16 Upgrade notes for 7.0.5

Breaking changes

Database restore error with PostgreSQL/TimescaleDB after upgrade from 7.0.0-7.0.4

Using pg_restore to restore a PostgreSQL/TimescaleDB backup created in Zabbix 7.0.0-7.0.4 will result in a missing base36_decode function error, causing the restore to fail. This error occurs when restoring a backup created with pg_dump.

See known issues for details on fixing this issue manually before creating the backup.

If you have not upgraded to Zabbix 7.0.0 yet, note that there should be no such issues for upgrades from pre-7.0 Zabbix versions to 7.0.5. For upgrade instructions, see Upgrading TimescaleDB schema.

Agent 2 package support for RHEL 6 dropped

Since Zabbix 7.0.5, Zabbix agent 2 packages are no longer available for RHEL 6 due to Go 1.22 (and newer) being incompatible with GCC 4.4.7 provided by RHEL 6, which results in compilation errors. Note, however, that Zabbix agent packages are still supported.

Item value widget

Line breaks are now observed when displaying a textual value with line returns in the Item value widget with display option set to "As is". Additionally, no wrapping has been implemented in case of "As is" display with horizontal layout or vertical layout with one column. With vertical layout and more than one column word wrapping is observed.
