23 What's new in Zabbix 4.0.18
libssh support
Support of the libssh library (starting from version 0.6.0) has been added. Previously only libssh2 was supported for SSH checks.
DB character set and collation check
A check for the correct character set and collation is now performed on the database, database tables and table fields during the initial frontend installation. If the check fails a warning message is displayed.
A warning message is also displayed in Reports → System information.
See also instructions for changing database character set and collation in MySQL.
Internal events can be disabled
Internal events will not be created, if all internal actions for them are disabled --- this can be useful for reducing the amount of event records and controlling the size of the event tables. See more information.
