LibreOffice Calc Pivot Tables

The Pivot Table menu (under the data menu) is not active.
This is a functionality that was available in LO Calc 4.4
Unfortunately I updated to 5.1 and lost this capability.
I need a solution. Where can I find the LibreOffice_4.4.4_Linux_x86-64_deb.tar.gz download to recover the ability to use Pivot Tables in Calc?

The pivot table create function is now under the Insert menu item. Once the pivot table is created and selected the Data/Refresh or Delete commands become active.

It looks like the Help entry for Creating Pivot Tables is a bit behind the curve.
