Previously, if Zabbix could not send ICMP ping packets to a particular host, all ICMP ping items would attain a value of 0 in some cases. Now, they always become unsupported.
A check for valid reference has been added for global regular expressions in LLD rules. If entered reference is not valid, due to misspelling or missing referenced global regular expression, the respective LLD rule will become unsupported and appropriate error message will be displayed.
