Is the "split window" option gone?

I just upgraded my ubuntu from 15.10 to 16.04. On the old system I had libreoffice on the newer system

On the old version in libreoffice calc there is an option “Window → Split Window” (and also freeze Window). In the new version this option is gone. Why was this removed? Is this feature available in an other menu in the new version?

Click View, options are listed.

You can also click Tools/Customise…/Toolbar and tick the options to appear on the toolbar.

Sorry! my post crossed yours.

The split rulers are still present (may look a bit different).
The ‘Split’ and the ‘Freeze’ are now items of the ‘View’ menu.
