Support for more file formats

Version 7.4 brings support for new file formats:

  • documents — mhtml, stw, sxw, wps, wpt;
  • spreadsheets — et, ett, sxc;
  • presentations — dps, dpt, sxi.

Further parameters for the setUsers method

The setUsers method sets a list of users to mention in the comments or grant the access rights to edit the specific sheet ranges.

The newly added field defines the identification of the user. It is used only for protecting the sheet ranges when granting editing rights to the specified user.

And the newly added c parameter defines the operation type from the onRequestUsers event. It can take one of the following values – mention or protect.

    "c": "protect",
    "users": [
            "email": "",
            "id": "78e1e841",
            "name": "John Smith"
            "email": "",
            "id": "F89d8069ba2b",
            "name": "Kate Cage"


From now on, the drawing functionality is available in each editor.

Users of ONLYOFFICE Docs Developer Edition with the extended licenses are able to display or hide this new Draw tab via the editorConfig.customization.layout.toolbar parameter.

Font size customization

The newly added size field, in the editorConfig.customization.font parameter, allows adjusting the font for the interface elements such as buttons, tabs, etc.

Please note: this option is available for users with the extended developer license.

Support for the Chinese dameng database

Among the supported database types there is the Chinese dameng. To connect it, change the database type to dameng. For example, for Docker you will need to adjust the DB_TYPE parameter.

Other updates

  • The useforrequest WOPI IP filter parameter changed to false.
  • mobileView and mobileEdit for WOPI discovery.
  • Updated node-redis connector.

API enhancements for plugins

Thanks to the extended API, plugins can now have as many windows as you want (for example, you can execute a custom script in a separate window) and be dynamically embedded in the context menu of the editors. It gives you more freedom and enhances the number of possible usage scenarios for plugins.

One of the brightest examples here is our updated ChatGPT plugin. From now on, it provides more useful features such as word analysis, image generation, text summarization and keyword generation, translation, etc. Learn more

With the pluginsmanager server utility admins are now able, when a manual installation is required, to install or uninstall plugins with a single command line, instead of copying the folders, e.g.:

pluginsmanager --install zotero

pluginsmanager --install "zotero, chess"

pluginsmanager --uninstall zotero

Besides, we added lots of new events and methods for working with plugins, including:
