# 11 Upgrade notes for 4.2.2

#### Frontend

-   In this version only, *write* permissions to the `assets` directory
    are required for the web server user. (See also [known
    issues](/manual/installation/known_issues#known_issues_in_422).)
-   The `styles` folder has been moved to the `assets` directory, which
    is important if creating a [custom
    theme](/manual/web_interface/theming).
-   Media types in the *Action log* dashboard
    [widget](/manual/web_interface/frontend_sections/monitoring/dashboard/widgets#action_log)/screen
    [element](/manual/config/visualisation/screens/elements#action_log)
    are now sorted by media type ID instead of media type name.
