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

Using [`pg_restore`](https://www.postgresql.org/docs/current/app-pgrestore.html) 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`](https://www.postgresql.org/docs/current/app-pgdump.html).

See [known issues](/manual/installation/known_issues#database-restore-error-with-postgresqltimescaledb-after-upgrade-from-7.0.0-7.0.4) 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](/manual/appendix/install/timescaledb#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](https://repo.zabbix.com/zabbix/6.0/rhel/6/x86_64/) 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](/manual/installation/install_from_packages/rhel) are still supported.

#### Item value widget

Line breaks are now observed when displaying a textual value with line returns in the *[Item value](/manual/web_interface/frontend_sections/dashboards/widgets/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.
