 For the remaining node-based DM users, during an upgrade to Zabbix 2.4.0, each upgraded node will be switched to a standalone Zabbix server keeping all configuration and history information from the local node and from the child nodes as well. For the remaining node-based DM users, during an upgrade to Zabbix 2.4.0, each upgraded node will be switched to a standalone Zabbix server keeping all configuration and history information from the local node and from the child nodes as well.
  
-To maintain uniqueness of data from non-local nodes, all the fields will be prefixes ​with N<​nodeid>​_. If the length of the new value exceeds max field size, it will be trimmed. Highly unlikely, but if the new value already exists in the database, the situation will be caught by a check on duplicates. Global macros will be processed in a special way by adding N<​nodeid>​_ after the dollar sign, for example, {$N123_MACRO}.+To maintain uniqueness of data from non-local nodes, all the fields will be prefixed ​with N<​nodeid>​_.

 While offering quite a bit of flexibility,​ creating custom graphs was not particularly quick or easy to maintain, especially, if you wanted to compare a handful of items where their respective hosts were created and then deleted after a while. To address this issue it has now been made possible in Zabbix to create ad-hoc graphs for several items in a very quick way. While offering quite a bit of flexibility,​ creating custom graphs was not particularly quick or easy to maintain, especially, if you wanted to compare a handful of items where their respective hosts were created and then deleted after a while.

-For that, similarly as for accessing simple graphs, you go to //​Monitoring//​ -> //Latest data//​. ​This section has gained a larger filter offering ​the possibility to filter the exact set of items you want, and the items now also have checkboxes in the listing.+For that, similarly as for accessing simple graphs, you go to //​Monitoring//​ -> //Latest data//​. ​

 +The section ​no longer ​has the host and host group selection dropdowns. Instead, those two choices can be made within an expanded ​filter ​section, which can be used flexibly for displaying ​the exact set of items you want. Additonally, items now have checkboxes in the listing.

 Note that the old operators are no longer supported, so the new ones have to be used instead. Note also that the new **and**, **or**, **not** operators are case-sensitive and must be surrounded by spaces or parentheses. For more details, refer to the [[manual:​config:​triggers:​expression#​operators|trigger operator]] section. Note that the old operators are no longer supported, so the new ones have to be used instead.
