Update to Beta or not?

[aforeffort 0]

Hello, I'm completely new to the ARMA series/game and also DayZ. I'm currently downloading and installing the game but I'm really confused about the patches. When I've installed Arma 2+Operation Arrowhead should I then update it to the "beta" patch? (Also, I don't really understand this, is this a beta patch for the DayZ mod or just the game itself?) What also confuses me is that there seems to be two different updates, for example I read somewhere about a 1.7.xx patch for DayZ and then there's this beta patch.

So what should be installed and what should not be installed?

I hope I didn't make the question confusing. :)

The beta patch is for Arma 2 Operation Arrowhead and you can get it here: http://www.armaholic.com/page.php?id=10989

The 1.7.1 patch is for DayZ and is currently not out yet.

It's not about doing it or not, pretty soon it'll be mandatory if you want to play, so get it now and get used to it.

It is recommended to install the ArmA 2 beta patch, because when DayZ version 1.7.1 comes out, everyone must have ArmA 2 beta patch installed in order to play it.
