Zabbix 3.0, What's new - Parte 5

Predictive trigger functions: Predictive capabilities are now available via forecast() and timeleft() trigger functions. These functions analyse item history and return the future value of the item or time in which the item value reaches a threshold respectively.
Multiple OID support in SNMP discovery: SNMP discovery has been improved to support discovery of multiple OIDs.
Host availability improvements: In the new version, displaying host availability has been made much more accurate.
