Updating from Meteohub 4.5i

[hasteiner]

Hi All,

I have been quite happy with my Meteohub 4.5i for a while now, and have been quite happy just letting it tick along and collect data. It is running on an ALIX 3D3.

I am wondering two things however,

1/ Is there anything I would want that would make it worth updating to 4.6?
2/ Can I click update and expect it to work, or do I need to take some additional steps to make the upgrade successful?

Thanks
Hugo
