A few questions:

1.) If I'm using v. 0.90 as my offline wallet and don't want to upgrade, do I need to use an older version of Armory for my online wallet?

2.) If so, where can I download 0.90? I can't find it at https://btcarmory.com or https://www.bitcoinarmory.com/.

3.) Which is the official site  https://btcarmory.com or https://www.bitcoinarmory.com ? I find it very confusing that there are two sites where you can download wallets given the security risks involved.

Thanks in advance!
