A couple of things have changed but nothing really that bad. PHP version has gone from v5.2 to v5.4 and a couple other behind-the-scenes versions have gone up.
Once I do some speed tests I'm thinking of adding the new live threads update. Remember how live threads used to update without refreshing? Well, we can do that again, but I worry about load times.
Oh, and on the 26th of this month we will be updating to at LEAST version 1.1.3 (or 1.1.4 if it's released by then) and then adding a Resource Manager. What does that do, you ask? Well, it'll allow us to do things like item reviews, for one. Right now I don't know what exactly we'll use it for, but they are going to sell it for $20 so I'd be stupid to pass it up. It'll go to $60 after the 26th, so it's worth it to get it.
If you see an error message, try and get a screen print if you can. Even if you can't, let me know so I can check the server logs.
