Should I upgrade from 4.4.5.2 to 5.0?

libre calc 4.4.5.2

Windows 7 64 bit

I think so.
Go to http://www.libreoffice.org/download/libreoffice-fresh/?type=win-x86_64&version=5.0&lang=it and download the new version 64 bit per Windows.

I’m running Linux Mint 17.2 and tried to download and install 5.0 with no success. I did it all from the terminal command line and, while there were no error messages, LibreOffice 5.0 never appeared as “installed” on my computer. When I pull it from the Menu/Office list I end up with 4.4.3.2 and when I check Synaptic only 4.4.3 rc2 appears in the list of options.
