuring_a_recovery_operation|Recovery operations]] and [[:​manual/​config/​notifications/​action/​acknowledgement_operations#​configuring_an_update_operation|Update operations]] tabs
 +  * Maintenance period details ​
 +    * in the [[:​manual/​maintenance#​configuration|Periods]] tab
 +  * Discovery rule details
 +    * see discovery [[:​manual/​discovery/​network_discovery/​rule#​rule_attributes|check]] editing
 +
 +In many cases this change allows to de-clutter the interface of having to configure too many options in one screen. For example, details of an action operation are now opened in a separate popup window.
