# 13 Upgrade notes for 2.2.5

**Template changes**

Item descriptions have been fixed in the following templates:

-   Template JMX Tomcat
-   Template OS FreeBSD
-   Template OS HP-UX
-   Template OS Linux
-   Template OS OpenBSD

In order to fix it, import these templates from
<https://www.zabbix.org/wiki/Zabbix_Templates/Official_Templates>.

**Daemon changes**

Support for PHP mutexes has been removed on the server side due to
licensing issues. While it was not recommended to use Zabbix server and
frontend with SQLite3 database before, this change makes it even less
recommended, because simultaneous database access with Zabbix server and
frontend may now corrupt the database. Note that using Zabbix proxy with
SQLite3 database is still a perfectly valid solution.
