We really want to use this time before 2.0 is released to find bugs and make sure the 2.0 upgrade goes as smoothly as possible for everyone who upgrades. But in order to do that, we need people testing the beta.
It's super-easy to test, too. All you need to do is install the Genesis Beta Tester plugin, and you'll enable the ability to 1-click upgrade to the beta.
So, there's no reason not to test. Anyone who uses Genesis has access to the 2.0 beta. We don't limit access to a certain group of users. You can help provide valuable feedback to us before our biggest upgrade ever.
