#### Agent interface availability behavior

The host [availability](/manual/web_interface/frontend_sections/data_collection/hosts#overview) behavior for Zabbix agent interfaces has been updated:

- if active checks are available, but at least one Agent interface (passive) is unknown while the host also has at least one item using this interface, the total Agent interface availability is displayed as gray (unknown);
- if active checks are available and all Agent interfaces (passive) are unknown (and no items are using this interface), the total Agent interface availability is displayed as green (available).

#### New templates

A new template is available:

- [YugabyteDB by HTTP](https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/db/yugabytedb_http?at=refs%2Fheads%2Frelease%2F6.4), which includes the *YugabyteDB Cluster by HTTP* template for monitoring each YugabyteDB cluster.

You can get this template:

-   In *Configuration* → *Templates* in new installations;
-   If you are upgrading from previous versions, you can download new templates from the Zabbix [Git
    repository](https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates?at=refs%2Fheads%2Frelease%2F6.4)
    or find them in the *zabbix/templates* directory of the latest Zabbix version you have downloaded.
    Then, while in *Configuration* → *Templates*, you can import them manually into Zabbix.
