Firmware upgrade from lowest to latest

Hi 

My WD TV Live Hub firmware:  2.02.19

I want to know if I can directly apply the firmware upgrade to the latest  3.12.13  from the one I have which is 2.02.19?

Does the latest include all the previous fixes and updates?

Or should I have to apply one by one to the latest?

Please advice…

Thank you

Just connect it to your network so that it can access then internet.  Then let it upgrade to whatever version it wants to upgrade.
