### Breaking changes

#### Loadable plugin versioning

[Loadable plugins](/manual/config/items/plugins#loadable) for Zabbix agent 2 now use the same versioning system as Zabbix itself. The following version changes have been made:

- MongoDB 1.2.0 -> MongoDB 6.0.13
- PostgreSQL 1.2.1 -> PostgreSQL 6.0.13

These plugins are supported for any minor version of Zabbix 6.0. 
Note that source code repository for each plugin now contains a dedicated *release/6.0* branch (previously, there was only *master* branch).

### Query separate tablespaces in Oracle databases with Zabbix agent 2

The following [Zabbix agent 2 items](/manual/config/items/itemtypes/zabbix_agent/zabbix_agent2), supported for the Oracle plugin, now have additional optional parameters:

-   oracle.diskgroups.stats\[<existingParameters>,**<diskgroup>**\]
-   oracle.archive.info\[<existingParameters>,**<destination>**\]
-   oracle.cdb.info\[<existingParameters>,**<database>**\]
-   oracle.pdb.info\[<existingParameters>,**<database>**\]
-   oracle.ts.stats\[<existingParameters>,**<tablespace>**,**<type>**\]

These parameters allow to query separate instances of data instead of all data, thus improving performance.

### Open file descriptor limit increase for Zabbix agent 2

The systemd service file shipped in Zabbix agent 2 packages now declares the open file descriptor limit of 8196.
Previously, the system default limit of 1024 has been used.
The new limit is sufficient for the default Zabbix agent 2 configuration.
If you have a non-standard agent 2 configuration, for example, use additional plugins or extended features, this limit may need to be manually increased further.
In this case, adjust the `LimitNOFILE` parameter in the systemd unit file.
