11 Upgrade notes for 6.0.1

Configuration syncer

Performance of the configuration syncer has been improved. It is recommended to increase the CacheSize on server/proxy if there is a large amount of templates. It is also recommended to remove unused templates.

Note that the default CacheSize on server/proxy has been increased to 32M.

Item changes

Native support for the items net.dns and net.dns.record has been added to Zabbix agent 2. On Zabbix agent 2 for Windows, these items now allow custom DNS IP addresses in the ip parameter and no longer ignore timeout and count parameters.
