A complete list of solved issues for 7.4.1 are listed in the [project development portal](https://github.com/OpenNebula/one/milestone/94).

## Upgrading to 7.4.1

{{< alert title="Important" type="warning" >}}
Unlike most maintenance releases, OpenNebula 7.4.1 includes changes to the stock configuration files and ships `onecfg` migrators from 7.4.0 to 7.4.1. After upgrading the packages you **must run `onecfg upgrade`** on the Front-end to migrate your configuration, as described in the [upgrade guide]({{% relref "software/upgrade_process/upgrade_guide/upgrading_single#step-7-update-configuration-files" %}}).

{{< alert title="Note" type="info" >}}
Maintenance releases (`X.Y.Z`) usually do not change the configuration files, so `onecfg upgrade` simply confirms that the configuration is up to date. **OpenNebula 7.4.1 is an exception**: it ships `onecfg` migrators from 7.4.0 to 7.4.1, and `onecfg upgrade` must be run to migrate the configuration to the new version. See [Step 7 of the upgrade guide]({{% relref "upgrading_single#step-7-update-configuration-files" %}}) for details.
